yup....I can touch the tubes and it cuts in and out. I will check it out and give it a whirl.

Going in….
The brackets for the preamp tube board were pretty loose. Tightened them up. Solder spots look okay?

Not going to lie, this board gives me all sorts of red flags.
Lots of potential sloppy solder bridges. Seems like at least 2 traces are broken, or cracked.
Apparently they lived by the ethos, bigger the gob, better the job.
Also, these had a production defect, that was fixed with rework.
Like I said, many red flags .. troubleshooting nightmare. Find a replacement, you'll be happier.
Edit - not saying it cannot be repaired, but not for cheap, either monetarily or with your own time.

Hard to tell from this pic, but it looks like a few of those caps are bulging.

it's fucked up. no hum but it's not full bore. gain is weak. now I touched a tube and everything cut off...(power tube) so fuck it.

And also I’m admitting defeat on my amp. I tried reflowing the solder on some spots. Nothing complicated about that…just heat and let go. Anyway it’s just not right. Going to get some deoxit and spray the fuck out of everything next. Then it’s hammer time. Also have some matched new sovtek 6l6’s to try if necessary. Not sure why the gain is low. Also the lights on the pedal act wonky as well. I was tapping on tubes with a piece of wood listening for anything like microphonics or static when I discovered the issue with the power tubes. So irritating.

just a heads up ..... you shouldn't have to reflow the traces themselves ..... unless there is a break you're trying to fix .....
just reflow the pads ( holes ) where the parts come into the board
my bet it's those cheap ass ribbon cables connecting the pre amp board to the main board
how much do these go for ???? got to weigh out if it's worth the hassle at some point ....

I was thinking the same way . Pull the ribbon connectors , spray with Deoxit , reconnect .
It's cheap and fast .

If deoxit doesn’t do it I’m done. I literally have less than two hundred in it and I have had it for awhile so…
