Starting to work on my Philco 89 and I just removed the pwr trans.  There is a LOT of wax under the trans so I'm guessing it got pretty hot at some point.  I hooked it up to my variac and surprisingly no smoke and all the voltages are within spec.  Plus resistance measurements from the frame to all of the windings reads infinite.  My question is whether all the wax loss will affect the insulation resistance or cause some other problems down the road.
