But the North-American culture is quite different from the European one. Reminds me a the guy who barged in a French Forum and "requested" a schematic for a French radio and was "annoyed" by the fact no one complied to his "request" or even replied to his post. Someone else was smart enough to know the difference and asked me to work as an intermediate... I got the schematic for free and made contact with very nice people within 4 hours on the very same forum...And I was extremely pleased to learn I could buy a CD full of schematics for a mere 25$...

Message-ID: Date: Mon, 13 Mar 2006 12:22:16 GMT Yeah, the AM Audio bandwidth reduction sucks. We dropped both of ours to 6khz. I can tell the difference on a few of my radios, namely the Philco 42-1010 and the RCA International console. I did an A-B test of our AM music station with my car radio and a couple boombox type portables and couldn't hear the difference. Right now, CC's focusing on HD Radio in the larger markets. We're in a pretty small market here, so we're low on the priority list. My AM's are probably a ways off since they're both directional arrays, which will take a little more engineering work. Luckily, one had been AM stereo, so it's in good shape. The other just got a phasor rebuild and new feedline, so it should have the necessary bandwidth to make it happen. The fun part will be making sure the sidebands are symmetrical.

Pulled out they test good with a solid state B&K checker. But I suspect one or two has drifted. Watch out for low tolerance markings on those caps like +- 5%. Especially the mica dipped (smooth dark brown/red ones) around 1 to 10 puff (pF). I am going to go back and check a few of the above mentioned caps with an old school cap tester. BTW - I got the oscillator to oscillate at normal amplitude. Seems some one fussed with the slug in the first plate choke (10 meter A band) of the heterodyne oscillator and put the wrong one in. The choke could not reach the needed uh about 2 for proper oscillation. I put a second slug in to it and WOW. The amplitude popped right up. It still has two dead crystals and a few that have significantly drifted off. I have one on order. I am currently linearizing the Second and Driver circuits for the required <1db variance. This is where skill meets technology. One has to detune and fuss with the coils until the amplitude of the stage is linear over the band. What a learning curve! What a dog.

Message-ID: Date: Mon, 13 Mar 2006 13:36:39 GMT A couple thoughts: 1) The typical field coil resistance that I have seen in anywhere from 800 to 1200 ohms. But this is for a Philco radio using the field coil as part of the power supply filtering. 2) Have you tried a lower DC resistance field coil? That should reduce the power consumption provided it is hooked up as a filter. Watch out for the increase in B+. BUT - Before lowering the field coil resistance, Is it hooked up in a manner to provide power supply filtering as a choke from one cap feeding another? If not (like you said parallel from B+ to ground) then don't do this. 3) It is the current through the field coil that will yield the most flux density. Not the voltage or the resistance. That said, if you can get the current up but keep the voltage lower then you will get less power consumption (I squared R losses) and more flux density (i.e., ability for the voice coil to oppose the field and move). However, I did not plot I vs. E charts. Your config has 70 ma of current dropping 425 volts. A series wired field coil for example in the Philco 40-180 (http://www.nostalgiaair.org/Resources/336/M0013336.htm) has 85 volts (270 - 185 final B+) across a 1100 ohm field coil. That yields 77 ma. More flux. Potentially louder mechanical output. Perhaps not only fabricating the part wrong they hooked it up wrong too. Like taking a circuit that uses a PM speaker and swapping out an Electrodynamic. Instead of using the field coil as part of the B+ filtering they did what seemed to be the easiest. Paralleling across the B+. The RDH4 did not have much on how to wire a field coil up (unless I missed it). I really can't remember ever seeing that config (B+ to ground). Can you post a schematic on the binaries? Good luck. Sound like a cool challenge.

Message-ID: Date: Mon, 13 Mar 2006 09:02:51 -0500 I have seen LOTS of early 1930's "Depression" sets (4 tube TRF) that have a 2000 ohms DC (or so) field coil connected directly from B+ (rectifier cathode) to ground, BEFORE the filter choke. I would estimate it receives about 130 volts DC in this case. Don't know why they would do this, but I suspect the DC current consumption of the set is not high enough to drive a field coil used as a choke.

My girlfriend and I are using it as our daily TV(up to 4 or 5 hours some days).

Picture tube is still strong. It uses compactrons, but hey, its still vacuum tube technology . My question: My two cats love to sleep on top of the set while its on. I'm sure the top gets warm. Should I be concerned about X-rays emitting from the top of the shunt regulator? The HV rect is fully enclosed, and the shunt is basically surrounded except for the top. The top points to where my kittys bellys are. Are they in danger of X rays? If they are, could I glue sheet metal to the underside of the cabnits top? Thanks, Matt Davala, in Oregon.

