I've got here a 1971 Fender Blender. Sounds rad.
So, I'm poking around in here and have found a few things differing from the original Fender schematic http://www.freeinfosociety.com/media/images/4068.jpg
As opposed to 5 2N3391, I'm seeing 2X 2N3565 and 3X marked 121-433 7111, the manufacturer's logo is tough to make out, maybe Nat Semi?
Any of y'all know anything of these 121-433 trannies? I assume "7111" is a date code.
And the diodes... as opposed to glass bodied 1N276 GE's, I've got these white, solid bodied little jammies marked only "920". 1N920???
