No, David, but after checking I see that my Little Maestro has a UCH81 and a UCH83, though I'm sure the latter is fine. Obviously the filaments are OK and I can megger the UBF89 for H-K shorts.
My money is still on a dodgy connection somewhere, or possibly one of those resistor-like capacitors has failed without going bang.
I've been otherwise distracted for the last few days so hopefully I'll be able to concentrate on it better soon.
It's certainly grown on me stylistically and before it went off was sounding very nice through the Roberts speaker. The charms of PCBs still elude me though.
