Awesome! I think things are working, the amp sounds great, no scratchy pot , no change voltages or current with higher volumes. I cannot thank you enough Beez! So now after I enjoy this for a bit Im moving on to perhaps the 4-4-0 push pull amp! Thanks man

So now with bias pot at 0R. Readings such:

Va 372 V
Grid 0V
Cathode 26V

No DC on tone stack side at all, each tone stack cap reading Dc voltage across also.

After adjusting the bias to about 45mA the Cathode reads 37V. So just to be sure that things seem ok now…my bias pot is now at 500ohms and the voltage is 37V across it with 45mA of…[Read more]

Oh yes I did know that Being silly. Start getting things backwards after hours of numbers back and forth. Ok so let me check my treble capacitor and make sure its working. Ill get back to you on the voltages. Yes I thought the grid should be 0V.

OK So I think I might have the problem. So the Treble Cap is showing only 8V DC across it, but then has almost 182V DC from the Tone stack side to ground. The mid and bass show the opposite. The show around 130V DC across them, as you mentioned was normal, and then about 5V DC to ground. So suspecting I should checking wiring and replace the…[Read more]
