Here is my version of this Screamer designed for SMD technology. Pots and switch are on the other side of Pcb, DC jack and input/output jacks are mounted directly on 1590A housing.

I think the resistor values R10 and R11 must be swapped (R10=1k, R11=220). You can once again verify the original TS MINI?

I don't think so.

Thanks for the answer.
Strange that the developers have swapped value resistors. Here for example the old original scheme.
See R108 = 220 (for tone) and R111=1k

This is a thread I missed completely. Thanks Apollo! Also thanks Ixide for noticing this error. Makes one wonder if someone made a f-up with the BOM.
Sorry. Plain out of planes.

or the pick and place machine had the wrong reel loaded that day.
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

I think you will find there is no Knob as such, the shaft is the knob. So if it's broken/damgaed then you will have to replace the whole pot.

It's a 20K pot made by Alps.

Check Digi-key or Mouser for mini pots like that, standard PC mount.
