greets all - though there's been several of them i've yet to find one comprehensive thread regarding tact-switch replacement for mpcs. i'm hoping this thread becomes a summary of the process.
to be clear: i have yet to open the lid of an mpc much less go to work on the internal electronics - but i'm trusting there are others like me both dealing with decaying mpc's and yet to take the internal-electronics plunge.
the information i've been collecting here from the mpc-forums threads applies to the mpc 2500 but from what i understand extends to (most?) other models as well - any experienced users please feel free to add or correct info in this thread.
here's what i've got so far:
transport (play, stop, record, etc) tacts:
phillips head screwdriver
lead free solder
soldering iron specifically for PCBs (lower heat)
de-soldering braid and / or:
de-soldering sucker gun
needle nose pliers

do not pull the old tact switch out with pliers directly after heating-
always use a desoldering pump otherwise you run the risk of destroying the solder connections on the circuit board.
(modified step via sciguy)
Best way IMO to desolder is skip the solder sucker, and go for desoldering braid. Once you get the hang of using it right, you can get basically 100% of the solder out of the joint, and you can just pull the part out, leaving nice clean PCB holes behind.
anyone else have further tips / techniques / corrections?
