Well its starting to really come together now  $#$ so i thought it was time for another update.

1st couple of pics of the power supply having been rebuilt, using new bridge rectifiers with heatsinks added, all pin headers replaced and new 1N4007 diodes for the display high voltage. Also i am replacing connector housings where needed, if they were burnt looking, and the freshly de-rusted and repainted transformer shield.

And a pic of the solenoid driver board installed, with new filter cap for the 5 volts and all grounding upgrades etc done as per Clay's repair guides. Notice someone has replaced the two small transistors in the high voltage regulator circuit, using TO220 cased transistors with pieces of aluminium angle mounted to them for heat dissipation on place of the original 2n3440 transistors. I may change these back to original later on if i can find the small heatsinks that fit the original transistors somewhere..
