Hi,
Can you tell the panel of esteemed experts here whether your P6 is
uniformly out of tune or are there regions of the keyboard which are
worse than other?
As CJP says these old analogue circuit are prone to drift when the
tollerances of the components start to change over time. If the tuning
knob is hard over to either the left or right this certianly is well
out of the original design parameters. There are special procedures
outlined in the service documentation for recalibrating the P6. Also
there are articals ad infinitum in this group which mention tuning
faults which can occur to the opto-coupled feedback arrangement on the
key assigner board.
Cheers,
Andy
