Default Re: Bush TV32.

Hi,continuing on from my last post,the last thing was replacing some of the wiring which had started to crumble.The loom from the rf deck and the one to the scan coils were ok.The one to the crt base was replaced plus the one from the mains in to the on/off switch.I have a auto transformer with taps at 100-150-200-240 used in conjunction with a isolating transformer,I use a small crt for test 100 volt first,then gradually increase to 150.At 150volt there was some signs of life,a blue spark from ey51 anode but no eht.I tacked in a silicon eht diode and we had eht and a raster.I knew the crt in this set was u/s but i had a tube from an old gec set which i thought was a 7201a but it turned out to be a 7203a straight gun triode which of course does not need a ion trap magnet.I fitted this and the only thing different was the focus magnet had to be raised slightly,also fitted a new ey51.
