Vintage Synth Repair

The safest way to get a dud CPU out is to cut all the pins as close to the
CUP as possible then take the pins out one at a time by heating the pin from
the component side of the board and easing it out with the iron.  Apologies
if you already knew this. Battery residue would make a great conductor :-)
try getting at it with an old tooth brush.
John.
