Not a time to re engineer ! I went to my Sams but to my horror the folder is missing the Admiral ! It only has a Panasonic & two copies of a Sylvania B&W.
So post the power supply part of the schematic. Its either on the bottom left or on a separate page as a rule. Check the main B+ it should be in the range of 120 - 130 V as a rule. It should stay constant running at the 100-140 VAC
input. ( see schematic ).

It would be nice to get this set saved. Its one of the last Admiral engineered
TV sets & very well built. IIRC they folded up in 1979

I don't have any of usable value or wattage at the moment, but in looking for one, is it a huge problem if the line voltage drops below a certain point?
