Ordered a new set of Sovtek 5881/6L6 tubes. Before I removed the originals, I took a bias reading. They were set to 50mA!!!
Installed the new tubes and pulled them down to 30mA. The amp instantly sounds better, and the gain level is now much more in line with what I thought it sound be. I am waiting on some new preamp tubes to get here and will post again after they do. Here's a quick clip. And yes, I realize that I have the bass up too much...lol!
A couple of gut shots when I had the amp open. I'm guessing this was a 2015 model... though I thought they had stopped making these in the mid 2000s. Anyway...
