Rob is a braver ham than I. When my Tek 465 quit, I tried to fix it, but quickly chickened out.
Very nice that he painted his in Juliano Blue.
Dear Bill and Pete,
I do enjoy your podcast, and I must present an offering to the "Gods of Homebrew",
An on-line find of an old Tek 545 oscilloscope presented a chance to enjoy the warmth of 100+ tubes (once repaired)
The outside was heavily scratched, the inside looked like a chicken coup, but no major bits missing or broken.
Lots of cleaning, testing all tubes,(using the excellent uTracer tube tracer), replacing the broken 3, remounting the cooling fan, lots of reading about tube oscilloscopes, adjusting the trigger circuit, rebuilding 3 electrolytic power supply capacitors, sandblasting the cabinet and a coat of BLUE paint.
Voila, the joy of (visual) oscillation! (1MHz 2V p-p)
