content: Looks like mostly ancient junk - surprised you bothered taking as much as you did ( do you have an easy way to dispose of stuff?).I too can't resist a dumpster but have got a bit more selective in my old age...

content: I was watching the teardown of the power supply at the end and I'm surprised that there was no attempt to find out if it still worked or not. Oh well it might make the subject of a repair video. I'd certainly be interested in seeing if the dodgy earthing has shorted out the transformer.

content: Quote from: aqarwaen on October 16, 2018, 11:28:17 pmYes, forgot about that. In some countries it can be hard to dump anything regarded as commercial waste without paying. I generally go to the local council "dump" at lunchtime when nobody is around to notice the carcasses of wierd ex-teardown items.

content: That 0-500V Power supply is just my sort of project style, and something I legit need.I don't mind fixing the odd missing wiring around the transformer, or even rewinding it.No schematic, but I'll make one to go with it.Will have to see if I can horse trade with Dave.

content: QuoteIt most likely is and the vacuum diode may have been long dead as they did not have large lifespan. However substitutes or NOS parts still can be found.
