+No. I may be dumping these transformers.

If they have enough current rating, they maybe usefull for a 40VDC
supply to power a 100 to 250 watt amp?

After I made a dimmer using some of these transistors, I realized I had created
a high current DC amp, so I applied half voltage (bias) and fed a capacitor coupled
AC input to the base and took a capacitor coupled AC output from the emitter
and now I can amplify audio. I made a duplicate of the first, and now I have
a stereo class A audio amp. I might take those transformers and create an unregulated
40+ volts DC to power this amp. I need to redesign the input circuit...

Makes some heat with a 13.3 volt VCC. You need to draw some current from the
transistors to develop a decent voltage drop to get clear audio. I'm using
light bulbs as high wattage resistor. I had to make two separate bias adjusts
or it would have ended up monophonic.

It's a FrankenAMP! (TM)

Can I make class AB by making splitters on toroids like is done for RF amps?
I only have large NPN transistors. I've got a lot of them, and quite a few
old computer power supplies for resistors and capacitors.
