Beautiful piece of work, Kerry
In the recent months I've been slowly working on my T2, ended up rebuilding the entire amp board with mostly new parts. Just in the off chance that it was something in the board itself which caused the noise I was hearing. Thankfully nothing blew up, the batteries adjusted to 741V, and it plays music. I could still hear a background noise in it though. Having listened to George's T2 as well I was all but convinced this is just the normal noise level for this amp.
I asked JoaMat about his solid state inputs for the T2, and he was kind enough to send them to me to test out (thanks!). Amazingly enough they worked. The amp is still not utterly dead silent, but it's to the point where it's below the background noise level of my room (which is as close to silent as I can make it). I've also ordered some heatsinks for the 2SC3840s so I wouldn't have to worry about them getting too hot.
With either input set though, I've been having some sporadic noise on the right channel. Sometimes it's a random noticeable "pfff", sometimes it gets stuck noticeably louder. The latter is usually solved by unplugging/replugging in the headphones. Very strange. Aside from an overlooked loose connection or a bad solder joint somewhere I'm not sure what it could be. Anyway please excuse my blurry photos.
