Alright goons, I need your help. I was disassembling a phone charger (raspberry pi related project) and I nicked a 470uF capacitor with the dremel. I took off a bit of the outside rubberized coating and put a tiny gouge into the metal housing. I'm certain I did not penetrate into the capacitor proper. Can I still use this or is the cap compromised?

yeah seems to be on the low voltage side. I'll solder everything up and let it run, I guess. Hopefully doesn't take out anything else if it pops.

edit: Seems to be working so far. Have to run full-load tests yet.

Is this the thread where I can ask about Tubes and Tube amps?

My questions are decidedly electrical! I've got a pretty good understanding of electrical theory, and I just recently started getting into tubes. I've done a little bit of basic reading, but a book would be spectacular. I've just built my first kit, now I want to build a monoblock out of an amp I've found. Problem is, the tube markings have worn off (and also I have no idea what I'm doing)

My camera battery is flat at the moment, but I know for certain I've got 2x 6BA6 C6, 1x 6BE6 H5, 1x 6AT6, 2x 6X4 H1B, and the aforementioned unknown tubes. I've only managed to find two data sheets.

Are there any diagrams/schematics for amps I could build with these tubes? Failing that, is there a good primer on designing a simple B Class amp with these parts?

If anyone's interested, I found this book on tubes! It seems like it'll answer all the questions I had.
