A Gold Lion 12AX7 that once was $40 is now $80 thanks in part to the maniacal autocrat in Russia. His name does not deserve my breath.

I just received my C2700 and so far I am pleased with it. I do have a set of Gold Lions that I picked up for my C2600 but never used. They were bought just before the tube fiasco began. I will wait and see how the factory tubes perform after breaking in for a month or so.

I mention all of this to point out that by my experience the Mc-branded and screened tubes are (usually) excellent.

Happy listening.

Bob

Pretty much the same experience here. I replaced all my Mc stock is C22/MC275 with Gold Lions after about 5 years, just because it was time. The bass improved, but it was not dramatic. Had I done only my pre amp, I'm not sure I could have noticed
