The last thing I worked on was re-flowing solder on the two 6FQ7 (blanker and color diff amps) and the 12BY7, this alone probably solved the video flashing/HV drop outs. After changing to mylar film caps, then re-tuning efficiency coil, cathode current was down to 185 mA from 210!
This appeared to be a regularly serviced TV (few original tubes and two replaced multi-section caps) but the solder connections under PW700 appeared not baked like they usually are. My other two CTC12 chassis plus a spare chassis appear to have been used much harder.
