Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on www.pcbway.com/ I recently re-designed the PCB's to facilitate the replacements of the Selenium Rectifier and Filter Capacitors on the tube radios that I restore, and I'm happy to show them off here. They came out just as I had hoped, and I'm convinced that the changes were worthwhile.
If you wish to order your own from PCBWay, here are the links for both options. Please note that because of the odd shape of the boards, prices may be different than initially stated on the quick quote, so check final pricing before ordering:

Hope you enjoy the video.

Nice and neat pcbs. I half expected to see some plated slots so you can play musical chairs with the cap position. No actual music though.. or chairs lol. The rectifier could be untouched and keep the wires to keep the look. Your sneaky pcb does all the work :-D Keep tinkering :-D

Maybe you have mentioned it in a previous video, but is there a particylar reason why you choose to use 4 discrete diodes and not a bridge rectifier? It would take up less space on the PCB, and that could come in handy espessially on the smaler PCB.

It’s more a force of habit than anything else. Also, there are various pin spacings for bridge rectifiers, but with diodes you always fit them perfectly 😊

I am still surprised you can get the guts out of those old filter caps. I now had 3 old Philips in a row and 2 Erres, and with all of them the inside of those caps was just totally gunked up and stuck. So unfortunately I can't use these kind of PCB's :(
@electronicsoldandnew
@electronicsoldandnew Жыл бұрын
The idea of using these is if you DON’T want to restuff the caps. To restuff them, you can use a little heat to soften up the gunk a little and then it comes out quite easily.

Do you have any selenium rectifier boards for an old 1 and 3 volt tube radio?

The spacing between AC and negative pin is not a good design choice, honestly. You could swap 2 diodes and achieve much safer (and potentially less noisier) result.

For secondary voltages we only have to comply with functional creepage and clearances. Most definitely basis at best. Totally different story for primary mains voltages, something a lot of people mix up.
