They should be ok as I turned it off in a matter of seconds

No wonder the TV22 gave up! It did it in a state of protest because you took your glance away from it in favour of the circle!!!
Hi Lee,
Yes, I think it serves me right. Actually on balance the interludes were more interesting than the circle

DFWB.
Well David,
You hit the nail on the head. I do indeed have egg on my face now as it turned out that I had only replaced some of the capacitors in the RF deck. If I had restored the set for someone else, I would have replaced them all.
Mind you it suggests that the those TCC waxies are not all that bad. I restored this particular TV22 about 10 years ago and it has put in many hours of operation including a few hours without my attention at my Wedding reception.

Anyway. Photos...
The first picture shows the fairy light display.

The second shows the faulty C65, the lower 3nF capacitor in the picture.

The third picture shows a new capacitor wearing a waxie jacket. The new component being a little too big.

The fourth picture shows the re-stuffed cap back in place. I won't stop there though, but will replace more - maybe all the remaining waxies before I power the set up again.

Cheers
Andy
