I totally agree. Buying a new power supply is wasteful as long as it
just failed due to some capacitors. Like in the three Transporters I had
here for repair. It's a shame to toss a module that has two or three
failed out of more than 20 components, and spare parts are really cheap,
even the good ones. No need to put audio quality caps here, eventually
this is just about the display power source.
But the quality of the capacitors is just half the story. The other is
(imho) that they should be further away from the heat sources on the
PCB. That's why I mount new capacitors with the full length of their
legs (isolated of course) and glue them down to the Transporter's bottom
shell. Even crappy quality capacitors will live much longer this way.
However, not everybody has the tools and skills and courage to do this.
If doing the soldering is too hard, and nobody is available to do it,
but tools are at least sufficient to replace the PCB with a new one,
that's an excuse.

I am thinking of selling a few modified PSU boards, brand new but
equipped with quality capacitors (Panasonic or similar) right from the
start. PN me if you are interested.:)

PN me if your Boom / Classic / Transporter display has issues!
