What's the model number of this Bush TV set (TV350)

clear away that inch-deep layer of dust and crud, then try again!! EHT doesn't like that stuff, you know...!

It's actually the EHT rectifier part that has failed, on the top of the transformer. We tried the set, and a picture did appear, but suddenly vanished after a short while. Paul did indeed say he thought he could smell something burning - he has a better sense of smell than me - and indeed when we looked, a spot on the top of the rectifier was "bubbling". It's an encapsulated unit, "hard wired" to the overwind on the LOPT itself but as Kevin had done in a post above, this can no doubt be replaced with a suitable EHT diode...

Perhaps the original unit is using the "infamous" selenium discs, it's certainly big enough, but there was no "bad" smell associated with one of these units dying.
