With an even mix of curiosity and trepidation, I decided on a simple test of the 52-Set this evening.
I warmed up the Receiver and Sender Heater circuits for nine minutes, took a deep breath and switched on the Netting circuit for the Sender. This activates only the MG1A (300 Volt Dynamotor).
A constant sniffing of the air at the Sender Blower Door showed no sign of a smoke smell and a nice subtle ozone smell from the Supply Unit Blower was evident. After two minutes running, all was still well.
This at least tells me the problem is somewhere in the 1200 Volt circuits of the Sender.
Every little bit of information helps.
