Acoustic Control Model 140 Schematic Needed, Please

[hackworth]

Hello Fellow Bass Players and Classic Amplifier Afficionados,

I saw that a gentleman here offers the schematic for the Acoustic 140. I need to repair one I recently purchased. If you could please point me to the schematic and some parts suppliers, it would be greatly appreciated.

It is good to keep our fine old amplifiers out of the trash bin and alive and functioning properly. In many cases, they're better than what can be bought today new.

I am making a LH bass guitar from a Str*t copy body for 8yo son. The acoustic, when I get it running will be part of his bass rig.

Many Thanks. Anyone have any sources for replacement transistors and power transformers?

Mouser, Digikey, Jameco would be good for transistors.
For transformers you'd need to find another unit to raid one from since the old Acoustic Control Corp is long gone. If you're lucky, you MIGHT be able to find out who's making the new amps and see if they bought up the remaining parts from the old Acoustic Control Corp....

Thanks for that. If I'm really lucky the PT will be OK. They're simple enough to bench test. I thought I'd seen somewhere on the web that there are drop in aftermarket transformers available for the acoustic 140. Can't find now that which I thought I'd seen.
