thanks Stephanovitch!
...for future visibility i've uploaded the image here on the forum, hope you don't mind

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?

Hi everyone

This is the best i can do with the secret part layout

There is some missing parts, all transistors are the BS170, i guess the 680nf and 4,7uf caps go with some source resistors

If anyone did some further research please post

Cheers

It’s really bs170?
Where j201 from picture?

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.
