Can anyone tell me what the structure is switching in all 3 positions? I guess it is a DP3T On-Off-On of sorts. and I can see tha in 1 position a 680p is on 1 side engaded and a 2200p on the other side. But what other components are involved?
I only give negativ feedback and y'all love it! PCB shop
The J201 is the booster side on the front end, The schematic in the goop is nearly identical to Box of Rock. But it runs with 27 volts if I remember correctly. I will try to build a box of rock without tonestack and add the TS traced up here to check the results. The Box of Rock's gain section ( 1st stage source pot) will be 1k or lower value with a bypass to see if it works.
