Try changing 36 cathode resistor to 8.2K.
Lacquer will not harm the coil (I've rewound literally hundreds of Philco coils using lacquer or clear nail polish over the new winding - never a problem yet, knocking wood).
Use a mica 680 or 700 pF cap for the 36 cathode.
You may have to try different 36 tubes until you find one that oscillates normally. This was a known fault with the autodyne circuit.

Those green spots on the coil will eventually corrode and fail. You know what to do (unfortunately). This takes either 30, 31 or 32 gauge wire. I have used 32 with no problems. Although...I don't think this is your (current) problem. This will become a future problem, though.
