Amperex Bugle Boy 6CM4

Have just been trying these little gems out as driver tubes in the McChanson 6L6 marzE. It's only recently that I realised 6CM4 valves were equivalent to EC86s. These drive very very well and would have been in my top list when I did the EC86 shootout if I had them at the time. I expect they may be quite difficult to find, but if you come across a pair I don 't think you'll be disappointed.

  1. Thanks for the notes. I tried about 12 pairs of Ec86/E86c variants, and the best to my ears were Telefunken E86c tubes. Unbelievable stuff.
