The only difference between the BT-4 and the BT-6 is the number of
tubes and the voltage capabilities. The BT-4 takes advantage of a
combination style tube where the single tube contains the pentode and
triode. Whereas the BT-6 uses a 3rd tube per channel and the pentode
and triode are in different tubes. The sound quality of both ampliers is
outstanding.
