I've apologised a couple of times about the length of this Thread.

I did start from the power supply end, checked the transformers and rewired everything around the on-off switch/ volume control and worked my way towards the aerial socket. All suspect capacitors have been replaced along with a number of out of tolerance resistors.Crumbling wiring replaced where required.

I'll go back again and re-measure V4 and V5 - checking everything as I go.

Part of my ongoing concern is that this set had been "got at" previously by the infamous "Phantom" who did many things I failed to understand - all now hopefully undone?
