Need help w/ Bando xformer identification

Hello

I have a power transformer I would like to use for a project. It is from a h/k hk795i. I have the voltages (5.86, 36.2/72.6). I need to know the current rating for this hulk so I can do some caculations. The stamped info if below. Thanks!

BANDO
5584-701515 <-this is the p/n refed in the h/k service manual
BD21A3-0015
BE11-HCQ

btw -- the amp contained 2 pair 2sc3281/2sa1302, if that helps define a current range. thx again.

I have found some more information that may help. According to the h/k unit service manual, the whole h/k recvr drew 240W(330VA). Now, would that make this transformer approx 400VA max or so ???

My ultimate goal is to use this transformer as part of an dc res/cap power supply for an EDM machine (used for machining metal). However, to do the calculations, I need to know the approx amps of the transformer (Imax in my formulas).

Even guesses are welcome

thx folks!
