ANYONE heard the old 1957 ge 6550,s

GEE- Ya mean tubes that were made back in 50's sound better than the junk that's being manufactured now? A statement like that is certain to get a LOT of people riled on this site. SURELY: It's just your imagination, or wishful thinking(because you spent so much on those NOS tubes)!! Actually: The GE 6550's were the tube of choice for the Premiers Eight and Twelve. If they were more readily available, I'm certain Messrs. Conrad and Johnson would still be supplying them in their amps(connoisseurs that they are). What NOS 6922's will you be experimenting with? Hopefully you will compliment those excellent amps and GE's with some Siemens CCa's? Enjoy your music!

OOPS- Make that, "excellent amp"(singular).

I believe your comments, I use almost 100% NOS tubes, but one thing about your post confused me.

had the Sovtek 6550,s winged C

Which was it, Sovtek, Wing C or both?

thanks guys , yes installed siemens cca in input , unbelievable how good those ge 's are, friend , an engineer has been collecting tubes since 1970, has probably 15000, he tested 85 to give me a matched octet, plus 2 matched extra backups , ive been working on him ayear to sell 10 for a $1000, very pleased
