since it’s coming from just one speaker, just double check that.

I agree the mini is where it’s at! My mini is even smaller, with an 8″ Weber CVA8 Alnico speaker, which is a great fit.

With a 6K6, a pentode/triode switch, and a little homemade attenuator box between the output and the speaker, this a great practice amp.
