For years I've been using #34 wire and never had a problem in any Philco. I've also found that the number of turns isn't super critical in the plate circuits and one or two turns more or less won't matter. A perfectly wound coil looks professional but if turns overlap that's OK too. The most critical thing in the coil winding is the phase (direction of winding); if it's wound backwards it's not a problem either- just reverse the leads of the coil where they solder.
A bit of sticky beeswax melted on the surface that the coil will be wound upon helps greatly. When finished winding, a pinch of beeswax melted into the coil with a soldering iron will hold it all in place nicely.
