I'm at a loss.
The deflection board has been rebuilt with new caps, all new transistors and voltage regulators, upgraded diodes and no modifications.
The bottle caps are substituted with 15003G and 15004G which are compatible upgrades.
The U07s and U57s are now ZTC653s and ZTX753s, again, confirmed compatible upgrades.
Question is, where does this board get its power from - is it from the game board or the HV board? The problem is that the spot killer remains off for about 5 seconds and then comes on followed by a smoked R35. Post-apocalypse diagnosis has resulted in the aforementioned parts all shorted out.
I'm thinking that perhaps the power going to the board could be the issue, but I'm nearing the end of my bandwidth on this one.
