SE/30 PSU Voltages

[erichelgeson]

Hi!

I'm trying salvage what I can from a maxwell bomb SE/30 and recapped it's analog board so far and was going to test it. Before I test the analog board I wanted to make sure the power from the PSU was correct. It's an Astec PSU. I took some readings and they were not "stable" mostly going up and up as it got warmer and "odd" numbers (not 12,5,etc).

If someone has the pin voltages at the PSU output connector I'd appreciate it! My google searches came up empty.

Thanks,

Quick edit - I think this diagram R, Y, O, G (colors) is what I'm looking for



Edit:

Color, Expected, actual, after 5 min

Red +12, +6, +12.75

Yellow +12, +7, +13

Orange +5, +0.5, +6.27

Green -12, -14.7, -8.83

I don't think I should hook this up to anything Would recapping even be an option or is this a goner?

I took a known good PSU from an SE and put the recapped analog board on that, tested the voltages, all was good and booted right up (well brightness was all the way down, so that took a few minutes of debugging )

Question still remains, what should I do with this Astec PSU.

It's probably worth the $9 or whatever a new set of caps would cost on the Astec. I just redid one and it was not so hard; the heatsink assembly on the end opposite mains entry has to come off to easily access all the caps but that was only three 3-pin devices and a couple of ground lugs to desolder. It's not the Sony which people seem to like more but one day you might count yourself very lucky to have a spare in a drawer. In terms of soldering power supplies are as easy as it gets - big lead holes, easy to clear with wick.
