Calling all MC275 MK IV owners..............


I just set up my new MC275 and although the tubes have about 90 minutes on them, I'm blown away by the sound - I wish I discovered tubes 10 years ago.

Anyway, a few questions:

1. What gain level do I set the amp to. I cranked it all the way up but is there an "optimum setting?" I'm running these in stereo mode with unbalanced connections.

2. In a couple of days another MC275 gets delivered and I plan to run them in mono mode also using unbalanced connections. What gain setting is optimal for that configuration?

3. I have the amps on a trigger switch and noticed that on power up the tubes sort of glows a bit brighter for a second then settles back into the normal orange filament glow. is this normal?

4. What is tube rolling?

Thanks for all your help. I really appreciate it. Sorry if these questions are a bit stupid.

I use a C2200 into the MC275 1V and it is a killer, another way you may want to try is getting a VTL 2.5 tube preamp, if you don't need phono they are pretty inexpensive new and less here on the Gon. the 2.5 into the Mac is also a great combo.
