Title: Any ideas?
Post by: curtis on December 27, 2014, 03:43:10 PM

I think most of y'all know the problem I'm having with my 3000.

I found this auction on ebay and was wondering what might be the problem with it.

I'm thinking some filter capacitors might be the problem.  If so, that would probably be a fairly easy repair.

Comments?

That would be my first guess. Probably a lot of ripple on one (or more) of the lines.

Ripple.  Hmm.  From what I remember looking at the ps board (not home right now), that power supply isn't exactly the easiest thing to work on, but I've seen worse!

Might consider it.

ATX adapter  + ATX, ITX or Pico PSU would be a better long term fix.

I'm with Lurch on this one, I would go witha TFX PSU tho.

The Amiga 3000 PSU is 110x63x175mm (WxHxL) and the TFX standard is 100×63.5×125 mm (W×H×D) so they are pretty close in size (lenght don't matter).

be quiet! makes some quality PSU's that will last for a long time with really low ripple and as a bonus they are quite quiet also :) At loads the Amiga 3000 pulls i'd bet the "be quiet!" PSU's will be well under 20dB

Just got home from a Christmas trip and the amigakit adapter came in while I was gone so after I get settled (and rested!) will start working on that project again.
