    I need help, I bought this amp in 1992 from a pawn shop. I can't find anything on the web about it. Has the original 15s in it but they are completely toast. Should I just replace them? If so suggestions? or buy a new cabinet for the head?

    We could help you in selecting replacement speakers, but first you'd need to measure/post the inside dimensions of your cab. Plus let us know if your cab is a ported or sealed type, and if ported, give us some info and measurement's of its ports.

    It would also help us if you posted info about your amp regarding its power output specification's and minimum-ohm rating.

    I have the same amp... I cannot find anything on it. Cool Amp though. I had to change out the pots, capacitors and a resistor though.
    Could you let me know if you find any info on it? Also, How did you even get to the speakers? Is it a front load?
