PG M50 power supply problem
Posted: Tue Jan 20, 2009 11:57 am
Hi all i have a PG M50 with a blown power-supply cap (4700uf 35v) and when i am about to replace that one i measured the voltage and its +37v on positive and -30v on the other one ....i have ~25v on the input on the supply-diods but i have to much voltage on the positive side on the output.
The amp runs and sounds ok but it gets hot!!!
There are some components behind the 2 power-diods (under heatsink)4 caps 10nf and 4 10ohms resistors that are a little burned..!! could they have something to do with my problem.....looks like some kind of filter array or??
Hope someone can give some advice
cheers
