Tubes for Cary SLP-05

Here are some other Sylvanias I have used and liked as much as the metal base and are a little cheaper. The 1952 tall bottle ("bad Boys") and the 6sn7W tall bottles. Which are pretty much the same as the metal base only plastic base. You can get some general info one the 6sn7s at www.tubeseller.com
Also if you do a search on www.head-fi.org there is a huge thread on the 6sn7 tubes. Type in.... The reference 6sn7 thread...lots of good info.

Here are few combos of 6sn7s that I have used and think would meet what your looking for in sound.
Ken-Rad VT-231 (black glass) in front of Sylvania VT231s.
Sylvania 6sn7W metal base or black base tall bottle in front of sylvania 1952 tall bottle bad boys.
Ken-rad VT-231 (black glass) or 1952 bad boys(sylvania) in front of any of the sylvania 6sn7w tubes.(metal base, tall or short bottle) I've used these combos alot and have found them all very nice. I also like the TungSol roundplates and National Union Black glass alot but not sure if if these are what your looking for. Worth owning and trying though.
