Best kt88 for VAC Avatar Super


Hi, my Avatars tubes need to be replaced, I have read allot about new kt88 tubes. Right now I'm considering between Genalex Gold Lion KT88 to Shuguang KT88-98.
I have got dozens of recommendation about the Genalex. With a short corresponded with Kevin from VAC I have been told that the Chinese tubes are prefers, and especially the VAC KT88.
Does anyone has an experience with that issue and can give me some recommendations?

I am a long-time VAC Avatar Super owner and have tried quite a few brands of output tubes and have found that the absolute best are definitely the Genelex Gold Lions, they do everything right from top to bottom. They are just awesome. Also a very good performer was the Ruby KT88 which I tried on the advice of a local tech. Next would be shuguang and then EH (great detail, limited bottom end).

The VAC tubes I have bought are very expensive and I don't see that you are getting anything better than you can get for less $$ from known and trusted tube vendors. Remember, Kevin values his time highly and you will see that in his pricing (can't fault him for that).
I buy my tubes from Jim McShane, he is great to deal with and provides top notch service. I just received a back-up quad as the set I am running now have been at it for over 1 year in my amp. I think you will find that they will work pretty well out of the box and it won't take too long for them to settle in (30-40 hours). I would never leave my amp on 24/7 for burn-in and always turn mine off if I am not going to be listening to music in the next hour. I was talking to a dealer the other day who told me about a customer who blew up a set of new tubes in a VAC amp because he didn't properly mute the unit when he was getting initial bias set. With new tubes I always start at lowest bias setting and let tubes warm up for 10-15 minutes before bringing up the right voltage.
