Question for BAT 6H30 tube owners


I'm a long way from needing to replace the tubes in my BAT pre, but wanted to ask about the cost differential in buying them. I've seen them for $50 per tube and then the MUCH higher cost that BAT or one their retailers charges. I've read that Victor has a large stock of the 6H30's..are they different or a better tube than buying for the lower price? Thanks for your thoughts and/or experience.

I spoke today with Victor Komenko of BAT about this. He mentioned that they are almost out of stock of the NOS 6H30s and would shortly be converting to new production. He stated that his NOS versions are also available in the general market, and are designated 6H30PI-DR. He also mentioned that there is some junk out there to be avoided. He is unaware of the gold-grid version-- his versions have white grids. I can report that the Sovtek -EB version I acquired from Tubestore.com for my VK75SE sounds fine. So there it is.

Electro Harmonics makes the gold pin version of the 6H30. Works fine with BAT.
Even the REX does not come with the NOS DR tubes, only the Sovtek current production 6H30. The remaining DR tubes that Victor has will be sold by BAT separately for whatever the market will bear.
to all out there the 6h30 is now so much in demand that
ELectroharmonix -which is indeed a part of Sovtek
a little better quality control I am told. To get the most out of the tubes here is a little tweak I found and this applys to all connectors ,1st go to cvs or any drug store get 90% alcohol clean all connectors and pins , Furetech sells Nanafluid which is pure gold particles this fills in all the fractures in the pores of the metal it makes anything that comes in contact a far superior contact,for in a sub atomic level there is electrical arching,this stops this .
the tubes now sound like a good vintage or DRs and a bottle comes less than 1/2 full is $125 but well worth the effort the best on the market I have tried every top brand out there this is a permanent fix !!
