In Reply to: RIAA accuracy in Cornet posted by Jim Hagerman on March 5, 2007 at 11:42:27:
Hi Jim,Thanks for the explanation. It makes perfect sense. It does however bring up another question of how to maintain channel to channel match. I believe that a channel imbalance is going to be more audible and an absolute variation from the RIAA response. Resistors and capacitors can be matched between channels to quite tight tolerances. Am I correct in assuming that tubes would then also have to be selected for very tight section to section match? How close a match and what parameters should be matched? Will the individual sections age the same?
I know, a lot of questions, but I am just trying to understand the implications of using the tubes on hand vs. buying tightly matched NO$ vs. tightly matched current production.
Thanks again for your help.
