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.

Thank you for your responses – I already contacted Kevin at VAC but did not receive answer yet.
I decided to take another approach and ordered Shuguang Treasure 'Black Bottle' 300B-Z tubes from Grantfidelity (www.grantfidelity.com) in Canada.
This quite unusual tube (black bottle) is newly released and was tested on VAC Renaissance 140 amplifier.
I few weeks I will post a review of the tubes.
