Mikesinger: What's the diff with the r version?? I didn't see the 6h30's on their website call em?
I retubed my vk50 se after 3.5 years of use. Could hardly tell a differnce. The original tubes were still going strong I suppose. I did buy my replacements from BAT, I didn't mind giving them a little extra $$ b/c I like the company. Anyway, I'm guessing 5+ years before you should really care about changing those 6h30's.
(fyi, I could tell a bigger difference by cleaning the tube pins and sockets that new tubes-which is something else to try for you)
