Replace V3 or swap it. Were did you get those blue capacitors? 220uf/330uf and the 10uf 160v. I've been looking for some of those.

If they're the same ones as on my build, look here:

Those are High Temp (also more expensive) versions... and the datasheet shows different markings.
You can find the ones I used here:

I hadn't noticed activity on this thread. The blue caps are are distributed by Vishay. I sampled directly from the distributor. I will make a concerted effort to record this amp semi-decently. Good luck with your project.

Hey axeman, were you referring to the hum? That issue has been resolved (OT-PT coupling). I have had a few different valves in v3 and no effect has been heard.
