Message-ID: Date: Wed, 18 Jan 2006 15:50:04 -0500 But why use a thermistor and additional parts to replace readily available $5 (NEW) tube which provides the appropriate delay and voltage as designed? That being said, I have used thermistors or "inrush current limiters" to protect valuable AC radios that use directly heated rectifiers and that are played infrequently. I use the CL90 available from Mouser (527-CL90) rated at 120 ohms cold and 2 amps. I place them, along with a slow-blow inline fuse, in the PRIMARY of the power transformer.

Why not just ring Jim Marshall, and ask ? They're only up in Milton Keynes, and are a pretty friendly company. FWIW, for a paralleled pair of EL34s in this application, I'd say that the readings you have obtained are fair. If it has been standing for a long time, I would strongly advise bringing the power up slowly on a variac. The main resevoir and smoothing caps, may not be in a state to accept HT right away, and might need reforming. If you are a reader of " Television " magazine, look out for the new one that will be coming out at the end of March. It's going to be called " Technology @ Home ", and when I get round to it, you can read my ramblings on repairs to valved group and PA amps.

I would guess the poles were 10 ft. long and the balls maybe 9 in. diameter. However, judging from on the ground and 50 years away I might be way off. The last time I saw one was in the 70s. When I asked what they were, I was told that they were radio antennas. Does anyone know anything about these? If they were antennas, was there something special about the ball or was it just decoration? When were these new? Does anyone have a picture?

I presently have a stereo that was bought on impulse from Sears. I don't even know the name -- it might be Pioneer. It has a digital tuner, and 10 presets -- and each of the presets can be set to three stations. If you push it once, it goes to one FM station. If you press it twice, another, and if three times it goes to an AM station. It has all sorts of tape monitors and VCR inputs, has some sort of surround capability, and al sorts of modes which are displayed through little hierogliphics on the digital screen. What it doesn't have is loudness, or any sort of ease of operation. I've got a DBX expander and an equalizer in the mix somewhere, with a tape deck, but I honestly can't figure out how to play the music through the DBX/equalizer. It is the most confusing piece of nonsense I've ever seen! It is obviously not made for the purpose with which I'm using it (just plain stereo). Obviously no hurry on this, as I'm usually in the shop listening to an Atwater-Kent. But I've thought that someday I might pitch this thing for a real stereo -- and if I do this, why not something vintage that does a nice job? So -- we'll just wait to see what the future holds. -- Gary E.

This one is unique in that it has an IF stage. The usual tube line up goes 12AU6, 12AV6, 50C5, and 35W4. There are variations. I have a Silvertone model 1 (where did they get that number from?) that uses a 12SA7, 12SQ7, 50L6, and 35Z5. It works fine - - - - on local stations. I can see why a TRF might be attractive from a parts cost perspective, it eliminates the IF transformer without changing much else. However, the labor must have been significantly greater. Ever try to align a TRF? I did one once, with a 2 gang capacitor. It took about 2 hours IIRC; mostly spent bending capacitor plates to get it to track across the band so that reception would be decent. And this was a radio that had worked at one time.

Think of a vibrator as a mechanical source of AC to run the power transformer. You chop the 12 VDC on and off, and the transformer converts that into 150-200 VDC for the radio B+ supply. Poking about on the vibrator socket with an oscilliscope would give you an idea of what's happening.

Since you're not going to get a decent resonant length antenna, the next best thing is to capacitively couple to the signal. More surface area at the end of the wire. A metal sphere works well for this. Side note: In a lot of antique radio pictures, you see a large antenna array with multiple wires tied together with a single feed line coming down. The engineering term for this is a "Capacitive hat" at the top of the feed line. It is to help tune the entire array to resonance at the working frequency. Jeff -- RESTRICTED AREA.

Which I have read is/was a not too reliable tube; in respect of heater cathode shorts IIRC? Our radio was designed to work from around 100 v to 240 v, AC mains or field generator. Being European that was probably 50 hertz! It can also work on 12 volts DC using a vibrator and special windings on the power transformer. The whole radio is rated to consume 36 watts. The power transformer is therefore rather small, complicated and probably irreplaceable! The idea of removing 6.3v at 0.6a = 3.8 watts or approx 11% of the power load from the now 60+ year old transformer therefore seemed attractive. There is also no original fusing in the AC input or the B+! There IS a fuse in the 12 volt input using what appears to be an overly large Slydlok replaceable-wire fuse! The early 1940s set is constructed on three sub chassis, the heaviest being the power unit. Having seen adverts. for a number of these sets which have either been modified, converted, scrapped or, as one seller described 'been got at in the power section' would warrant performing several easily reversible modifications to preserve/protect the power section, especially the transformer . Summary: Remove 10% power load by replacing 6X5 with diodes. Add something to delay the immediate high B+ on filter (and other) caps at switch on. Add voltage dropping because of the lower forward voltage drop of diodes. Add fuses in a) AC primary b) Somewhere in the B+ circuit. Remove modification by previous owner which had already resulted in burn out of the original and 'almost' irreplaceable audio output transformer primary. I may have located a source of an original replacement which allow the unsatisfactory replacement to be removed. Overall any 'mods' to be obvious and easily removable for future authenticity.

