Original vintage PCBs for the project? That's the icing on the cake.
Looking forward to the rest of the series
Yes! The original Elektor PCB's from 1982, sent in by a viewer. Thanks for the subscription and thanks for watching.
I build this one in 1982 , modified it to a 0...50V 0....5A and 40 years later it's still my main pover supply with analog metres.😊
That's wonderful to hear. Has it been a reliable supply? Would love to see some photos of it.
It has been very reliable, had only to repair twice during its lifetime and one was my own fault.( Burnt out the sense resistor by using the wrong banana socket)
Could you take some photos of it? Would love to show some photos of your one on the channel - info@jazzyjane.co.uk
i buildt lots of kits back in the mid 70s and just started building kits again a couple of months back,glad to see that kit building is still a thing :)
we had many of the same electronic magazines here in Norway as you had in the UK back then.
I will be reviewing some of the more popular electronics magazines in a video soon. Thanks for watching.
Now that's a trip down memory lane, i built their 12v 5amp power supply waaay back in the early eighties, served me very well, managed to leave it behind when i changed jobs, ah well!, look forward to the rest of this series,
Yes, we are going to modernise it a little bit along the way. Thanks for watching.
Cool project, power supplies are always fun to build, and are quite useful when done.
We gonna see how this build goes and if it works well we might revisit it in the future and add some more modern features to it. Thanks for watching.
Awesome kit build! Love it. Thank you for sharing this approach, I always wondered about elector! Nice design people from back in the day.
There have been quite a few electronics magazines published over the years. I will do a review of the main ones in a future video. Watch out for that. Thanks for watching.
@JazzyJane_uk I hope you do popular electronics and maybe readio electronics, from me in the usa, it was 2 of my favorites from when I grew up. I know your in the uk, but I hope you read those as well. 😃
Great content and tee shirt Ohms LAW brilliant, I have one in purple 👍👍
Thank you and thanks for watching.
Hello from Belgium, I build the same powersupply, but used 6 output transistors for an output of 6 amps, still works perfectly!
That's great. Have you got any photos of your power supply? If not could you take some?
I would love to show some photos of your one on the channel - info@jazzyjane.co.uk
Thanks for watching and thanks for subscribing.
Linear variable supply is also going to need a decent heatsink. Also can you find different colour LED displays so maybe voltage can be red and current green
Yes, I already have some power transistors mounted on suitable heatsinks that funnily enough actually came out of I think either Farnell or Thandar power supplies. They were bought off eBay just as transistors on heatsinks. I thought they might come in handy one day for a project and sure enough they have.
I'll look into different colour LED's but I would also have to get a new piece of filter material for the meter plastic housings as well. Might be possible. Thanks for watching.
Subscribed for this one! 👍
It's going to be an interesting project. We will be making a few tweaks to the original project but it will end up being a quite decent bench power supply. Thanks for the sub and thanks for watching.
Nice build JJ, looking forward to part 2
Yes it's going to be an interesting build, with a few tweaks to the original design. Thanks for watching.
That does look fun, have axial electrolytics finally gone out of production? it was on the cards late 80's but i was still seeing them from decent brands 6 years ago via digikey and mouser. the snap in caps are a good solution i may have tried to use a radial non snap in type with some heat shrink to keep the same look. it is amazing how small electrlytics have become.
A few people still make them, like Vishay, but they are very expensive. Everything is radial these days when it comes to aluminium electrolytics.
I suspect that axial leaded components came about during the days of valves where components were spread across tag strips so needed long leads either end.
When printed circuit boards came along it made more sense to use radial components where the tracks of the PCB's were the legs so were not needed on the capacitors and axials started to fade away. Thanks for watching.
Jazzy Jane I'm totally in love with you and your t-shirt where would I buy one ❤
Thank you. You can get one on Amazon, in different colours too:-

Thanks for watching.
Great Idea!
For an alternative pcb and kit search '0-30V 2mA-3A DC Regulated Power Supply DIY Kit' from the usual places (YT deletes my comment if I name any?!) It's extremely cheap!
Your videos will help with advice on Heatsinks, transformers and hardware as these are not include in this kit.
Cheers.
I'll have a look at that. See what it's capable of. Thanks for watching.
Unfortunately those RED PCB based kits have some flaws and I can not recommend. Electronics dash lab in the community projects you will find improved version of the afore mentioned.
