As a starter, I calculated the secondary for a replacement pt should be around 225-0-225. That is taking the rectified voltage and dividing it by 1.414. You also need to make sure the new PT will handle the current of the power tubes. Also, you will have to add a new rectification circuit to...

Yeah, the stock power supply circuit looks exceedingly over complicated. You still have a transformer in the mix, and it’s fairly standard layout on the secondary side, but the junk before the primary just seems a little excessive when it comes to a power supply for an amplifier. Or maybe I’m...

Almost seems easier to get a power transformer and build a power supply :ROFLMAO:

That sound very interesting! Imma hafta check that out! I've had a AB763 project on the hold for a while. Working out a dual channel AB763 and some kind of high gain modern metal type circuit. Was basing most of the clean channel off the Hoffman 1 channel AB7673. I've built the P1EX, SEL...

When I started the AX84 site was still up and active. That was a great resource. There are schematics for SE, PP, pre amps, power amps and others like parallel SE. I know there were a site or two listing the resources or a copy of the dead site. I used a cake pan for my first build, an AX84...

Got any plans for a Jets to Brazil pedal run? :D

That color on that enclosure is friggin gorgeous! Nice work!

I’m not so sure it would be the pedal in particular. The other day I was playing through a high gain pedal and heard an Asian lady preaching. Bypass pedal, no preaching. Next day a couple of guys talking about religion, bypass the pedal, suddenly I lost my religion😜 It just makes what is...

Pretty sure the extra middle hole is there for cross-compatibility between the different transistor package types. Should be able to use either hole in the middle/bottom for the base.

I got a +1 in my passive aggression skills, reading it! :p

That's some fine work! I really dig that look for the PCB! It looks like a nice clean layout! I'm using the same power connecters on my power jacks. Makes it so much easier to remove the whole thing, plus the power jack can be wired outside the enclosure!

That is some nice clean work! I imagine it sounds Awesome! I'm getting the itch to pull out one of my gazillion amp projects/builds.

I been waiting on a Fuzz Master General clone!!!!!!!!!!! Woooooooty tooot!:love:

You should be able to connect the In and Out and the 9V and Ground. Leave the switch side GND and SW empty.

I hadn't ever seen the heater wiring done that way! I'm stealing it for my next build! Looking clean! Makes me wonder why I've not built a kit yet!

There are some good Pedal diagnosis videos on Youtube. These can also help familiarize you with the processes others use to find the where there are issues. Pedal Fault Diagnosis Search If I'm having issues with a circuit I will often times audio probe the circuit if I am getting partial...

What's going on with the input wire coming from the switch to the board? Almost looks like it's connected to the Anode of the LED in one picture..

Is it the common practice to ground the shield at the "signal source" side of the wire run? I've heard that in tube amp construction, and have used that technique when running shielded wires.

I've used the rustoleum clears several times. If you get the 2X Clear or Professional Clear, expect it to take a long time to cure. I switched to the rustoleum Automotive clear. It dries much faster as it's a different type of paint, I believe Laquer over Enamel type. Rust-Oleum-Automotive...

Friggin awesome crackle! Is that the stuff you spray on then blow air over it to get the crackle effect?