Something like that, in general terms, a B+ time delay circuit, had 'sort of' occurred to me. I had a thermal delay relay in a glass B7G envelope, but it is broken! Perhaps I can experiment with a triac out of a scrapped microwave oven? But IIRC they work in the primary of the AC transformer which produces EHT and heater voltage for the microwave magnetron/diode and are triggered by the control circuit board. Not sure about that; I'll have to check. And to put a triac or other into the centre tap of, say, the transformer B+ secondary (at AC) would mean digging into the wiring; rather than some easily reversible and recognizable 'mod' mounted in a unit plugged into the rectifier tube socket above chassis! Fortunately lots of spare room around/above the rectifier socket! This thread has pointed out that in many sets the rectifier tube, such as a directly heated type 80, will heat fast enough that B+ at v'peak is applied before the other tubes have had time to heat and draw current! So filter caps have to be designed for that. In this case the existing 6X5, which am proposing to replace with diodes, to reduce power transformer wattage by some 10%, has an indirectly heated cathode (pin 8), with separate heater on pins 2 and 7. In this radio the 6X5 has a dedicated 6.3 volt power transformer winding, but pins 7 of the heater is connected to pin 8 cathode; meaning that the winding sits at the B+ voltage output of the rectifier. Same as the 5 volt rectifier heater winding in many 'normal' sets. Also someone has added a non-original electrolytic, mounted by being glued upside down to the power unit chassis. The other eight 6.3 volt tube heaters are in series parallel across another 12 volt winding (when using AC). There is a panel mounted indicator light and dial lamps that can probably be dimmed down to reduce power transformer load by one watt or so; or about another 3%. (LEDs?) Each Mullard type international octal tube (EF39/EBC33 etc.) consumes 6.3v at 0.2a; compared to typical 6K7/6Q7s at 6.3v 0.3a. Overall possibility, by removing the rectifier tube and using smaller pilot lamps, of reducing load on transformer by some 13% ? The whole thing is a 60+ years old cosmetically in good condition; a monster metal cabinet radio weighing 90 pounds. But senile nostalgia has set in! I had a then brand new ex-war surplus one of the same type, as a teenager over 50 years ago. So trying to lovingly preserve this one which cost me, somewhat used, ten times that of the original one! The only fuse in it, as originally manufactured, is in the 12 volt DC input; useful I suppose if the vibrator jammed? But it has no AC or B+ fuses! Therefore any 'ingenious' ideas, about the idea of delaying B+ application and/or removing a few watts from the irreplaceable power transformer or anything else are most welcome. Many thanks to all for the helpful comments and discussion sparking of ideas. Power consumption. Eight 6.3v tubes, series parallel pairs, 12 x 4 x 0.2a = 4.8 watts. (14%) Panel and dial lamps = approx 2 watts (6%) Rectifier 6X5, 6.3 x 0.6a = 3.8 watts (10%) B+ approx 250v @ 100m/a = 25 watts (70%) Total approx = 36 watts. Terry.

While the capacitor would block the flow of DC to chassis/ground and prevent the phones from being 'live' at B+ voltage (as they often were in the 'old days', would not that 'look' like a very low impedance to the tube? In other words a major impedance mismatch? An unusual suggestion might be, to experiment using any old power transformer? By connecting it's high voltage winding/s into the plate circuit (the DC resistance of any winding will be a few hundred ohms at most), and then connecting the low Z phones to one of the low voltage windings something of an impedance match at audio frequencies could be obtained?* Viz: 250 volt to 5 volt winding (ignore all other connections) would be a voltage ratio of 50:1 Thus an impedance ratio of 50 x 50 (times the headphone impedance of 150) = 2500 x 150 = 2500 x 150 = 375,000! Or using a 120/6.3 (a small filament transformer?) = 19.0:1 Thus 19 x 19 x 150 = 54,150! But a question; even if the 150 ohms is the DC resistance of the headphones what is the AC impedance? Maybe the impedance Z is somewhat higher? * One data sheet mentions the 1H5 triode with a plate current 0.275 milliamps! So DC flow through the transformer would be incidental.

Not these. Sometime back I participated in an argument about the 45 tube. Some of the posters here were upset about what happened to the price of 45s, and were quite vocal at the "audiophools" for driving up the price, depriving them of the tubes they need. Since then, whenever I get a 45 that isn't up to "audiophool standards" but tests and looks good I post it here - and (as Mark says too) I post it at a reasonable, fair price. The two tubes I have now would do great in many of the radios that use it I'm sure. No one here has ever bought one from me though, I'm not sure if I'm surprised or not... But anyway, the tubes I have need a good home, and some nice radios need a 45 that works and doesn't cost a zillion bucks. Jim McShane Need Tubes? Got a H-K Citation (Pre) Amp?

