Old-school cap notation/Gibson schematic
« on: November 09, 2023, 03:36:48 pm »
Looking over a Gibson schematic , one a few that could potentially match an amp my son has.

A few coupling cap values are listed with a double-micro notation (500uuF).

Does that convert to 500pF?

Yes. Fender wrote MM (micro micro farad) on some schematics, meaning pF.

Back in the day we called them Micky-Mike rather than micro-micro.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
