Thanks all. Now sitting listening to it! A nice easy one. Usual wax cap replacement, and, unusually( for these) HT can was u/s. Anyway a couple of 47mF @ 450 volts cobbled in, a dodgy valve holder on the UF41 causing intermittent open circuit heater chain, and a silly wiring error by your truly. Anode resistor for the audio triode had drifted high as well so treated it to a metal film 1% which was all I had.
Not finished( they rarely are) but it’s the best I could do with the limited box of bits I brought in with me. HT caps will be tidied up and more work to do on the dropper. The grey ones always seem to go, unlike the green ones fitted to later models.
Ha ha, yes a Covid pre op TEST. Blooming spool chucker.

Yes I like “ Trouble in store”, but my favourite is “ The early Bird”( there’s a nice radio in that one too. A Ferguson I think). I am fond of “ The road menders” too.
