Darin, I wire and jumper the on/on R/J like #183 and the PAB has always worked. I was always under the impression that if you wire it like you have it, you have to use an on/off/on switch. In the layouts, 102 is wired like 124 which uses the on/off/on which places the PAB mini switch function at the R/J switch. Look at the #183 layout to see the differences.CHIP wrote:Darrin, I used an on-on switch for R/J switch. Looks wired correctly. Faulty relay?

Also, the bass resistor values isn't an issue, in my "004" I'm using a classic stack with 1.8K tail and it functions fine and you proved it's not the relay board when you switch them and found the same result. I'm almost 100% certain it's the way you have it wired.
Aaron did this nice layout with the PAB relay configured as you have it, maybe this will help.

That's weird. For my #102 build I'm using an on/on for my Rock/Jazz and have it wired just like 102/123 (as per my layout). Everything seems to work. Of course I might just not know what it's supposed to do when it doesn't work.ToneMerc wrote:Darin, I wire and jumper the on/on R/J like #183 and the PAB has always worked.

It looks like the white and purple wires going to the relay are backwards.

I don't mind helping anyone and I learn something new every time I build one of these, there's so much to learn with all the different circuit variations. Also, I like look at other builds as well, there's always something to learn. I've been forunate enough to do a few builds and along the way, even more fortunate to have help from guys such as Tony, Brandon, Gary, Andy Fuchs and others. I try to share what I do and along the way, maybe give something back.dcribbs1412 wrote: I for one feel that most here that have successfully built a few of these complicated amps has the experience to guide others through it...
Hopefully gaining more experience a long the way.
Thankfully you and others here also have the patient to help.
Appreciate your time
