CJ mv60se/11a
is the mv60se really better than the older 11a? can one use el34 in the se, without rebuilding anything or so? the CJ site doesnt mention the se model at all, is it just a rebuild done elsewhere than the factory? how do one do the convertion from ultralinear to the triode operation, and why would one do that.. yes, im new to this.. but about to try the world of tubes
