I am in need of a schematic for an older RadioShack graphic equalizer. Any
help greatly appreciated.

It's often possible to fix an equalizer without a schematic. What's it doing
wrong?

Radio Shack used to be pretty good about supplying schematics on
request.

I have a 31-2018 ten-band eq. Don't know how similar it might be.

The graphic spectrum graph leds were all on all the time.

It's now fixed! Problem was an open series pass transistor in the negative
power supply.

Schematic would haved saved some time, but no biggy.
