I'd pull the 7Y4. Turn it on. Does the pilot lamp light? Is it's brightness correct, not dim? Check rubber filament wiring for shorts. If you leave it on for 5 or 10min does the transformer smoke or get hot to the touch? Has the transformer lost wax out of the bottom and smell burnt. Measure the HV and filament winding for proper voltage without the voltage fluctuation.
If it has any of these issues I'd look for a new one.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
