Signal issue on a Motorola 7VT2?

[zeno]

180 V on V2 plate means its not turned on so either
dead osc or mixer stage. Clean the crap out of the
switches first. Then tubes. Look for bad socket or
broken pin internally. Rocking the tube will show it
sometimes.
If V1 stage dead but everything after OK will display
snow & a strong signal make it through anyways but
will be snowy.
