Re-capped the Airline sweep/display chassis and both rf/if/audio/video chassis, and replaced a few resistors that were way out of tolerance, and now have 2 complete suitcase TVs that make a picture and sound, although more work is needed on each.
The Airline exhibits some horizontal instability and some flagging, I am digging for some better 6SL7s for the sync circuit. The new 6Y6 did bring up the HV to almost 5 kv, which I guess is close enough to spec.
The Sentinal HV is only about 4.2 kv, so another 6Y6 has been ordered. Arcing also occurs periodically, so I will have to fix that before it gets its new 6Y6.
getting close,
