My workshop inverter went bang last night, it's an old Glentronic gto type, lots of discrete components. As usual one of the thyristors has gone, taken at least 5 driver transistors with it. Luckily I have a spare thyristor, but if I cock up fixing the driver board it'll go bang as soon as I switch on....
No compressor, miller or lift until I fix it.
New one circa £850, and I'm on my last spares!

I have absolutely no idea what you're talking about!

I have a couple that also went wrong, I'll dig them out and see what make they are, if they are of any help to you give us a shout.

Maybe indeed, we'll see. Been out all day with our local rugby team, we lost, the first team won, so not bad really.
I have started stripping the control board, I'd rate my chances as 70% at best..

I'm up to 6 transistors, 6 jfets, 4 diodes, a few resistors and capacitors and pair of inverter chips. Once I've replaced all, I'll be testing the driver on a set of 12v bulbs, if it looks ok, then I'll connect the thyristor blocks.
The list sounds short, but I've removed and tested 18 transistors, 18 jfets, 18 diodes and loads of other stuff.
Maybe tomorrow night.
Trike build on stop....

bloody hell. ive lost track of how many of those drives ive thrown away!
although I'm sure if they were a tad more servicable and my own I'd have a closer look

Have you checked the flux capacitor?

Lol, you'd be surprised how close to the truth you are the manky. One of the failure modes of these is the dc link capacitors failing, I think I've changed two over the years.
Driver board now built up - testing soon.

"Soon" has taken longer than I thought. Tested the driver board tonight, it showed on phase not working - turned out to be a voltage regulator on the power supply board.
Now that's fixed, tested the high outputs, but need to solder some dropper resistors into the low outputs before testing them.
Getting closer.
The trike engine is out, welded the bracing bars, started prepping for paint.
