"The large bottle type needs more negative bias then the EL34."I'm not sure I agree. The tube specs don't indicate that should be the case. And my experience has shown that the variance from batch to batch and tube to tube of either type (6CA7 or EL34) is the biggest difference in bias required. I have plenty of hotter EL34s that need more negative voltage than the cooler 6CA7s.
