The power supply has a 1500 uF and a 1000 uF...and then, with the various branches, four 500 uF and a 200 uF. You can see the 1000 uF snap-in cap which I replaced this evening in the second picture...it is almost the same diameter as the original, but much shorter.
I had read that somewhere else about using larger electrolytics in the power supply, but I decided to leave it the way Avery & Co. designed it. The only change I made was to replace the 1 uF coupling electrolytics with metalized film, as I mentioned previously.
At least the new caps are smaller than the originals, making the unit look neater underneath.
