Related Questions and Answers

Q: 1. is this a low noise tube ?

A: I believe it is. I changed out the tube in my preamp before even using it. It is the Telefunken equivalent to a 12AX7 which is a industry standard preamp tube. Telefunken has been in the high end audio tube business for many many years. I just believe this is the best preamp tube available. The tube i had pulled out was supposedly a selected Chinese 12AX7. Although I do not have the measuring equipment to measure any differences, I am completely satisfied with the ECC83.

Q: 2. Will the matched pair still be a matched pair if I replace it with two NT45-O omnidirectional capsules?

A: If you replace one of the RODE NT5 Cardioid Studio Condenser Microphones in a matched pair, it should be very close, but may not be identical to the other mic.

Q: 3. would this be a good replacement for the tube inside my akg perception 820 mic?
