Well success, replaced the diode and filter capacitors. Set warmed up with no problems, still no raster, although I can hear the flyback's distinctive whine.
Found that the 1X2B was faulty and replaced it with a working tube.(thought I had tested all of these
) Alas, still no raster. Checked the damper tube along with surrounding connections, and main voltages appear within 1-2 volts.
Finally pulled out my capacitor checker and tested the single 4kv 160pF ceramic capacitor in the flyback circuit just to find that it had failed. Well, time to order parts, it's always one thing or another
Anyone know where I can purchase caps like this?
Cheers,
