Question now is whether to tell the Radiomuseum or not? Am I definitely correct in my deduction?
It's a Howard Craven upload and he is seldom wrong, don't want to upset anyone - again.

Had a couple of hours today restuffing another four 0.1uf paper caps, melting out the tar ends is messy but they look original when done.

Discovered that the output coupling transformer is open circuit on all windings so it's an unwind and count the turns job. The core is "E" lams laid alternately without "I"s and show green corrosion so it's probably the dreaded green spot corrosion that has caused its demise.
The wire is 0.08mm diameter including the enamel insulation, what size will it be?