Looks like I'm getting hooked. The set I just finshed is an Admiral (24D1 chassis) which uses a 16" round, funnel type CRT circa 1950. Works OK, but the IF's certainly need to be aligned to clear up some grainyness in the picture. I've got a Heath IG-75A sweep/marker generator, but the IF frequencies it covers seem to be about double the IF used in the Admiral (approx 45 MC, but the TV uses about 22 MC). I'm missing the manual for the Heath, and maybe it'll explain how to align the IF's, but its not obvious to me. Does anyone here have any experience with the Heath sweep/marker generator? Of course if anyone has a manual (copy or original), for sale, let me know.

I love to watch non copyrighted DVD's because they look "great". Copyrighted ones have crappy macrovision that comes through and there are some really annoying lines that show up at the top of the screen. I do have a modern surround system and pretty good speakers. Good enough to watch and listen to Lord of the Rings. All of the movies are non copyrighted and look wonderful on this old tube. I am 23 and I love my old tube tv. Although I do drool when I go to any store where they sell new TV's. I suppose I am stubborn about old technonogy.

I personally don't like it. On the AM's, we are not nearly as aggressive as the FM's. The sports talker is set to keep the voices up above the noise to try to get a few more miles out of the signal.

If you go back and look at television books from the 1940's, you'll find the subject explained in detail. One book in particular was BASIC TELEVISION By Grob, I believe the second edition, published around 1948. I don't have this book anymore, wish I did -- it's interesting because it it fully explains the RCA 630 TS, and also covers the CBS color-wheel system.

The xray danger was from several things. 1: picture tube running with hi voltage set too high. Shouldn't be above 25kv. 2: Picture tubes were usually surrounded by a shield. Heathkits had a chassis surrounding the crt that doubled as an xray shield. 3: most of the time these were SOFT xrays with a limited range. Only when the hv was set too high could the crt emit dangerous levels. 4: The worst problem was the hv regulator tubes, not the hv rectifier. There was a batch of 6BK4's (and a few other types) that were defective. These were beam triode tubes and the plate had to be in perfect alignment with the cathode. Some of these tubes had the plate mounted at a slight angle (not perfectly inline with the cathode) which would cause the electron beam from the cathode to strike the OUTSIDE of the plate. Xrays would then be emitted at right angles to the plate, or out the SIDES of the tube. When the tube was made correctly all of the electron beam went up into the inside of the plate tube and any xrays were emitted DOWN into the base of the tube. IIRC the bad tubes were recalled by the makers. Article: 331311 of rec.antiques.radio+phono From: "Matthew Davala" References: <5%jRf.8705$o41.3051@trnddc06> Subject: Re: Dangerous Color Telivision?

By the time control subjects -- laboratory mice that lived their entire lives in a sterile enviroment and were never subjected to any nasty compounds -- die of old age, they're often full of tumors. Cancer happens because our immune system isn't up to the task of properly repairing hits on our chromosones. It's also the reason we age. We're a pretty poor design in many aspects. That's not to say enviromental conditions don't exacerbate this. You're certainly correct that until we can do something about our primitive immune system, it's best to try and eliminate unnecessary hazards. Therein lies the rub. Unless you want to sit in the corner and not touch anything your whole life, there will come a time when there's a tradeoff as to acceptable risk. >And our society is a gullible collection of simple minded idiots.

When dealing with a composite source, the huge advantage of a modern set is the comb filter. Many sets now have 3D frame-based filtering, and chorma/luma seperation has gotten very good indeed. Blows away any vintage set. I know what you mean about delivery systems that have the living daylights compressed out of them. People look like they're made out of clay. The high frequencies remain, though, so I'm not so sure a gentle roll-off would make things look better. -- Tim Mullen ------------------------------------------------------------------ Am I in your basement?

Message-ID: Date: Tue, 14 Mar 2006 12:50:33 GMT On the other hand, I've got a Heathkit, which is actually a Zenith System 3, that's almost 25 years old. It's still in our living room and we still use it every day. Oh, I figure someday soon I'll buy a big screen HD set, but not because there's anything wrong with this one. In fact I love the big console cabinet. Zenith did indeed have a reliability problem back in the 1960's. After everyone else had migrated to using printed circuitry, Zenith kept advertising their "hand wired" chassis. Like many new things, the public, along with technicians, didn't care for the new PCB design, thinking it was cheap. But the result, while other sets were becoming more reliable, Zenith was lost in the 50's and was plagued by bad solder connections everywhere. It even became a joke, to "kick the Zenith" to make it work. If one were to totally rebuild and resolder the set from the ground up, they actually weren't bad units. Zenith had another problem during the late 1980's, with their picture tubes. The CRT would fail, not a matter of if but when, and that was the end of the set. Now THERE's one to hang onto, that'll be rare someday -- just find a good CRT for it. Zenith's saving grace, and probably the only reason the name is still around, was their being purchased by Lucky Goldstar. It's a bit of a shame that the last American company to build TV sets fell off in this way. Now it all comes from the far east; but that's another subject. Of course my Heathkit, I've had people try to tell me the set is foreign made -- I tell them it is definitely American; I built it in my own home! -- Gary E.
