Tubes for Vac Super Avatar ??

I replaced two quads in my VAC 220's with SED KT-88's from Tube Depot at a reasonable price, they sound great and are durable.

Zodiac, I have recently had qc issues with tubes directly from Kevin, but he has been good about getting replacements out but even those don't hold up. TVAD's advice is spot on from my experience.

Onemangang - I guess you really do love the VAC Avatar Super! What do you recommend for the brand and vendor for the pre tubes you mentioned. Thanks.

Onemangang's opinion does make sense to me when looking at a manufacturer's point of view. Kevin himself told me that he tries to use good tubes that are "readily" available. So from a "voicing" standpoint, he basically finds a good, readily available tube that works best in his circuit. He also mentioned that maybe 10% of the NOS tubes that he's experimented with might be better sonically than his stock tubes. He didn't tell me what those 10% were and I was reluctant to ask him. I guess tube rolling's the audiophile way, but it sure can get expensive in a fast way; but then again, VAC's stock tubes are pretty expensive, so what to do?

Grant,
Assuming I still have my VAC Musicblocs when the stock tubes begin to wear out( they still have some good life in them) I am definitely going to go the Penta or Shuguang versions per your recommendation. I feel confident that these are equivalent to VAC's stock power tubes, and there are good dealers for these who will sell them as matched pairs or quads.
