"...the quiet ones were where they needed to be (phono input, Post RIAA amp, and line input).The not so quiet ones went where they didn't cause any problems (cathode followers and intermediate gain stages. By doing this we could use 95% of the tubes. You don't need a quiet tube everywhere and that is why RAM Tubes come in 4 grades." RM
? Tube Replacement Question ?
As a novice in the world of vacuum tubes, I have a couple of basic questions. I have a Audio Research SP16 tube preamp I purchased new in January 2008 & use on a daily basis. The tubes have never been replaced.
(1) When is it prudent to replace the tubes?
(2) Will sound quality deteriorate with age?
(3) Are there advantages of replacing the tubes with aftermarket alternatives vs. OEM tubes?
Thank you kindly for your help.
