AMZ Sixties Fuzz... found out.

Synthbum	AMZ Sixties Fuzz... found out. Okay - If anyone else decides to try one, they'll want to know. That obscure SK3005 (Q2) is PNP Ge, not specified as such on the AMZ schematic (currently unavailable). The SK3020's (Q1 & Q3) are NPN Si small signal, available from Mouser. No designer here but I expect the Ge transistor at Q2 is there for it's distortion characteristics. Both transistors indicated are Harris manufacture. Looked them up using FLIS, the Federal Logistics Information System, a DOD CDROM database used where I work. Plenty technical specs listed but not hfe. Just a little FYI. - synthbum
