Amp Issue

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Guys,

One of my builds has developed an issue. After some time in service, one of the channels goes 100% with the volume at 0%.The other channel sounds slightly distorted.

I do do have CCS feeding the plates of the first stage. I can't imagine a POT failing like this or it would be that way when it's cold. Could I be getting imbalance due to not enough isolation between channels. I presently have a modest amount of resistance between the b+ each CCS. I have considered diodes to isolate the B+ for each CCS.

Any thoughts?
