The 6V6's are great, starts cranking before the roof takes off. Of course a Weber Silver Bell Alnico 75W helps .. instead of the G12T-75 Celestion which is horrible in this amp.

Bob is the man.

Transformers inside amplifiers were not originally designed to be in there, and the tube was not created for the guitar amp.
ANY recommended idle current is a guideline and in no way a necessary requirement. There is no skeleton key for any tube amp.
