So I got a KF-50....and it's blowing the 3/4a fuses

What does that mean?

I have some mismatched old Mullard XF2s in it 4ma apart. I tried setting the bias to 30ma. Anyone help?

Thanks! Jim

Blowing the HT (high voltage) fuse often means that one of your power tubes is shorted. Try pulling the power tubes and try again. If the fuse holds, set the bias pot to the lowest setting and try one tube at a time. The tube that causes the fuse to blow has a problem.

He is always there for me. I need to put him in my will.....

Power tubes will blow the 3/4a....it's them...problem solved.

Thanks to everyone who helped me!
