Re: Question about HV transformer [1 Attachment]


 

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
