I have read that some MM amps are self biasing, I know with all previous amps I have had them re-biased whenever changing the tubes, however I wanted to know a) are the MM 210 RD One hundred amps self biasing and b) if so does this mean providing I replacing with the same type (matching pair) I don't need to get the amp re-biased? Many thanks for your help!   Mike Kaus (mm210) Username: mm210 Registered: 05-2006 Posted on Tuesday, July 02, 2013 - 06:26 pm:    No---amp has to be "biased" but the system is pretty forgiving. Get a set of tubes that are "matched" and follow the "bias" instructions for the SS driver amps.
