Hi all.

Just finished my TubelabSE. Played a lot of music yeasterday :)
But i notice that my bias from PSU is very high..
After R6 i have 260 V (should be around 150 V). What could be the problem you think? Does it matter? I still adjust the 300b tubes to 70 mA (-68 V at grid)..

Many thanks //Daniel
