> 100 va at 400 Hz might be for blower(s), 28 volts 35 amps to do 1 KW input
to the PA? Seems awfully close, especially for the power margins built into
the RF section. Leaves nothing for inverter inefficiency.
==============================


The information <115 VAC 400Hz, 1-Phase @ 100 VA, and 27 VDC @ 35 Amp> comes
from TOs and TMs.

You're correct about the 400~, it's only used for the blowers and some tune
motors. The 28V is used to produce HV.

1 KW is anecdotal. This RTs output is specified at 100W av CW, 100W av AM
and 400W PEP SSB.
