Hey guys. I just finished up a Ceriatone OTS HRM with Classictone transformers. I'm trying to work out a few kinks. The main one being the overdrive volume is way low and sounds like crap. I started checking voltage s and noticed that pin 1 on V2 was way low. Here's what I'm getting on V2:

Pin 1: 90
Pin 3: 3.8
Pin 6: 224.5
Pin 8: 1.7

Can you guys point me in the right direction on what to check? I'm relatively ignorant when it comes to this. I've only built one other amp before. So explain it to me like a 5th grader. Thanks for any help!

Ok, it looks like the tube I had in V2 had an issue. I swapped it out now I'm getting the voltages below. The amp still sounds horrible. Not a lot of volume on the drive channel and it sound nasty and fizzy. Any help?


V1

Pin 1: 207V
Pin 3: 2.04V
Pin 6: 210
Pin 8: 1.95V

V2

Pin 1: 214.4V
Pin 3: 2.03V
Pin 6: 217V
Pin 8: 2V

V3

Pin 1: 184V
Pin 3: 86V
Pin 6: 373V
Pin 8: 86V

If your clean is OK then you just need to double and triple check your OD wiring right back to the relay.

Also your PI voltages are way off. Which would indicate to me your clean isn't going to be OK either. I'd sort that first.

Thanks! Yeah, I'm going to try to get the PI right first. I'm going to try a different tube first and then go from there. The clean isn't great, but it's much louder than the drive. If the tube doesn't fix the PI problem where is the first place i should look? Thanks again!
