I'd crank up the variac a bit till I got close to 10v on the filament string (at the 200mfd cap). I trust the audio stages are working ok? If so then try injecting a 455kc signal though a small cap (200mmfd-.01mfd not critical) at pin 2 of the 1LN5 if ok then pin 6 if ok when pin 2 of the 1LC6 then pin 6. With the generator on pin 6 you can align the IF transformers.

Do your self a favor and only use the digital meter for ohms measures.Get a VOM or if you are going to be measuring hi impedance circuits a VTVM. Digital meters can't deal well with any sort of voltage with signal on them.I think what happens is some of the semiconductors act as diodes and rectify the signal portion of the voltage and it comes up with a goofy reading. There ok if it's just voltage  like right out of the power supply or cathode and screen grid circuit but plate and control grid circuits I don't trust them. Once I was working on the TV set, measured some voltages and they where no where near what they should be. Was thinking this set is all kinda screwed up. The next few days I was scratching my head tiring to unlock this puzzle. Left my Beckman 310 meter somewhere so I grab the Simpson 610 ('50s analog meter)and the reading were much closer to what they should be.
