Emission Labs EML 30B-XLS tubes in VAC Ren. 70/70?


I was considering re-tubing my VAC Renaissance 70/70 amplifier with Emission Labs EML 30B-XLS tubes. I talked to the tube dealer who advised against use of these tubes in VAC due to automatic bias in VAC amp.
He suggested that I use "less expensive" tubes.
I would like to verify if he is correct and in case he is, what would be the best brand of 300B tubes for this amp?
Thank you i advance for help in this matter.

I believe (not sure) that its actually the other way around. The 30B-XLS tube is NOT a drop in replacement for a 300B. I know for a fact that Cary says they are not acceptable in their 300b amps. I would check w Kevin Hayes or his tech. Quick phone call is all it takes and as expensive as 300bs are, the amp is WAY more $$.
