If you get the BC22 also pick up the BC95 interconnects to connect the amp to the BC21. They all go together wonderfully.
Blue Circle amp with TSM
I got the Merlin TSM last month and feed it with my 300B PP amp with 22W. I feel that the 22W was under power for my Merlin after listening for this period. Thinking of replacing it with the BC22, which I am using the BC21 pre now. Any comments or other amp that suit the TSM best.Regards.
