I found both the tweeter and woofer FCs wired to #175 choke and the 2k resistor that goes to the 6L6.  It's only supposed to be the tweeter FC. Also cap #164A was a 16uF instead of an 8.  I knew somebody had been in there before me because a few lytics had been replaced.  It seems like I gained volume from the woofer but it still distorts when you turn up the bass gain control.  So I've got more searching to do.  I ran out of time.  4 am comes early.
