Looking at the original circuit, all the coupling caps are different. From left to right, .01uf, .22uf, .01uf. I think I would pull the two .1uf caps and measure them, or just replace them with .01uf caps. Maybe just for one channel first.The coupling caps?

Lol... yes def a build error... lol...
Coupling caps are weird to me to be sure but then its all alien to me. Sound in to exit there is the .1uf on pins 1 and 6. same tube pins 3 and 8 lead to where the .39 and second .1uf are joined. Then there is a double barrel coupling cap unlike the little rectangular jobbies at audio output.
(Waves hand) you will not see that all solder points look like a 5 year olds face in winter...

I also need to borrow a +/-250v lead from somewhere... recommendations? Top left corner says 258v... but I dont believe it is... that or my meter is funky.
I don’t know what you mean by this, or by ‘250V lead’ either. Why don’t you believe your meter? What does it read?. Then there is a double barrel coupling cap
I just meant it is what I pictured, unlike the others that look like now-n-laters.
I need to power a small board to operate the magic eyes as VU meters, which calls for 250v. It is inconveniently placed but I believe read 320 DC, which I found confusing. Will test again later today. Now off to work.

So I think it's a fairly clean build. Everything works to be in order. All of the resistors are correct, nothing is rubbing or touching.. there was one thing that next me throughout this bill

So the printed board wants a 5w 1.5k ohm resistor shown in similar builds but absent from the schematic
Could that be part of the issue?
