    I've acquired a Polytone mini S15B bass amp, it has two jacks next to the speaker Jack marked biamp, bass & treble.

    Are these line out jacks? Or are these speaker connections? I can't find a schematic, some polytone amps have multiple speakers but not this little guy, so a line out makes more sense.

    Anyone know for sure?

    It's for connection to one of the two speaker Polytone ext cabs, the 1x10-1x15 is a good example. The treble connection would drive the 10, the bass the 15. They are not rare but not common.

    Thank you. I was hoping for a line out, but I was skeptical. Glad I asked.
