Very nice score!

Today I have checked bias. It was set too high, 110% power dissipation of tubes. Must be some lunatic tech doing the job. I set it around 70%. It plays like crazy. Fantastic amp.

I liked it at about 34-36mA.

I liked it at about 34-36mA.

Unfortunately I have found that power tubes are not matched that good. The hottest one is running at 38mA, the coldest one at 32mA. So far it sounds good. I have one matched JJ quad somewhere in a box, maybe I will use them later, but now it's ok like it is.

I had it open so I took a few photos.
