Hi All..Newbie here..Great forum..
Have an Acoustic G60 - 112 amp left for dead so I grabbed it. Speaker blown out. Power supply OK with + & - 35 volts. LED's for Ch1 & Ch2 will lite when switched. Drivers and outputs checked OK with transistor tester. Connected 8 ohm speaker and fed audio generator to input. Nothing out. My cross reference book dated 1991 does not list any of the 4 IC's installed - 3 TL07ICP's & 1 LM380N-8. I assume they are some sort of op amp. Are they still available if needed? My book lists only some of the transistors on the board - some are JFET's. I want to start checking for signal path with scope but am in dire need for a schematic. Checked AcousticControl website and they only list tube amp schematics. Any one know what year this amp was made?
Thanks for any help ahead of time,
Dog
