What 300B tubes are you using in your VAC amps?

I am interested in the KR 300B's vs Sophia carbon plates and also the Full music brand but I think there the same as the Sophia. Any feedback on these?

Paladin.....even though I would like to purchase the WE's 6K is a bit much for me...more than I gave for the 140's in fact. I would like to hear thoughts on the KR's and other brands for the VAC's
I had the GD's and Cetrons in my 70/70 and the dragons were much better....I liked the Holographic soundstage and itamcy they projected. I purchased a octet of Sophia carbon plates and they were wonderful with a very lush midrange and very musical bass the plenty of punch. I have yet to hear them with my upgraded Accuphase C200 preamp and I think the transperency should improve greatly. I am sending the 7070 to kevin to upgrade....so I will use the 140's and will be looking to purchase 8 Sophia's or 16 of another brand.
BTW what do you like about the WE's and are they new production. I might be tempted.

Well I got a smokin deal on a octet of Sophia CB's so I now have 16 for my 140's......will report back.....I just couldn't pull the trigger on WE or KR's.

Alan....I was thinking about your detuning to 50wpc...could this effect the performance of the CP's. I ask because KH recommended the CP's over the mesh plates because he thought the carbon plates would be a better match with the Vac's push pull design. Did the factory detune the amp? My 70/70 does not have the tube sentry and I will have Kevin perform the upgrade soon. Kevin says it is a must for these amps. If you have talked to Kevin about this I would be intersted in his thoughts.

Hi Alan

About 90 or 100 hours and it should be WayWow time.

Enjoy

btw here in America Kevin does a fantastic job and has helped me tremendously....so we are lucky to have him right here.
