SE amps

Post by jestaudio »

still toying with the idea of a SE based on either a 6l6 or a el84 but am now thinking about maybe kt66 as well, is there a optimal OT that would suit al opf the above lus i assume there would be some happy meduim on screen voltages that would enable me to use all three valves at will.

Should do as long as i can keep all the loads correct when switching between tubes, under ideal circumstances i would want to use the same tap irrespective of tube selection but i can't see how i could get it to work

This one can run octals from 6V6 all the way up to a 6550 by adjusting the bias resistor.
