1035 may be the same as 935 - I know 920, 1020, 1120, and 1220 are pretty much the same... The 1135 is NOT the same as 1035 - it has the current FM band as well as the old one... I do have the Sams folder for that one...
The eye tube acts as a tuning meter - is probably weak - but replacements are available. FIRST, the caps are probably leaky, can take out a transformer and/or tube. And there's a lot of them.
