It has been argued to me that higher end audio component companies are making upfront decisions on the type and quality of the tubes in use. So, if you have a high end product line, one should expect that the high end line is using the top quality tubes for their product and there shouldn't be a need to upgrade tubes - they were already upgraded in the first place. Just let it ride. I understand the desire to dink with sound and search for improvements. We all do it.
Expanding questions about tubes in a preamp
Hello to all...
Started with a (helpful) discussion titled "How to select tubes for a line level preamp"... Expanding questions that have generated from that...
Have learned that hum/noise from tubes is a major consideration - now trying to figure cheap ways to address quieting the 12AX7s and the EF86s.
Would like to try "banding" the tubes with rubber ring washers - one?two?three per tube?
Where should the rings be on the tube: Top? Mid? Bot?
Can you over dampen a tube?
Knowledgeable tube users/ Masters input/suggestions please...
