Re: Neat power supply!

I heard that some switching power supply when they fail they may make extensive damage because of leaks of AC, at least this what I was told. In some appliances that had noisy switching power supplies, I wrapped them into aluminum foil and added a ferrite to the vdc cable (wound many times). In the worst cases I connected the foil to ground. I solved completely the issue.

Ordered it and will try. I needed a variable PS for some other purpose.
For bitx I use one of the many bench power supplies in my collection.

Earlier I modded a laptop charger to make it variable but without display.
for 12 bucks this looked like a steal with display!
