Title: Was working, now no sound?
Post by: bach on August 13, 2016, 08:02:17 PM
My Dizzy 30 was working perfectly, but then I tried to add the Dana Hall VVR. It was installed between the standby switch and pin 8 of the rectifier tube. I was working when it was late and wound up wiring the VVR's B+ in and B+ out backwards. The amp was working while the VVR was wired backwards, but the VVR didn't change the amps volume.

I found my error the next day. Wired it correctly and got NO SOUND what so ever out of the amp. I then pulled the VVR completely out and wired the amp back to original (Standby switch to pin 8 of the rectifier tube), but still I have no sound. The tubes are lighting up. What else should I be checking for?

I checked my filter caps and they are good. I'm reading weird voltages on the power tubes, but I'm suspecting the output transformer to most likely be the problem.
