been wrong before. I have a working 204C and schematic but the ps is
just enough different that I can't use it for repairs. Something should
show up sooner or later.


What do you need? There are only a couple possible power supply
configurations. If you draw out that section of the circuit, and
what the output voltage is, I'll tell you what the values ought to be.
