Tube Amp Archive

Agree, cutting trashes even carbide blades fairly quickly. Drill bits as well when drilling for eyelets and turrets.
I use 1/8". As mentioned, be very wary of the dust from machining.

I've gotten G10/FR4 from McMaster-Carr. I don't know how their prices compare to others. Lots of sizes to choose from.

Built a head cab for this amp, yet to be finished (probably just amber shellac) an will use the combo cab for a push pull amp with a little more juice. Yet to be decided.

Thanks Phil

Thanks, and big thanks to pompeiisneaks

Beautiful work

So great to see you back Tom. You've been missed.

I wrapped the reverb driver plate around the tube socket as recommended and it made a noticeable difference in lowering the background noise. I have a couple of Rocket Reverbs that I will try that lead dress on.
Adding the the bass pot jumper didn't seem to do anything so I removed it.

Thank you for these edits , corrections, and suggestions. I never did quiet this amp down to where I like it so maybe now I can! Tone wise, I love the amp. Just too much background noise. I use it every day.

His songs will live on. We had Big Pink on auto repeat for weeks on our KLH turn table when it was first released. Same for albums that followed.

Made a bunch of changes and the amp is working now. The grounding was changed per Martin Manning's DR suggestions. V3 wiring was flipped around a bit. The first dropping resistor went from 10K to 12K lowering the voltage for B+C and B+D. The 47K resistor that sends some signal to ground before the 2...

Actually, really glad for the impetus to upgrade the grounding as it will be an improvement once I find the problem. Just being lazy. I should also change the standby switch configuration while the hood is up, or just get rid of it.

Grounding updated. No change. Will dig deeper as I must have missed something somewhere. I have a few ideas.

Looks like a 10 string Puert Rican Quatro...

Martin... I made most all of the changes that you suggested from your beautiful DR build, with the exception of the reverb section, which I'm still working on. It's going to take some rerouting and time but could be the culprit. I'll plug away at it and report back. Thanks.
