At the moment, I am not too bothered about it, because with 150 Volts HT, it is OK. I am concentrating more on replacing the wiring and searching for more faulty components, after which the instability may clear up of its own accord. I can't imagine that all the EF39s that I have tried have lost their metailising connections, although I haven't actually checked them with the meter. Currently taking a rest from it.
