So interesting read all around, I’m pretty sure I’m not back feeding interference back into the power grid since even without an inductor, I’m almost sure any signal returning to the PS would be blocked by the rectification diodes since AC would be blocked in that direction, sorry read up again on Diodes and I kinda mixed up Switching Noise with AC (Cree has a 0 Nano Second Delay so I guess I probably don’t have to worry about switching noise though). Also I don’t think the amp has any noticeable stray capacitance outside the circuit so the chokes I’m using (I’d Imagine) are for differential mode suppression inside the circuit itself in order to remove any signal noise trying to go against the DC powering the Plates (I’m not that good with technical speak, I do and hope I don’t mess something up, and either it turns out great or I need to buy new parts for another test). I read upon your link and there’s also this page here explaining other types of noise in a circuit and where to look (https://micro.rohm.com/en/techweb/knowledge/emc/s-emc/01-s-emc/6899) as well as different capacitors and X vs Y Safety Capacitor and their Purpose (https://www.allaboutcircuits.com/technical-articles/safety-capacitor-class-x-and-class-y-capacitors/).
Honestly though I think alot of these concepts may come more into play with SS amplification as well as MOSFET/Transistor Regulated Power Supplies (Look at the Mainline For Example). With Amps using CRCLC Power Supplies, I have to imagine some of those issues may not be present or to better put, different issues are present in such a design. I could have gone the Mainline route and made it transistorized but there’s a particular way I want this amp to sound and making the Power Supply regulated that way may have not been what I wanted, idk alot of people say the Mainline is a bit too SS sounding, although I am using Diodes instead of Tube Rectifiers for Bass Response, Internal Tube Resistances giving a bit of Bass Sag due to how the amp works at different frequencies when getting current from the Power Supply or something. I’d love to test a tube rectifier but those things are really expensive, and I really don’t want to spend 100 dollars on a component that might not give me the sound that I like, there are cheaper rectifiers though but I think I’ve read enough forms to see what the majority distinction is between Tube and SS rectifiers.
Besides so far the amp in prototype sounds pretty good (more to my tastes compared to some other stuff I’ve tried, and WAY better than what my modded Darkvoice can do by a very large margin in both power and dynamics and just overall sound, although I still love my Darkvoice to death since it was the first amp I modded), and ngl I feel that if I start to try to look for noise the amp doesn’t have I’ll go crazy since alot of the amp is based on schematics I read and reproduce, test out, and then adjust what’s necessary for the tubes in question as well for what my design needs and preferences for functionality and sound.
Besides the amp prototype using worse components and no inductors was dead quiet at least, unless noise past the 20Hz-20kHz could affect me in some way (I’ve read theories but idk)?
Thanks for the websites though, really interesting to read up on some of this stuff and it doesn’t hurt to learn a bit more here and there, besides It’ll also help making sense of other schematics quicker (Might try my hand at something electrostatic when I get my hands on some design plans, although I don’t own any electrostatic “Earspeakers” so that may be for the future).
Oh Also just for a reference, The amp I’m building is based on pictures/schematics/design/concepts/sound of the following: Bottlehead Crack,Bottlehead Mainline, DNA Stratus, WOO WA22, WOO WA33, ampandsound Kenzie, Eddie Current Super 7, Felkis Audio Elise + Some Guitaur Amps I’ve had the chance to play around with and disassemble/reassemble. Its surprising how much DNA all of the amps share, even guitar amps. Obviously they all have their way of doing things, different Power Supplies, CCS vs Resistors vs Inductor Plate Loads, Tube Types, Transformer Voltages, etc as well as Tube Phase Splitters in Guitaur Amps and other stuff, but there is a certain familiarity to all of them, I just can’t put my finger on it. Thanks again for the Reply tho.
