Ah yes. I should have remembered that. I have most of an AN/TRC-1 and the manuals here. 
I also have several of the 200 watt amplifiers, the AM-8/TRC-1, NIB here.No power supplies 
for them though.

Those are interesting amplifiers, to be sure. They have a pair of 4E27s in them. They are 
easy to convert to cover either (or both) 6 meters and 2 meters by the use of two capacitors, 
ony. The later 5-125 can replace the 4E27. I have always considered the 4E27 to be a rather 
"delicate" tube. Not much support for the plate connection.

Reading the history and deployment of the TRC-1 is very, very interesting. Apparently, one 
thing it accomplished was a very reliable RTTY network for Eisenhower during and after 
Normandy. I think the system was first tried out in Sicily, in fact.

As I remember it, Link had a lot to do with its development and implementation.
