Thank you both for your advice I’ve had the amp apart and after a critical look and remembering g what a pain it was soldering all those pin connections I’ve decided that discretion is the better part……..until the hum gets worse.
So it’s a change of valves for now, having just broken one.

I’ll try those Amprex, Boondi as you say only a couple of quid extra

Bob, yes always amusing looking at Hifi collective, deep pockets a must.

Thanks again for the advice I think a “conservative” upgrade when it becomes unavoidable
