Hello,

I am looking for a schematic for an early 90's Randall RB100 bass combo amplifier. This is the older version of the RB100, NOT the newer version with equalizer sliders.

Thanks!

IF it is the real early version such as used by Ike and Tina Turner, not the later Pantera era, back in the day "everybody copied the Twin Reverb idea" so Guitar and Bass preamps were the same (clean, no distortion), only the Guitar one added Reverb and Tremolo.

So if you find the old Guitar one, it will help you.

I have them somewhere, in some old hard disk, haven“t seen them for many years.

I ended up purchasing a PDF schematic from MusicParts.com.

I've not bought anything from musicparts.com, but depending on their EULA you wouldn't want to do that.  While I do enjoy all the schematics, I want to try to make sure things posted here are legal.
