Can anyone shed any light on a Collins auto tune amplifier, made for the Air
Force? Looks to be about 2-32 Mhz.
This baby appears to weigh about 600 pounds, runs a pair of 4cx1000a's (sorry
Rich, no handles) and has a tube driver stage. Vacuum rectifiers (probably
3B28's but not sure) and 4 oil filled caps in power supply. I did not see a
modulation transformer, but it was not a very close inspection. A single 19
inch wide by 6 foot rack, maybe 20 inches deep.
Data on the plate is: Collins Radio, AM-2104(XW-1)/GR, Part 522-1452-005,
Contract AF30(635)4504. It has a single digit serial number.
A search of the web has not turned up anything. I very much appreciate any
anecdotal info or data available. 73 bob de w9ge
