bias
Post by nickyboy on Mar 16th, 2016, 11:19am

ok folks
I've just bought brand new sovtek 5881 tubes after blowing both fuses the other night.

The amp is 3 yrs old..the tubes were sovtek 5881.
Do I need to bias?

I recommend it, for sure. You can safely go to around 70% of dissipation but I think the Sovteks in my amp sound perfect around 60-65%.
