Anyone know anything about these amps? I am looking for a schematic.

There used to be a great Acoustic website, but it seems to be gone now.

The 150B is the bass version of the 150 amp, I think 75 watts into 4 ohms. Transformer driven output stage. There were two versions, the earlier had light blue front panels and large aluminum knobs, the later version had a black front panel with smaller black plastic knobs.

I may have a copy of the guitar version schematic somewhere. I'll look tonight.

tboy: thanks for the update, I thought it was gone for good.

e.c.:I have posted the pre-amp and power amp schematics on the ampix site.

Thanks. This amp is the earlier one with light blue fronts. The schematic helps but does leave out some part numbers. Someone really had "fun" with this amp.
