Hi all,

here is the BC108 Fuzz Face from 1969-70 Hendrix era.

Anyway I've got ready to transfer PCB and schematic, but the size of the PCB it self is a problem. I've checked the size of the image in photoshop, and it says its width: 17,5cm, height: 10,83cm; which is not true. So if anyone got the size of the PCB itself would be really grateful!

61,5mm wide and 42,5mm in height. Measured from my board which is a repro from ten years ago or so. Should be close enough.

That's a layout for a germanium PNP Fuzz Face. It will work, but you have to be careful about the orientation of the electrolytics.

The silicon version has the poles of the electrolytics labled correctly for an NPN Fuzz Face . As Dallas-Arbiter designed that board with BC183Ls in mind, the pinout for the transistors is a bit awkward for BC108Cs. Dallas-Arbiter used to put insulation on one of the leads to prevent them from shorting out..
