Can anyone tell me the difference between a 25K7191 and a 25K7193?

I had a working, although not very well, 25K7191.

After recapping it, the 2.7 Ohm resistor was open. I replaced that, and now it is blowing fuses. I will check C36 and the HOT. I know I did not put the mica insulator back on when I replaced the HOT. That has me worried because I cannot find it now.

Nothing to really speak of.

Absolutely fix that first... that will blow a fuse in a heartbeat.
"Insulator" means just that, the HOT should NOT come in direct contact with the heatsink.
