I am wondering just how youy make a PCB where you
can't replace the
flyback transformer....
With glue perhaps? What I should have said was that in one revision
the flyback was connected with a plug and a designated FRU (Field
Replacable Unit) by digital and in the other case the whole circuit
board with a soldered on flyback was an FRU, not the flyback itself.

Suddenly I'm reminded of the horrid stock Commodore power bricks
where the whole brick is epoxy. I went to a lot of effort to dig up
a good 3rd party brick for my C-64 that can be easily worked on.

Odd, the C128 and A500 bricks are easily opened an serviced. I seem to
recall that the C64 brick broke easily, perhaps Commodore got a lot of
complaints from service shops.
As a side note, you can replace (or splice in) the C128 square power
connector with a C64 round connector on a C128 power supply to allow you
to use a SuperCPU, RAM expansion, etc..
