Good idea Jerry I have a multimeter but the eyesight may be a struggle!

If the worst comes to the worst, I may still have a good tuning gang from a scrapped set. Should be easy enough to clear any shorting plates though.

Well I think I have rectified the fault with the tuning capacitor. I tried looking with a bright lamp and a magnifying glass but could not see any obvious points of contact. I took a thin piece of card and slotted it between the vanes one by one again with no success. I was about to give up (very cold in the shed at 10.30pm), When I noticed th tiniest spot of something? Resting between the end of two of the vanes. I removed it with some very fine tweezers and hey presto the radio functioned correctly. I’m not sure what the object was as it was too small to examine even with the magnifying glass. In order to acces the tuning capacitor the bracket that holds the ferrite rod aerial has to be removed and unfortunately I broke one of the connecting wires. But it was simple to solder back in place. The radio now functions well.
Thanks again for the help
Lynton

Do you have any other parts left over from the scrapped set? The two wire tubes that guide the tuning cord for the FM section are damaged on my radio. I have effected a temporary repair and been on the lookout for some small plastic tube to replace them with as I assume that direct replacements are no longer available?

Looked at this but the wires are soldered at the bottom of the capacitor and covered with thick insulation. I think I would have to completely remove the capacitor to get access?

No need to do this if you have cleared the fault.
