I'd like to increase the filter capacitance of a 21 year old subwoofer amp from the
current two 10,000uf 75v caps to a pair of 20,000uf 75v caps. The current rectifier is
a Fagor FB2502. Do you think this rectifier can handle the increase or should I
upgrade it? Also, for reference, the amp uses a single power chip per side as
opposed to discrete xistors if that matters. Thanks.

Why?

The extra capacitance could cause an increased current surge when the
unit is turned on but the power transformer will probably still limit
the peak current to a safe value. If you are trying to boost the
output power, you could overheat the power transformer at high sound
levels with the extra capacitance.
