Hi all,

I was just checking out a schematic for an AA864 Bassman at Schematic Heaven, and I noticed that the deep switch on the bass channel is wired to a .1 capacitor.

My question is, .1 picofarad, nanofarad, or microfarad? The schematic doesn't say. Sorry if this is a dumb question.

Thank you,


david

Thanks, Andy. :D

So, when reading a schematic, should I assume that all capacitors are microfarad unless otherwise noted?

I'm probably going to get my self in a jam here for trying to give a short ,in general,answer but to answer your question .No.
A micro fard is 1000 pico farads so there is quite a difference.
In Fender type amps the caps that are pico farads will usually be the ceramic and mica caps(250pf,500pf,47pf).The electrolytic (22@500,47@500)and coupling caps (.01@630,.022@400,.1@600)will be micro farads.

Thanks, TZO. I guess I have miles to go before I sleep when it comes to understanding this stuff.

Unless the schematic is English they like nanofarads watch out for an "n"
