The Philco 37-650 uses this same output push-pull design (using the
screen of tube #1 to get the phase inverted grid drive for tube #2.
Mine sounds fine to the ear, I have not even checked the matching of the 6F6's yet. Have not measured it for distortion or anything but it does
seem to work good enough.
