RAM Super Low Noise 12AX7

David99, I hate to tell you this, but there is a chance that the Rogue 99 cannot be made quiet enough for you with any 12AX7 tube. If Mark has installed the quietest tubes he has, and they are indeed the new Sovtek LPS, there is probably not anything more you can do on the tube front. I would be willing to bet that the RAM tubes are re branded NOS. Who knows what brand or performance they are, unless you get them and have the experience to look and determine what they are. I am a tube guy BIG TIME. I own about seven different brands of 12AX7's, and several variety's of that type within the brands. The Sovtek is not the ultimate sounding 12AX7 in many applications, but noise is NOT a problem in any of my experiments. I would welcome speaking with you about your system's noise problem in general. There are a dozen other things that can contribute to the "rushing" noise that is not directly related to the tube compliment.

Albert, please contact me at davebauer@webtv.net and I will explane all I can think of. Thank you so much.

Your Dealer is an IDIOT, RAM tubes are some of the best tubes out there if you can find them there over a hundred dollars each

Those are brand new in there original box, not NOS

Being a 20 year old thread, even brand new tubes can be called NOS.
