Suitcase TV Fun

At first glance, both appeared to be relatively untouched. I really see no signs of repair on the Sentinal chassis.



The Airline chassis has had the two electrolytic caps behind the terminal strip replaced with a two section cap.



However, its IF stages have also been modified to allow the use of 6CB6s rather than 6AG5s, perhaps for higher gain. There is a tag taped inside the set for a service company in Corvallis Oregon, which was a fringe reception area for Portland and Eugene stations. Hope it was aligned after the mods....

Not so original here... both have had a bit of repair work. Here is the Airline:





And the Sentinal:



Looks like some good fun ahead sorting out the repairs and modifications made on these sets.

Bypassed the voltage doubler input caps to get some B+ and checked out both sweep chassis. Both jugs seem to make light, and both sweeps appear to be running on the Airline sweep chassis, while only the horizontal sweep is running on the Sentinal.

Airline:



Sentinal:



All voltages are low, HV on either set is in the 2.5 to 2.8 KV range. Some audio was heard from the Sentinal rf/if/audio chassis.

Both sets show promise.
