I have built a couple of subwoofer projects which
included a 12" speaker in a large ported box driven by an SS
amp to augment a small pair of floor standing speakers.
The L and R signal from the line stage part of the integrated tube power amp,
( used for most of the signal ) was taken out with two cables to two 22 k
resistors, and at the join of these two R is a mono signal, and this is then
fed to a high input impedance emitter follower transistor stage,

Don't these 22k resistors create a noticeable amount of cross talk, given
the relatively high impedances involved in tube amps? Why not include a
couple of high input impedance emitter follower transistor stages in front
of the resistors?
