I Killed my Kay 720, I'm mortified. Help, please.

oooooooops! time machine needed BEFORE he fried it!

sure aren't many (surviving) Kay 720s either......

That was pretty funny, I hadn't caught it myself either. I just thought earlier today when I saw it "geez there are two Regis out there with a Kay amp".

Guys, thanks for the replies. So, to be sure it's the PT I should disconnect it completely and try it free of the circuit? any other tests I can do?

No idea where I'm going to get a replacement for this. No idea what the secondaries are like. The code on the transformer is 32A0006, not sure of the make.

Should be fairly common Regis, do you know what the voltages were? You can measure the size/mounting requirements, most power transformers for tube amps have the required 6.3v & 5v coils. Match up the mounting and the voltage/current for the power tubes and you've got it. If you can't get exact you can get pretty close. If the voltage is too high you can drop it using the zener diode trick on the high voltage center tap.
