Not sure about the hum, as it could be a lot of different things, but it sounds like a ground hum from your description. So, you may want to try swapping out the tubes to see if it might be one of them causing any issues. You mentioned the extra set of KT-88s, but do you also have a different set of 12au7s as well? In my experience with the amp, sometimes the power tubes will hum and the signal tubes will hiss if they have a problem, so maybe try the stock again to see if it goes away?
Yeah, the 8200 has a ton of power! Just slightly below 9:00 is where I generally keep mine and even lower if it is loud/fast music in general as well, around 8:00. Several owners here have swapped out the pot for really good aftermarket options and have also put in resisters to get more movement control out of the pot. Maybe one of the users that did will respond, but you can also search this thread for some different options that have worked for others. I still use the stock option, but I am mindful of the extreme gain, especially when someone is trying it out for the first time and isn't familiar with the amp. I had a buddy that jumped on it during a meet without talking to me first, plugged in his HD800, put the pot to 12:00 and then hit play... wow was he surprised!!
Hello all,
Dimu wrote about some upgrade of Elekit 8200 for using tubes E80CC. What did he tell about?
Thank you for advice.
I was wondering which mode people were using based on experience - Ultra-linear, Triode, or Pentode?
I did some upgrades later one by one, shamelessly copying Dimu’s build to a degree. (bigger rectifier to use E80CC tubes, volume pot upgrade to TKD, all resistor changed to ARMG, drilled holes for better cooling, Cossor 807 tubes, even hunted down the automative caps too).
When I’ve tried to put in the bigger 3A rectifier, I messed up something, the amp flashed and smelled funny and never turned on again.

Oh hell no! Everyone is getting a cut. I'm not saying it's a pyramid scheme, but it's a pyramid scheme.
It sounds like you need to get busy rolling some tubes... how long has it been since your last roll?
I've been abstinent for a few months, already feeling itch creeping up.
