PCM 70 Power supply recap

[timtom]

I‘m recapping a PCM 70. Is it better to increase some values of the Power supply caps as modern caps are way smaller?

Not really. The PCM70 is a very reliable piece of gear. There´s no need to second guess it´s designer´s circuits.

I don't see any problem if you increase a bit the values for the filtering caps, but more important than that is to use Panasonic caps rated at 105 degrees, then you know you used a quality brand capacitor and the higher temperature rating will make it more sturdy to increased temperatures inside chassis and last longer

I’d advise high-temp, long-life caps in the spec values with the highest voltage rating that will fit. I think that’s most likely to give a real longevity benefit, which seems more valuable than an outside chance at a nebulous or hypothetical performance benefit
