Capacitor interchangeabilty

by toomer3027 » Sat Jun 07, 2014 2:30 am

Hello all.
I have a Rock-ola 488 with a faulty capacitor on the rectifier board in the power supply.
The capacitor is 1200MDF 50VDC. I haven't been able to find an exact replacement and I was wondering what cap would interchange on the board that would work and be readily available. Thanks in advance.

And you most likely won't find an "exact" replacement.
Us techs usually go for the next higher value anyway.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.

1200x63 are available, also 1500x50--not critical in a rectifier circuit--just don't use lower values--
