Try to tweak the coils w/o any equipment or knowledge and hope to eyeball it to get best picture ( prob no the best idea, but an option )

Try to get a Heathkit IG-57 from ebay some time, which will have no probes, ( can be made ) and no attenuator ( can be got separately ) , which will be in an unknown working state, but can be calibrated / tested via the manual, in order to do an alignment procedure that is tricky and not fully understood :/
Example, SAMS says to disable oscillator section of the mixer-osc, but gives no info on how to do it.
Taking a wild guess, I would say removing one of the bias voltages to the tuner, but I'm not sure.

Or lastly, hope to set aside enough $ some day to haul it 20 miles to a place that can hopefully do it, & get it there & back w/o damage :/

sigh...

Ways to disable osc stick the tuner between channels (all turret tuners and some water types will open the osc coil circuit between channels, take a spare osc tube you don't like and clip a grid or plate pin off and stick that tube in.
