"A am in admiration of anyone taking on a restoration of a TV in this old rusted and altered condition."
Hi Sam, It's truly a horrible rusty set and in fact if it hadn't such a rare and interesting model it would have been subject to the shop clearout. I'll do my best to tidy the thing up and make it more presentable. Most of those Maplin capacitors will be replaced with restuffed waxies. I've found some mid-fifties Dubilier capacitors which will look a lot better than those modern components. "It gets a mention in Trader sheet 1019."
Hi Colin,
thanks for the information. So in fact it's a proper white spot inverter rather than the more simpler peak white clipper.
The L63 valve is adjusted to conduct only on the white interference spots, the inverted spots are supplied to the grid of the CRT. Cancellation of the interference takes place in the CRT.
