I came back to this project recently and did some more wiring and soldering.

I ran into a problem I think it could be around the EF86.

The unit doesn't pass audio.

When I play with the spare leg of the drive it gives me ground hum and lets me check the controls which function as intended. Tapping the tubes I can hear. Tapping solder joints  around the 86 I can hear but I don't think it's passing audio. I've tried with two different 86, same problem.

Everything is fine upto the 86.

What B+ voltage should I be reading on the 86 line?

Any insight or thoughts would be great. Am just scratching my head at this stage as there is not much in this to go wrong.

Audio passes now.

My main issue is that annoying fizz.

Is this an inherent characteristic of a poor 6as6.

I've grounded the hell out of this thing 😂
