RH amp problem solved

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Thanx everyone for your suggestions in trying to help with getting the amp running. While no one gave the exact solution I would like to think that with your help and suggestions I stayed on the issue long enough to figure it out. So, without further ado , here is the problem, and no snickering please...
What was the problem? When I rebuilt the amp to RH configuration I kept part of the power supply to the driver tube from the previous configuration. But to get it to the new driver tube anode voltage I needed to have 100k dropping resistors to the 12ax7 plates. And foolishly instead of running the 100k to the 12ax7 anode I put them from the B+ tap to the film cap supply, and then I wired it to the anodes. I went back and put the 100k resistors from the film cap B+ to the 12ax7 anodes and Voila, it works and sounds great to boot. Thanx again everyone, Happy Holidays, Dak

The signal was being bypassed. - Ralph 09:58:55 12/12/14 (0)

No, he had a cap on the plate, blocking the AC from developing - Chip647 19:27:06 12/11/14 (1)

That's right. He said the DC voltage readings were ok. - morinix 18:38:50 12/11/14 (0)
