how about opening a new cap spec thread instead?
Tony,
I think what he means is that some transformers has different ratings. Eg 0-220vac and -10-0-220vac.It doesn't matter a lot because the mains might differ that much,

btw, some years ago, i reformed two sets of caps, one pair rated for 50 and another for 63v. guess what, the 63volt unit reformed to 77volts with current leakage very minimal in the microampere range...😎
Tony,
I have got Siemens 100v caps coming from a 50v rectifier that i have reformed that is testing almost 10% above their rating,they are 30 years old. I haven't tested their ESR, but I think they will still be OK.I have used some of them before, I have had no problems,

Nice. 🙂
Where did you get the pre-perforated steel panels?
Are they normally used to build storage racks or something?
They sure may be an option for home builders; the most difficult part is the "mechanical" one, not the Electronics.

thanks!
cut out of big U-profile
I think it comes from scrapped shelves for industrial mains wire
BA1200 pcb layout
I drew this just for fun, and will build at leisure time, ..
Thanks willy and first Mile ..

Your pcb dimensions is out of standard for use with 3U standard heatsinks dimensions must be 265x112mm and distance from outputs must be 96mm.

Sure Mr. Mile... why not? is that dimension given on rizqi pcb? if not please post the pcb with new dimension required for 3U heatsink so i can resize it accordingly.
