No. If you need help finding the cause & fixing it, post a request for help in the Troubleshooting forum. Include clear detailed pictures of both sides of the board. But first, do your due diligence and perform a thorough visual inspection checking for incorrect parts, incorrect orientation, bad solder joints, shorts, etc.

Thanks.. Found the problem 1k fuzz potentiometer was garbage.

Just curious, what hfe are we shooting for on this Ge?
I have tons of Russian/Soviet mil Ge that can fit this, so may just socket and see which sounds best.... just curious which range skreddy shoots for, and if you all are altering the R10 5.1k at all?

Thanks

I did not remove and test the AC127 in the production pedal I bought. All of the AC127s I've come across are leaky. The leakage lowers the effective gain (not hfe) of the last stage. Different Ge transistors will sound different in this pedal. Best bet is to audition a few.
