Thanks Lou. I did a search based on component ID's, and found it was a
LPA-2 amplifier, from TMC. Two 8163 triodes.
Unfortunately, the manual lacks the schematic, but the power supply is
quite similar to LPA-1KC model (TMC also).
Many thanks

Sounds to me you would get around 3300 volts DC after a doubler
rectifier. ?The .3A is probably a CCS rating so at ICAS that¡¯s probably
good for .6 amp. ?In an amplifier running two 3-400 tubes that would be
an input power of about 1980 watts and probably 1100-1200 SSB would be
my guess. ?Lou

GA, I took out the HV transformer (from an old commercial PA, burnt
beyond practical repair, which I guess was for twin triodes 3-400z
style, at least based in the sockets used and the filament transformer
which is a 10 VAC CT, 15A one).
This HV transformer has two primaries (115 VAC each, 50-60 Hz), and one
secondary which states 1200 VAC, 0.3 A DC Doubler
How should I estimate the transformer ratings, in terms of power
capabilities?, I don't understand the meaning of that stated current
value.
TIA
