I sold them back in the 70s along with ADS speakers.

First of all, consider that power and perceived loudness is on a logarithmic scale. Doubling power only adds 3 db to the output level. I suspect what you really want is a 100 watt+ amp.

Replacing the caps might help because they are the first components to suffer from aging and yours are past the typical 30 year lifespan. As they dry up, they lose some capacity. I replaced the caps in my '81 Threshold amp for that very reason. If they really test fine, then simply adding more capacitance will usually not add any more power.

Depending upon the amp design, however, added capacitance can add more apparent bass slam and dynamics. Back in that day, I drove a pair of Magneplanar MG-IIs with an Audire power amp. I tripled the size of the power supply (via outboard box - Dyna 400 style) and upgraded the bridge. It was definitely a qualitative, if not quantitative improvement.
