[sdiy] PAiA 2720/R rebuild

[Dave Brown]

In case anyone is interested, I just was given a PAiA 2720/R synth that I
decided to restore.  A lot of the work was improving the construction
techniques of the original builder and dealing with the general degradation
of the electro-mechanical parts over time.  There is a list on the site but
the biggest issue was rebuilding the Pratt and Read keyboard which meant
everything had to be disassembled.  The wood cabinet needed some TLC but the
only improvements that I made were the increase in PS filter caps and the
replacement of just a handful of parts.  Most all the wiring and soldering
though had to be redone and it required a lot of cleaning.  The keyboard S&H
could benefit from a modern op-amp but I decided to keep it original.
