tube rolling Mac 275 mk IV


I have had a Mac 275 mkIV for about a year, and would like to try a few new tubes. This has been my first foray into tubes and do not have any experience doing this.

I am currently using original Mac supplied tubes, and would like to hear what has worked well for others. The rest of my system is comprised of a Modwright 9.0 SE pre, Ayre CX7 cdp and SF Cremona Auditors. I appreciate the comments and suggestions.

If its in your budget try replacing the 12at7 with telefunken ecc801s first, I noticed much better top end with improved resolution and clarity.
Genalex KT88's work very well with my mc275, go for the GEC model and save a few hundred on a quad. Telefunkens and bugle boys will work well with the 12ax7 and 12at7, many choices there depends on your budget. Get rid of those stock chinese mac tubes and your amp with come to life.
