    That is excellent work. Well done sir.
    "unjumped" is it a word?
    It is now:p I shall continue to use it..

    Are you planning on another enclosure? Something fit for the best electronics benches.

    No, I wasn't really planing to make a custom enclosure - I was thinking along the lines of mounting the circuit board directly to the front of the PSU so you can see all the electronics stuff.

    If I had a laser cutter I would probably make a case out of clear acrylic or wood, but as it stands, I haven't been able to afford one with my limited income. :D

    Hmm, wouldn't it be nice to have a lazer cutter. And the space for it too!!

    I 'ONCE' left an amplifier circuit open 'to see the electronics'........:(
    Sometimes when snipping off the excess leads from components, you can only find 8 out of 10.........
    You 'HEAR' the other 2........Lol..:p

    Wow Dan, that's great. Look how far you have come since you joined. You should be proud of yourself.

    That's a good point. Maybe I'll try and cover up just the back side of the circuit board where the fuses will be...

    Thanks Adam. But if it wasn't for you guys here on the forums, I probably wouldn't have come anywhere near as far! :)

    Man, it seams like it's been a loooooong time since I last posted! Been pretty busy lately...

    I recently acquired a 3D printer, so I printed out a front case for the PSU - I made a (final?) update to the project log under the "project log" tab.

    I'm impressed!

    You have done a really good job of this and you should be rightly proud.

    Only thing I can add really, is that in my experience, ALL electrolytics should be replaced at the first sign of any problem, or at some "unfathomable" problem. There was a big scandal a few years ago, that for something like ten years, many electrolytics ("paralylitics"???) had been made to a very poor quality and were not lasting long. Ridiculous really, as they are some of the less reliable passive components as it is...

    If you don't replace them - Especially on older items - You run a real risk of ruining a lot more components. Think of improperly smoothed DC, with peaks going out of the range of semiconductors for one thing. There's also a small risk of fires and things like that. Old TVs back in the 60s and 70s had capacitors right across the mains electricity all the time. So many house fires and deaths were caused when they dried out and caught fire. Thankfully a lot less of a risk now, but still worth changing them all, even if only one looks anything less than perfect.

    There can even be a slight problem from the inrush current on older equipment, because the plates of the larger caps have to form again. I used to use a PSU and a little jig I made from some wood and aluminium to reform the plates of all my electrolytics in stock, every five years or so. I've never heard of anyone else doing that, but it's probably because I had a large stock of them I got for almost nothing, from businesses that closed down. So I had some hanging around for a lot of years. It was very educational to use a regulated voltage supply and an ANALOGUE meter to read the current. You were effectively taking ballistic measurements of the current consumption and I got to lear a fair bit, AND filter out the odd leaky one!
