Improving old TV sets.

[Geordie McBoyne]

Today, that horrible mains dropper was replaced                                                                                                                             A piece of 5mm threaded rod is employed to position new component correctly.   During the course of re-soldering the wires from the voltage selector panel a wiring mistake was found.  It was found that the heaters voltage adjustment panel  had a wiring mistake, the 220volt tap on the mains dropper had been connected to the 240 volt tag on the voltage adjustment panel.   See first attachment.  All this means that the valve heaters have been overrun since the set was made.  And this hasn't done the CRT any favours either, it's even dimmer now.  The N308/30P4 line output valve needed replacement, a GDR made PL36/25E5 works fine as a replacement.
