Mainline BIAS Issue

[Mike V.]

I just notice that 2 lends on the C side board takes a little to turn on

On C side, you have resistors from the center lug going to 3 and 8 of the tube socket. This is supposed to be 2 and 8.

I knew the issue was down there! But couldn't find where, That's the problem of building an amp at late night hours.

That for sure resolved the Bias issue. Thanks!

The final result a clean pure delightful sound!

Doc, Paul, Mischa,

Thanks for your help! A tired eye is a dangerous thing lol hopefully all my soldering was clean and well done. Got a clean sound.

Delightful sound!

I would also resolder the middle leg of the MJE5731A on the "A" side, as it looks like the flux hasn't flowed out of the joint completely.
