SE/30 Sony Power Supply, Recapped



SE/30 Sony power supply after a full recap. Here's the cap list from DigiKey. It will not work for the Astec version. A couple of notes:

 

1. The "big guy" capacitor (620uF, 400V) is no longer made. The one in the list has a slightly higher capacitance at 680uF. The protection circuit (limiter) in the power supply can easily handle the negligible jump up to 680uF. Something very important, however: the legs on the replacement capacitor are not going to match the slits in the power supply board. I had to widen and lengthen the corners of the existing slits for the new capacitor to fit. I used a Dremel with a small abrasive bit to do this. I thought I'd taken a picture of the result, but apparently I was too excited to get the supply up and going and neglected to snap one!

 

 

So, this is a picture of the completed board, so you can see the size difference and position of the capacitors.

 

Very happy with this recap.
