In Reply to: RE: Need some guidance on my new M400-s mono amps posted by Tre' on June 17, 2021 at 14:08:04
Tre, I do not have a schematic and the owners manual is fair at best with minimal description on typology. This is pretty much why I came here to post for help. I came up short on really good technical info that could lead me in the direction of what type of build these are based on and how to pursue the ringing out of performance possibilities. I got them on a great deal new old stock and have owned other Opera / Consonance gear before and recently acquired an M100+ integrated to play with. These monos are very nice sounding out of the gate for what I paid and with my current gear.

@Tre'
Hope these show enough to give some indications.
The 12au7 is for sure the driver stage. It is cap coupled to the grids of the output tubes. The bias setting on the output tubes will not change when you change the 12au7 or the 6922.
