What to make with +/-76V transformer ?

[lordvader88]

I salvaged a Kenwood audio-video surround receiver. And it powered up and looks fine inside. So I have a big transformer with +/-12V control rails, +/-76V with bridge rec.'s rated for 2.8A unheat-sinked like these, 6A when heatsinked. There's also relays controlled from a STBY trans, for the  +/-76V rails.

So that whole area of the board can be sawed off and be a great and safe supply , what should I make in the way of lab power supplies or something useful like that?

I also have a rotary encoder, another really nice circular dial, a nice LED/display.

And I found the whole schematic and it's great. So I have all the details on the chips and controlling the LED display for  other stuff I guess., And everythjing else in there.

PSU is on page 13


There's 4 relay's total, and also a +/-46V winding. I haven't found the current rating. I found the stereo schematic from looking up the transformer 1st.

I could load test it, but so far it's too big for my imagination and needs.
