"A $3.00 tube went up and up, and no would admit it was just plain, but instead resold them as THE wonderful, highly sought after "Bad Boy". Well guys it is a plain $6.00 6sn7, period. I have several stock picks for you, by the way, if you are interested.

Try a 1940’s metal base Sylvania or the Russian one, and tell me how great they are next to this 3 hole folklore."

which Russian one are you referring to? I didn’t realize any Russian tubes were even in the running.
