Default Osram Music Magnet 4

Just started work on my recent gift to myself. It's the deluxe model so has a quality oak cabinet and is complete and pretty good condition although the front panel has probably had a repaint. Valves are all there and it came with 3 'spares' although I expect these are the originals.

I have been looking out for one of these and wanted one with an original intervalve transformer but as only a minority still have them it is no surprise that both primary and secondary of this one are open circuit. First step was to extract the transformer from the painted copper case in preparation for a rewind which required the oven treatment to soften the bitumen - just hope I have the right gauge wire.

Seems to me that bitumen is probably not the best bedfellow for enamelled copper wire as it must give off some pretty corrosive chemicals.
