paul_5 Posted May 21, 2013 Share Posted May 21, 2013 So anyway, I ended up replacing two zener diodes (1N4737) on the power supply and the 'limiter' pot yesterday and now I have an oscillating machine but no bass amp. Anyone got a service manual (or similar) for this? Quote Link to comment Share on other sites More sharing options...
paul_5 Posted May 22, 2013 Author Share Posted May 22, 2013 Well that was an easy fix - replaced the first 2 opamps on the board (they're even socketed) and it's business as usual! Quote Link to comment Share on other sites More sharing options...
BassBod Posted May 22, 2013 Share Posted May 22, 2013 Good to know...mine's been a little wonder, but its over 20 years old now. Only a matter of time before something goes. Quote Link to comment Share on other sites More sharing options...
