Sol-20 power supply capacitor failure

The reason the Sol I’ve been using is unreliable (mostly in the first 30 seconds after powerup, but sometimes later also) is that C8, a 18000 uF 10V electrolytic filter capacitor for the 5V power supply, has gone high-leakage.

It’s easy to find an electrical replacement, but difficult to find one that is the same physical size as the original.  There has been so much advancement in capacitor technology since 1976 that the modern ones are less than a third the volume.
