Need tube 101 info


Ok I'm new to this tube preamp world and I'd like to know a few things. I've acquired a BAT Vk-3ix that needs new tubes but I'm not sure I understand what tubes do what and how to properly "roll" them. I don't want "bright" tubes but I'm completely at a loss as to which brands I should be looking at.

Also what do the two tall inboard tubes do, and what do the small pairs to the left and right do?

When you get a matched pair of the small tubes does one go on the left and one go on the right?

Can you mix brands on the left and right. For example can you have brand x and y on the left and x and y on the right? Will that hurt anything? Or should all be the same brand?

I know these may be simple questions but I gotta start somewhere I suppose.

Last, try this site for basic tube info: http://www.vacuumtubes.net/How_Vacuum_Tubes_Work.htm. I know I've seen another site that had good audio-related tube info but I can't seem to find it right now. Maybe others will recommend a site. I'm not sure a conversation with BAT will be helpful re: NOS tubes. My understanding is that they don't recommend using NOS tubes. However, I had an email conversation with Viktor when I first bought my VK-3i and he was very gracious. - Dick
Good deal. Yes, the guys who run BAT are Russian. Don't let this experience put you off of tubes. The rewards are often great and tube preamps aren't really all that much trouble. I'm sure yours won't be either, once you get it running properly.

You had better be careful or the level of hiss in the house will go up dramatically and the tubes won't be the only thing that is ringing!
