You are correct: 805 modulators. I had forgotten.

I'll try to find that photo and if I do, I'll post it here.

My T-350-XM as grey.

There is some fellow in, I believe, California, who has a large collection of T-350-XM transmitters and parts.

I have his address here somewhere, but haven't seen it in years.

Ken 
The T-350 is a very well built xmtr using very good components . I have the preamp for it and unfortunately mine was missing all the tubes. The manual shows a pair of 805s in the modulator.  My cabinet is green like the one pictured at the sale. Most pics I have seen of others who have this xmtr the cabinets are gray. My understanding is those were used on Navy destroyers .
The green ones I presume were used by the British in the Pacific, Burma I believe.

Ken , would love to see that pic you have of the T-350s in the army instalation. 

Tnx

Number 42 is a TechRad T-350-XM, one of the finest transmitters used in WWII.

It has a pair of 813s in the final stage, a very wide range antenna coupler in the top section, and is modulated by a pair of 811s.

It used an external mic preamp in a separate box somewhat like the BC-610.

It includes a very stable built-in VFO. Power supply is in the bottom section and is not obvious in the photo. Power supply has two chokes in it, one a swinging choke. That choke failed in mine and I replaced it with a standard choke. Uses 866 mv rectifiers, which I thoroughly despise. I replaced those with 3B28s.

I got a brand-new one through MARS and loved it. I gave it back to MARS when I left Missoula, Montana in about 1979.

The state MARS director traded it to a member in California for a B&W T-368.

I would rather have had the TechRad. I sure wish I still had it.

I sure hope that whoever gets that appreciates it. I heard that most of those manufactured went to the Brits in Africa and were mounted in trucks as part of a mobile comm station.

Looks like an early Kahn SSB demod!
