Title: 1975 73 suitcase rhodes power amp issue not getting 24v
Post by: craig on March 11, 2019, 11:54:09 AM
Hi all. I'm working on a 73 suitcase that had been in storage for a while. I'm having an issue with the power amp. I get the 36v +/- (actually 40) but am only getting 15v instead of 24v. Would this be a 24v regulator issue? Diodes? It's been recapped (not by me) and stays powered fine, just not getting the right amount of v at that output. Thanks everyone!

Found it. Bad cap on the regulator board.

Dang, it!  I was just about to say...                    ...that I was stumped.

Two-dollar part, and the thing comes back to life! 

Great luck finding the fault quickly!
