Also 4.7k nfb resistor and 2.2uf presence cap.

Thanks for all that information Guy.
I would expect the trimmer/capacitor on the pab board to be connected to the treble pot only when the pab would be engaged.

Did you find out by any chance what are the values and the role of the capacitor and the trimmer on the pab relay board?

Very cool!

Here it is Marcus

In the classic reverb signature looks like that the 220k resistor is eliminated.
Any ideas how this would affect the sound?

You can find black vox grill cloth on ebay.

You can use even a four wire cable for three footswitches and their leds.
That's how i have my amp and it's working fine.

To my ears sample number 2 sounds slightly smoother.
Both samples definitely sound great!

This should work.

Thanks Roe,I'll keep that in mind.

That's exactly what I was looking for.
Thank you Colossal.

Hello -
I'm pretty sure that i had read in a post a few months ago the actual resistor values for the two rock gain structure switch,but i can't find it now.
I'm building a 50 watt wonderland and i would like to implement that switch.
Does anyone still have that information?
Thanks,
Dimitris

You can use the 4 wire cable to operate three switches and their leds.
Check attached file.

I have bought pcbs from pedalpcb in the past. Excellent communication and top quality pcbs.
BOM and schematic are included in the building docs.
Aionelectronics is great too.
