You can see the other bits added over the years... Do I upgrade to digital displays...? I think I'd rather build another one, this unit works, although you do need a multi-meter to get really accurate settings. But the gauges are spot on, it's only when you require "point" of a volt... :)

If you're putting it up for a vote: No! I love the analog gauges.

Thanks! I'll think I'll keep 'em :)
Totally agree about the over-shoot! I've killed many a circuit forgetting about disconnecting first!!... I lived with it for a few years, but when I hit my apprenticeship (after blowing up a great circuit which took ages to build for work) I was straight in there like a thing possessed... Relays, bleed resistors, snubbers etc. :blah: But really the design was flawed from the start, could do so much better now. But it's my favorite piece of equipment and most useful thing I've ever made :)
I hate to think how much it cost the CEGB... (the mighty Central Electricity Generation Board... back in the day of publicly owned power)

"sort-of-accidentally" my butt. I know how these things work :) You're in good company, no need to hide.

I'm just saying, that "Make an offer" thing is dangerous, especially if you forget about that offer you made on a 3650S when you see a nice TW5005 with a tempting "Buy it Now" price!
Thanks for sharing those PDFs. If the CC and CV modes function properly even with the limit lamp always lit, I'd suggest starting at Q12.

If those analog gauges work keep them :) Not too many of those around anymore. Gives your PSU this "OLD" feel...
You don't always need super accurate readings after all..
Damn this thread, now i want to build myself second PSU...
