I'm contemplating a new amp build. I have a suitable donor amp to convert, and would like to build a high gain monster. I'll have 4 12AX7s available, so if I made a Komet Concorde clone one will go unused, if I made an SLO clone I'll probably be replacing two of the cathode follower stages with Mosfets. This is a future project - I have too many things stacked up to get to this for months, so I have lots of time to think it over. Which would you build, or would you go a different direction?
