I did some research and some calculations and came up with the design below for a 6CK4 amplifier. I was going to use a 12B4A but I can get a whopping 1/2 watt more out of a 6CK4 so I'm going in that direction. The design may be overkill but that is what I like. I only plan on building it once so why not? Anyway I am hoping for some thoughts and constructive criticism from our more learned members here.
