Is whistling away like a good 'un.
I'm sure there must be a less noisy & more efficient way of designing inverters.
Though it does give 1350V, so it appears to be working.
Ish.
It's using a Generous Electric GM4 geiger tube.
Best before December 1959.
It was originally taking about an amp at 5V to give 1300V.
Then I changed the (10M input resistance) DVM for one of those old pointy needle AvoMeter thingies (20k/Volt on 3kV range: 60M resistance) whereupon the converter went click & sulked.
After faffing about for an hour or so changing stuff, it came back again & lo! now it takes 105mA at 5V to give 1300V.
Apparently it's a Royer converter. Coz it's got an extra inductor in the feed from the rail to the centre tap of the transformer.
And now it doesn't whistle so much either.
Damn.
Blasted thing just gave me a nice belt.
1000V stings a bit you know.
First one for ages.
It was switched off, but the capacitors were still charged up.
Oooo me finger.
Stone me, that stuff is hot.
Keeps yer dinner warm though.
