6SN7 suffixes

I'm using 6SN7's in my Atma-sphere equipment. I was curios about the multitude of letter suffixes that follow the 6SN7 tube type.

Charliee, I use Andy at Vintage Tube Services, as I feel that he is the "go to guy" for all things tubes. I usually speak to him over the phone, so I hadn't been to his website since I switched to a high speed cable modem. Loading with my previous molasses slow modem speed and ancient computer, it could take awhile to download. Yeah, there's some good stuff there. Here's a link, so others can see why those want tubes go to Andy: http://www.vintagetubeservices.com/
