You were absolutely spot on with that Sam thanks, one half of the box came away leaving fairly decent access to do some checks.
My reasons for wanting to get in there was I thought I had a noisy resistor as when it was switched to VHF there was a lot of scratching and rustling .
The trimmers were responsible for the scratching and rustling, after exercising them and a liberal dosing of servisol its now fine.
The other thing now is that I have a 100k grid leak resistor on the UCC85 that measures 130k, its buried at the back of the box with the tuner cord near it. I’m a bit concerned about getting in there to replace it, I have visions of catching the tuner cord with the soldering iron ETC so is it ok to leave it as it is for now?
