I powered up the supply TR with a variac. All's well with the TR. AC output is about 15 volts. I then hooked up the rectifier and the field coil and slowly powered it up. it works but the output DC voltage is about 6.7 volts DC with 15 volts AC in. Not very efficient! I think the speaker would certainly work, but not up to full potential. I suppose I should hide a silicone full wave rectifier in there somewhere. But then, that may over tax the TR. should I also put a resistor in series to more closely match the deficiency of the copper oxide rectifier? those of you with experience in these rectifiers, I need your input! Thank you.
