Tube DIY Asylum

I put them from the B+ tap to the film cap supply, and then I wired it to the anodes.

So, you blocked DC voltage to the anodes? But, didn't that show in your voltage readings? I thought they were ok?

I know, the voltages were still there. But the signal was not being passed. Where was it going? I dunno. I guess the signal must have been going into the big film cap. regards, Dak

  What'd I tell ya? look for subtleties in the assembly.
  
  Don't feel bad though. Troubleshooting something that has never worked is usually harder than troubleshooting something that used to work just fine.
No, he had a cap on the plate, blocking the AC from developing - Chip647 19:27:06 12/11/14 (1)
The signal on the plate was eaten by the cap. More common mistake is using a bypass cap on a cathode follower bias resistor. It is fun when these problems get fixed and the silence is replaced by music.

  It was funny, I told my boss at work that I had this amp that was not working and he told me he had a hammer that might fix it. I told him I had 3 hammers and then he said he had a bigger sledge hammer. And then he asked if I was going home and I told him no I was going to work on the amp. And the next thing I did was look at the driver tube power supply and I realized that I had wired it incorrectly. I then rewired it, and presto, bingo, shazam.... it works and sounds great. thanx for the support. Dak
That's right. He said the DC voltage readings were ok. - morinix 18:38:50 12/11/14 (0)
What gives? Well it's fixed anyway.
