I didn't know this had such impact. And it does as you're showing. Well, is not strictly polarity but you're right about the shielding of using the external layer for ground. The difference is not huge, but at Hi-Z inputs this is definitely noticeable. Thanks a lot for showimg this to us. Is good to learn new things for better noise performance.
Thank you! Yes, the name is a bit "click-baity", as in reality is better called orientation, not polarity, but nevertheless - glad you found the video interesting!!
@@TheDannVal I make a lot of recaps for vintage amps... The noise floor in those amps is more a "noise ceiling", but every little noise is added to the total amp output signal.
@YDKMPablo true! Especially in higher gain amps every little detail can help. Most manufacturers don't bother, so every time I have the chance with changing coupling caps - I do this. Thank you!
This was very informative, I didn't know about this peculiarity of the capacitor. I don't know how long it took you to learn all of this and I don't remember if I heard it from you or if you learned it yourself or studied at university but you know a lot. I would like to see similar videos about other components and maybe put them under one playlist later. Great job.
Thank you! Most of the smaller details I've learned thru the years and with experience. I have a technical background and went to related school, but I don't attribute what I know on tube amps to that. My grandpa was a technician and an engineer and I learned all my manual skills and basic knowledge by tinkering and helping him out. Then started building PCs and modding them and in my early teens I got in tech/computer science school thinking I would learn more, but turned out I was surrounded by book-quoting, non-specialists and asking for details and more info turned into arguments most times. Example with one of the teachers that was an ex radar operator, booted from the army for his mental state being iffy. Talking to him about Firewire ports, and explaining to him that it's not at all like a "bigger USB" got me a warning, a low grade for the semester and kicked off from his class for a few days. That definitely made me not love school, and around 14 I started playing guitar and at 15 started working in a music store, learning way more about people skills by skipping a lot of school classes. Playing guitar and getting in recording and production and especially building, running and maintaining small project studios (and the gear inside them) thru the years, kept my interest in the technical stuff and leaned more into the analogue stuff, considered "obsolete" tech. A few years back I really got into amp modding and building (first for myself only). Now it's 30-50% of my daily life. Cheers!
@@TheDannVal How much this relate to my own experience, I came to the computer academy after school because I could not get an acceptable score on the external independent evaluation, there were no good teachers, some of them were just recently graduated students and I didn't learn anything more than I knew myself. My grandfather is not so educated of course but he taught me everything I know in the basics, for example how to solder, where to solder and how to repair a simple thing like a lamp or wall socket. I don't know much about the schematics yet and I don't have an electric guitar, but I dream of buying one someday. Cheers man.
👍👍 love your technical write up’s and videos. Are you planning on making a separate series on your channel for these types of videos? Would be cool for newer followers, or less technical folks, as an educational piece.
@@stephenrainaldi1483 Thank you!! The idea is there, many planned videos but not enough time to shoot/edit everything. I will try to push for more content this year, but it definitely depends on my studio schedule! Thanks for the support!
Haha, I wish! Half of them were "dead" when I bought them and had to rebuild them. The Mark IIB (one that is sitting on the top shelf, disassembled) is another project amp waiting to get finished. The preamp used for the video is actually a client SP2C V2 C++ that just got finished.
Amazing, never knew that. I wish I had known when I built a phono preamp.
Thank you! In a phono pre I don't think it would matter as much, so you are good!

Excellent information, and well-presented!

I'll be using a phone charger from now on when I scope my caps, thank you for that tip.
Thank you! You can use everything that draws power from a socket. Even the power cable on your scope, hahah! Cheers!
Howdy.
Awesome !
Darn it hurt cranking my brain around this ...
Regards.
Awesome dude! I never even knew this! Appreciate the advice!
Thank you! Glad you found it interesting!

Some do and some don't. You'll have to test what you buy to make sure.
dude srsly.. how many mesas have you got? you a millionaire? :D
