I was biasing the tubes in my rebel 30. The 84 were slightly low about 30 so I got them up to 40 just right. But the 6v6’s were at 12 and I maxed out the pot to get them up to 34.6mv is this a tube issue or something else?
 
That happened to me changing to jj el844 pair of tubes which are slightly lower power 9 watts each instead of 12 watts and could not run them !
Different tubes could be high demand or low but too high unable to achive bias point is not good !