I hate to say this without actually having had my hand on one, but I *know* it was possible with the older models. From what I understand, there was a knob that protruded from the bottom of the fan.

Dave Don't know about long wave or medium wave, but it really doesn't take a lot of antenna to get good short wave reception. Back in the very early 80's, I was in the old Apple II computer club. There was an old guy in the club that knew I was a ham. Someone had given him a Drake SW-4 receiver and he wanted me to come over to his house and show him how to use it and to show him what kind of antenna to put up. I asked him if he had a paper clip. He said yes and brought it over to the radio. I unfolded it and put it in the antenna jack and then proceeded to tune in half a dozen International broadcast stations--granted, it was BBC and the rest of the usual powerhouses. Ultimately, we ended up with about 10 feet of wire put up with thumbtacks in the ceiling of his back porch. He wasn't an "ultra serious" DXer, but he heard *plenty* with that ten feet.

I had some vague ideas about how sound distribution systems operated, never having worked on them with those '70 volt line' transformers; but had never realized that they could have such a useful range of ratios for matching impedances! Makes sense. I would imagine those transformers used to attach speakers attached to the sound distribution line around a building never have to deal with DC current? Only the AC voice/music signal. So again I would comment that unlike the 'output transformer' in most tube sets, which attaches directly to a speaker and which will have the magnetising effect of quite a few milliamps of DC current flowing through its primary, from B+ to the tube plate, we are with a 1H5 dealing with very small dc current. In effect neglegible. . > I think OP said 150 was the impedance. I'd have to look back. Sounds > suspiciously like sound powered phones :) > The OP said "a modern set of 150 ohm headphones ......? ". It's interesting that in a second posting "The 2000 ohm phones are 'much louder' ". That certainly suggest quite a few more decibels power reaching the headphones which supports the idea of better (more efficient) impedance matching and therefore energy transfer! So would respectfully suggest that any experiments which will result in better 'matching' (i.e. more effective transfer of audio power) from the tube circuit to the headphone circuits would be productive and informative. > BTW using a choke in the plate as high impedance but still shunting by low Z phones to chassis/ground won't I think make much difference? DC voltage on the plate may be slightly higher not having to flow through say a 50K resistor with consequent voltage drop but there would still not be a 'good impedance match' between plate output and the load (headphones)? > PS. Reason for suggesting an old power transformer. They are often available and while designed for AC power transfer at either 60 or 50 hertz/cycles will probably work OK at typical audio/music frequencies used in broadcasting?

In most cases I would say yes but since the 1H5 plate is operating at such a low current you can plug in fairly high resistance and not take too big a hit on the plate voltage.

Even if the xfmr doesn't give the desired turns ratio you can use its highest Z (or R) winding and it will make a dandy AF choke to use in the above scenario.

Especially about contrary to NEC. I guess you mean that my now deliberately grounded (AC electrically as it were) chassis could then be grounded 'again' if/when I have a solid ground at the antenna connection location. I'll examine the antenna input circuit before doing so; good point, thanks for the warning! That has some connection with a remote coax fed antenna aperiodic (untuned) matching system to an existing antenna in the trees, that will also be separately grounded to drain off (perhaps) static! Also the fact that any 'house' ground can be a pretty noisy source particularly with today's dimmers, fluorescents, computers, TV sets and many other electrical gadgets. Thanks for advice re sizing of slo-blow; realizing that the fuse MAY prevent damage. Better'n than none I guess! Terry.

In effect neglegible. I've been advised against using them as an output xfmr in a tube radio due to the DC current issue and/or unknown voltage breakdown specs. Maybe I've been lucky but I have ignored the good advice and they have worked well for me in "regular" tube radios (6F6, etc) :) Thats a 'good thing' in that you can often find nice 8" PA system speakers with the 70.7v xfmr attached on ebay for a few bux and that works out well for replacing a missing spkr in an old set. -Bill Article: 329496 of rec.antiques.radio+phono From: " Uncle Peter" References: <4V8Af.14957$924.240762@news20.bellglobal.com> <1137785598.642641.230980@g43g2000cwa.googlegroups.com> Subject: Re: Adding AC primary fuse to Hallicrafters S-53 Message-ID: <0HdAf.9262$bF.3657@dukeread07> Date: Fri, 20 Jan 2006 17:41:54 -0500 "Terry" wrote in message news:LcdAf.22041$xk1.576881@news20.bellglobal.com... > > " > > > Thanks Neil. > Especially about contrary to NEC.

That precludes the oroblem of grounds at different potentials. You can safely ground the chassis to the ground wire in the power cable, but AC neutral and ground lead should NEVER be tied to a chassis as some people have done in other newsgroups.
