0:32 Wow! I'm really impressed that someone took the initiative and devoted his time and resources to rescue all this equipment. If this sort of thing would happen more often, or -- more precisely -- if universities themselves actually encouraged this sort of thing becoming the normal thing to do rather than the exception! They don't even have to have staff deal with it, just allow student groups or clubs to take care of things the uni does not need, with the right of first pick going to the club members of course. In unis, space is at a premium and staff do not have spare time so the regular thing is for old, unneeded equipment to end up in the skip as fast as possible. This guy here is the exception and is showing the way by taking advantage of the power of social media. The trouble is, not all unis have the space to keep the equipment until it is sold off/taken away.
They are cool power supplies, my mates got one of similar age still working with all original caps etc, I've got the high voltage board from a similar supply, it's a self oscillating push pull with TO3 transistors, probably Germanium, il send you a picture if I ever stumble across it in my horde 😅..
Hah, i have this exact supply, but then in the 15kV version. World quite well, and seems fairly low noise. Edit: the external jack in mine is not in fact a remote trigger, but a jack meant to add a current meter in series with the high voltage output (on the low / ground referenced) side obviously). Yours seems to have the same functionality. Look at the label next to the plug, it includes an A for amps.
As an addendum to my earlier comment, here you can see me using mine to provide bias supply to a small cloud chamber i made as a covid lockdown diversion. Notice the ammeter on the top of the instrument. this is plugged into the jack in the back, providing accurate readout of output current. I put a little switchable divider in there to be able to read 0-100uA range as well as full scale output of the supply. ua-cam.com/video/IUssuAcfkQM/v-deo.htmlsi=odM2YCtDFegktCyb&t=28 This setup has proven quite useful for carefully measuring things like leakage and breakdown voltage of common parts such as reed relays, or isolation values of various components. I think partly because the output is fairly well behaved.
I managed to find a manual this morning, which I didn't earlier. I got a schematics of it now and I can see you are right, it is a current meter. I assumed too much from the non-high-voltage jack, so it must be connected near ground voltages.
8 kilograms of copper mesh. wow, and a bad powersupply. perhaps you should do a troubleshooting video on that, i get my delivery friday the november 10th, when i get my flatcable spreader from a substation in jutland. and perhaps i also continue with my slayer exciter.
@@KaizerPowerElectronicsDk you need it to be a proper regulated adjustable power supply? I wish I knew, I took one apart, it had 10 big flyback style transformers in parallel and a resonant Full-bridge driver 1A 12 kv output... 🤦🏻♂️

46 years old but looks almost brand new!
It was taken good care of! No dust was a surprise :)
looks great for something made in 1977 :3
It was clearly taken care of in a pretty clean lab, no dust inside :)
That's cool Mads but if I buy anything else without selling some stuff first il end up divorced 😅
It was a rescue mission!

excellent power supply! where can I find a stabilized 10 kilovolt 500mA
5 kVA, that is going to be expensive. Properly Spellman.
@@KaizerPowerElectronicsDk I know Spellman, but the price is like a rocket

@@zilipoperyou could remove the cascade voltage multiplier from that xray transformer and put the transformers in parallel maybe??
@@T2D.SteveArcs this X-ray tank is 50 kW 100 kHz and 90 kW peak, I don’t want to break it and redo it
