Thanks Arran,

I see references elsewhere to engineering lower input voltage, e.g with a bucking transformer. Worth testing but it may not make all the difference that I think is necessary. The power transformer eventually becomes hot enough that I can't keep my hand on it. From memory, the radio draws around 1 Amp at a line voltage that may run around 125 Volts at times. The other thing I want to look at is whether the O/P stage or something else is drawing more current than it should from the HT. It will have to wait until I can visit the set again, as it is in our other place. With current "Stay at Home" restrictions, it might be a while.
