First look inside the Heathkit OL-1 scope. I removed all the tubes and the CRT. The rear support bracket for the CRT is missing. And it definitely is not the original CRT. Going the vacuum the interior and inventory all the tubular caps plus the B+ can.
But before ordering any parts need to determine the condition of the power transformer. That's the only part that's unobtanium and if it's no good the entire restore is senseless. Luckily quick DC continuity check shows it's OK. Those two .1uf/1200V HV caps are physically sticky to touch.
Here's the vacuum tube complement.
1V2 HV Rectifier
6X4 B+ Rectifier
12AX7 Twin Triode preamp
4 – 12AU7 Twin Triodes for the Vertical and Horizontal amps
3EP1 CRT which was real tight in the front bezel. That green grid is not original.
All the tubes are readily available on Ebay.
Front panel. Going to completely strip it down and clean it. That's not rust. It's dirt. The case is going to be cleaned and then spray painted. Undecided on color right now. So, that's it for now. Will provide updates as progress is made.
