I wouldn't normally bother posting about this as there's very little to say but given that it's acquisition was discussed I thought I may as well complete the story.
It was playing when I arrived to collect it and I was pleased that the grid-coupler wasn't a waxie or a Hunt's.
The controls needed cleaning and beyond that I only had to change the output cathode bypass cap - one of those red and black Pleasey jobs that may as well not have been there, the tone corrector, mains filter and C22 as all the others were discs. The anode resistors on both V1 and V3 looked a bit cooked and had indeed risen from 27kΩ to about 35kΩ. Somebody had already replaced C27.
One of the knob-brights is missing so I've taken the other two off and will make three matching ones when I get some suitable brass. I'll give the original one off the tuning knob to Alan.
