MOSRITE FUZZRITE silicon schematic ea8ac86fd1b6

After spending some time on the germanium Fuzzrite, time for a bit of silicon action.  It’s a bit less interesting, as there seems to be less variance to the circuit – or none?   Some differences in construction methods occurred, but that’s about it as far as I can tell.   Although I need to do a bit more … Read more

MOSRITE: Fuzzrite, Germanium Version

by
MOSRITE GE schematic 1de8551b080f

There are more than a few versions of the germanium Mosrite Fuzzrite out there – seems like they went through a few different construction technics and capacitor combinations along the way.  The details mostly seem to be lost to time (and rust). Here’s a bit of info that I’ve pulled together from various sources while … Read more

More two transistor fuzz mayhem – this is the later V2 silicon Mosrite Fuzzrite.  If you happen to have an excess of 470k resistors, this one’s for you. MOSRITE FUZZRITE – VERSION 2 – SILICON POINT TO POINT LAYOUT FUZZRITE – WORK IN PROGESS ON THE BENCH Using slightly different parts than on the layout … Read more
