If so will that melt the glue holding that transformer together? better try it outside as it'll make dreadful fumes if it does work. Or is the glue inside between the former and the core where you can't get at it? RR.

Might be worth checking supplies....maybe a duff decoupler on the I.C supply rail.Doz wrote:Does the TAA700 do anything in the way of beam-limiting? I wonder if this is why I have precious little video.
I doubt it. I think only colour sets used beam limiting.....never came across it on mono sets.
Blanking or gating seems more likely.
