Best tubes for BAT VK5i, help please


Want to upgrade to some better tubes for my BAT VK5i. I don't want to spend the 2K for the SE series and I think I can improve the sound with a tube change out. Any comments as to where I can go or who to call for advise would be very much appreciated. Thanks to all.

I have a 5i. I think its soft start feature is supposed to make it less hard on tubes than many other preamps, but I've never tried anything but the Sovteks.

I've heard that the Amperex/Tungsol combination is supposed to be "the" combo to use with the 5i. Kevin can hook you up, but he's be no means the cheapest supplier around. Good luck.
Paul, I'm only going by what Kevin told me. He would not sell me NOS tubes for this stated reason. Not sure of the validity.
I bought NOS from Kevin a few yrs back. 6 Amperex gp 7308's (there are 2 positions that aren't critical to the sound) and 2 Tungsol 5881's. They lasted for 2-3 yrs. I've been running the 7308's in the vk5d just fine. You might want to try the older version of the Sovtek 6992 he carries. BTW, Steve at BAT had no problem with using NOS, but I believe Viktor likes the Sovteks.
