Well I had a trip out today, 355 mile round trip on some Ebay collections, I am absolutely knackered found the weather grim this afternoon. Basically saving a Murphy TV chassis and some old radar tubes to see if I could use or play with.
Back to the project, I have built a tripler to add to the mains transformer, it outputs around 1KV, just awaiting some potentiometers to arrive for the focus and brightness control, need to source a small 6.3 Volt transformer for the CRT heater separate from the rest as that will be up at around 120 to 140 Volts
I did find one white screen tube, but I doubt I would be able to use it with such a low EHT.
