Thanks, Soundlock. I know the difference between the amp and preamp. That was just a faux pas.
You've convinced me to open the sucker and see what's what. Do you happen to know if the A-23 is the same as the A-21? I know it's twice the power but I'm wondering if the performance is equivalent. I also have two A-23 amps.
