I was thinking that the transformer had shorted turns or something causing it to overheat. Today I was looking for a replacement mains transformer and wanted to measure the HT AC voltage to get something equivalent. During the measurement I noticed an unusual amout of heat coming from near one of the panel lights. It turns out that the insulation is breaking down in the bulbholder between the 6.3 VAC and chassis. I've pulled the lampholder away from the chassis and now everything is ok, the mains transformer just gets a bit warm and not hot any more. Photo is the faulty part, I may be able to rebuild it
The full system now working with the Parmeko KT66 amp and Lowther Acousta PM6 in my new office after house move.
It had been running for an hour now and the transformer is very warm, it may be faulty.
The amp transformer is just warm.
Is it usual for transformers to run hot?
