1.8a PS with runaway transformer

[mst3k]

I recently acquired a 1.8a power supply with a loose piece clunking around inside.
Turns out the smaller transformer had broken loose from its plastic base. I found a thread here:

...describing the same thing with the possible solution of a suitable substitute. Has anyone actually accomplished this transplant?  The Triad VPL36 700 is still readily available.
 
And yes, obviously, there are lots of other visible issues with this power supply...

I now think the VPL36-700 is way-overkill for this; I should have revised the suggestion after doing the brownout adjustment measurements which suggested the expected +5STBY load would be 100mA, not 500mA. I just measured the output from an original as 29VAC with a 100mA load.

A PC mount transformer that fits is, I think, a more suitable replacement, in spite of being only 6VA. (Unless you have a specific application where you need more +5STBY current, such as an X/Pi expansion card with a hungry Raspberry Pi that you want to keep running when the Lisa is shut down.)

I would try the "Signal Transformer" brand DST-4-28, or Triad brand FS28-200. I believe these have a footprint that matches the DataPower circuit board, and are rated for an output of 28VAC at 200mA. Currently in stock at the usual suspects.

As usual, thanks for the info.

I've ordered new caps and the transformer and will give this a go.  I've also been following the dialogue you've been having with @berskyboy RE his 1.8a PSU in anticipation that these two easy and cheap fixes I'm doing won't magically get this power supply working.

Thanks again!
