Managed to eliminate ghost notes with PPIMV

Not sure if this has been posted before, but I just installed a fixed PPIMV in two of my amps that both suffered ghosting qutie badly. Thought it might be useful for those who have had trouble in this regard.
I basically replaced the 220k resistors with 150k/68k pairs and the ghost notes are completely gone. The amp is still plenty loud and hence my attenuator doesn't have to work as hard for sane volumes. To my ear, a PPMIV and an attenuator works better than just one method. Hang on, getting sidetracked....of your amp suffers ghosting and it annoys you, give the above a try!
