Looks like a later version of mine:

And I had a copy of this TV when I was a teenager, as well. Used to be my father's mother's TV she had in her apartment in NYC, back in the 50's. We inherited it when she checked out in 1960, and my father tossed it in the mid 70's. Got another one off the bay a few years ago. The door on hers fell off, and never had it for the one I have now.
Replacing all the wax caps should be all you'll need to do. Assuming the circuits in yours and mine are similar, be sure to use a temperature stable cap in the horiz oscillator, the 0.01 cap, parallel with a 22K resistor, mounted across the horiz phase coil, between the 6SN7 and the 6BQ6 Horiz output. Actually, as it has a 22K resistor in parallel, you probably could get away with just leaving it in (the 22K resistor should swamp any cap leakages). I first used a ceramic cap in my TV there, but the horiz hold was too drifty. Then used a orange drop type, and that fixed that.
