I’ve tried the Two Stoke circuit with several different transformers, voltages and a bunch of speakers (ceramic and Alnico). They all sound different. Different speakers make a very notable difference. Those ceramic Jensens are my favorites with a Tele. If you have not yet tried the Weber break-in procedure (especially for that C10R), you’ll be surprised how it opens up those Jensens right before your ears in about 10 minutes or so. I suspect the new Jensen Jet 10 would also be a good, low cost speaker for the Two Stroke.
