Default Crest Audio 4801 PSU Capacitors

Hi,
I was wondering if anyone knew where to source the 17,000uf 55v capacitors that appear on the power supply pcb.

I have searched, but cannot find the ones in the correct package size, they all seem to be 2.5" diameter.

Many thanks

Diane

show us the type (mounting) and size of the given capacitors. If anything, go for slightly more capacitance, not less...as most commercial designs are a hair skimpy with energy storage.

All sizes are standardized if they are snap mount or 2.5" diameter screw in type. If it is an amplifier that is more than about 10 years old, nowadays..there is likely to be a better quality and slightly bigger cap for that given can size.

They are 1.5"dia, 3 pin snap in and approx 3" high.
I'm a little nervous at changing the values as there are 4 caps all linked in parallel, I could change them all if I was changing values, bur realistically it's going to cost in excess of 60 to do that, so I would rather source one that could just be swapped in.
