I've been messing with electronics for most of my life both professionally and for fun. One rule I was taught early on is that you must always employ a current limiting PSU for any new build. Whiskers, misplaced components, dry joints and VERY VERY seldomly faulty components can be very depressing, 99% of the time the fault has always been of my own making and it's saved me on many an occasion.
For old mains transcievers and receivers I have a variac with 2 light bulbs in series. If there is a short, the bulbs burn brightly as you wind up the variac. It should be straightforward to build a low voltage version of the same, I might have a go at that.?

If you?re a maker, you need one. Can?t put enough emphasis on that recommandation.
Especially considering the fact, that I bought mine for 60€ in a Reichelt Sale. They?re absolutely not expensive.
Right now, they sell it for 74,43€ (I have a "Peak Tech 6080A")
