Until I told her it was for a Hammarlund HX50 Heterodyne oscillator. She said, "Let me see.....what frequency do you need?" "38.660 MHz" "MMmm that is a third harmonic......", "Yes we have that Hammarlund HX-50 crystal. It is a third harmonic and is $19.95 and can ship on March 28th." "You don't sound like a receptionist to me. " "We dont have one. I am in sales........25 years........." They apparently handle and welcome armature radio crystal orders. I could have sent the engineering department an oscillator circuit (but they already had the HX-50 documentation and many more) so they could help select a proper crystal. Now I am no crystal oscillator expert. So I greatly appreciate this companies friendly help! If this crystal restores the output of the heterodyne oscillator to its former frequency and amplitude I will be ordering more. If you call ask for Barbara ex249 and mention you saw this.

I used the Johnson ceramic sockets (square type) that did have some holes which lined up with the ones in the bottom of the tubes. I mounted the sockets under the chassis FLUSH with the bottom of the chassis. I pressurized the chassis with a 4" boxer type fan mounted under the tube sockets. This fan was one of the high speed types that could move lots of air. I also mounted a pair of the same type of fans next to the bottles on the top of the chassis, blowing air from outside into the chassis past the tubes. The air flow went through the base holes and around the glass bottle. This is similar to the way the SB220 linear was build, as with many HB amps. The tubes did not suffer any heat effects, while the pair ran near the legal limit. BTW, 4-400's work ok in GG, but they like more HV than their triode counterparts. While a pair of 3-500's work well with 2500v, the 4-400 likes more like 3300-3500v to get the same output and IM figures. So your tank circuit will have more "L" and less "C".

I have seen the sockets raised a bit so that the filaments get cooling. > Just wondering if the 4-400 would work that way as well? Any experience > with this? My recollection from Eimac tube spec sheets is that there must be forced-air directed upwards from the non-tube side of the tube socket and there are specifications for flow rate and pressure. Both the 3-500 and 4-400 (100 watts less plate dissipation) call for 5 v at 15 amps (IIRC) on the filament and that is a lot of heat. I don't know if the 3-500 is pushed closer to the limits on this but Eimac made a special socket (and chimney) for the 4-400 but many ARRL handbook amplifiers went for a much simpler socket. And, the Johnson Thunderbolt (I had two of them at one time) used a simple ceramic socket plus an under-chassis phonograph motor type of fan to blow air up from the bottom as well as an above chassis fan motor to blow more air around the pair of 4-400s for a 1 KW DC plate input level (with dull red cherry glow on cw carrier and a little less glow on SSB voice). Beyond that, if you are thinking of running 4-400s instead of the 3-500z, you also need to worry about bias voltage a little and you would have to resolder the socket pins because the 3-500 is a triode and the 4-400 is a tetrode (need to ground the screen, as well as control grid). But I have run 4-400s in GG in a homebrew amp in the past. > Doug N4IJ > > > Article: 101836 of rec.radio.amateur.boatanchors From: "Caveat Lector" References: <1142053122.558738.189430@i40g2000cwc.googlegroups.com> Subject: Re: Info for pre-war boatanchors Message-ID: Date: Sat, 11 Mar 2006 11:24:06 -0800 Maybe try URL: http://ac6v.com/antique.htm#AHR -- CL -- I doubt, therefore I might be !

My home brew linear started these tubes up with a power resistor in series with the primary of the filament transformer for a few seconds, which was then shorted out by a relay. A transistor r/c delay circuit did the dirty work. This lets the tube filaments preheat a bit before applying full voltage.

Also thanks for the link to your web site, plenty of wonderful info! One question please - I have 8 type 3-500Z which have not been used for 20 years. You mentioned operating them at low plate voltage and positive grid voltage, so that the plates show color (for gettering action). What range of plate voltage/ grid voltage do you recommend, and what current limiting resistor would you suggest in the plate circuit? Do you use a current limiting resistor in the grid circuit also? I plan a test fixture to recussitate the 3-500Z tubes before risking them in an amplifier. 73, Ed Knobloch w8ji@akorn.net wrote: > As for cooling, seal cooling is critical in glass tubes.
