Thanks for advice!

The amp has an auto-bias circuit, so I cannot check it. Strange thing is when I put other quads (expensive GEC KT-88), one of them becomes red-hot in 3-5 minutes, and in different sockets at that! I will try to borrow a quad of Sovtek KT-88 tubes from a friend and will see how they behave.
