Thanks everyone for the tubes suggestions. I see that almost everyone recommends the Sylvania 6SN7WGT brown base. I have seen these all over the map as far as price goes. Can you guys tell me what a fair ballpark price is for a pair of used ones that test really well. I'm not a big stickler that they have to be completely new and unused, and would actually rather to pay less for slightly used ones. Also, are there any other tricks to look for when seeing this tube on ebay for example? You guys are the best.
As for the addiction, and no hope comments, all I can say is that the best defense for my budding addiction (or lack thereof /denial) is a wife and full-time daycare. If anyone is in desperate need of an intervention, I can ship both (the kid as well) in exchange for your best tubes!
