[Amps] help with Collins amp ID

[Karl-Arne Markström]

The descriptions fits in on the Collins 204H-1 servo-tuned amplifier.
It is the servo-tuned "brother" of the two-channel 204F-1 which appears to be more common.
Pictures of both amplifiers can seen in the document http://www.collinsradio.org/Collins_1959_HF-VHF_Ground.pdf

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.
