I've done a bit as it's a total pig to work on.
I changed C61 (Ekco schematic) which is THAT one, C68 and C57. The latter is something to do with the tuning inicator. This still isn't working but the heater is glowing.
I've had it playing my DAB for a couple of hours now with no problems. I don't know if C68 was leaking and pulling the HT down or what. On LW and MW it's fine but I have noticed on strong signals as well as the station it brings in a hum which isn't there between stations or on weaker ones - it's 'silent' on Gram.
The biggest issue is still VHF not working. The obvious thing is the band switch but that seems pretty good with no excess crackle when it's operated. I'm going to treat myself to some proper switch cleaner so will give it a blast with that when I do. For the last twenty-odd years I've used WD40 with no problems but now I'm working on decent equipment it deserves the proper stuff.
Lack of VHF isn't too great a problem as I can plug my DAB or phone into it but, obviously, it would be nice if it did work. I'm loath to start any mass re-capping exercises but if anybody can suggest specific ones to change I'm quite game. Failing that it's usable like it is and sounds great, though it's playing through my bench speaker so may be different on its own, so I would mind leaving it 'til I've got a better idea of what I'm doing.
Thanks for the help so far.
