Sadly, my religion forbids me from listening to music on youtube through my headphones... Yeah, tough hi-fi gods, I know; but my religion also has its perks, even though my wallet may disagree lol...
Meanwhile, a seemingly silly idea crossed my mind earlier, after reading up on the history of OTL tube amps since the 70s. Most of the "top tier" premium single ended triode OTL amps are "no feedback" amps, whereas even on the highest gain setting our MK III & IVs still have a 470k ohms resistor acting a negative feedback input. So here's the question: would it seem totally unreasonable to just remove that resistor? Bonus questions: would that screw up the circuitry somehow, would it actually sound better, and should ever so slighly higher "volume" be expected if that last bit of feedback were to be removed?
Just a thought; thinking and -very- light DIY work being pretty much my only purpose around here lol (don't expect crazy cargo ship sized adapters from me)!
As a side note, I wonder if I might not prefer (read "take more listening pleasure with") my Amperex OG tube than over my more premium Amperex US 6922 tube. The OG really has a special quality to its sound. Listening with the Heerlen-made 6DJ8 from the OG years, it's not hard to pinpoint what sounds great actually: it all boils down to lush -not warm- mids, sweet highs and chocolatey tight bass, all this over a dark, transparent et palpable background. I guess I may be more of a sucker for the tube sound and its richness than I thought huh (though I'm also a sucker for ultra detail and balanced FR)?
