studio 440 key replacement

studio 440 key replacement

2009-01-31 by synthdrome

hi all ,

someone here posted a digikey link for the 2002 keys.. these keys also
fit as drop in identical replacements for 440's. i just did the
majority of mine. its fantastic. 

OMRON-B3J-1100 is the manfacturer and code for the non led switches.

also looking into seeing if i can just find the 12mm switches and not
the covers or hinge base for it.  the switch and cover and base all
seperate into re-usable pieces..


thanks!

a word of caution... if you decide to do these.. be EXTRA careful on
removal. the foil on the pcbs likes to lift when you heat you heat the
connections even at lower temps. so it makes possible shorts in the
switch circuts. 

im having ussues now with a short hat happens when you hit the pads
harder.. i think soemthing i s barely connected. (maybe a crack in
solder or circut trace having something to do with kit/bank/alt
parameter buttons...it eventually locks up the 440.

any ideas?

thanks!!

found the issue. on the auto repeat key. slight crack in foil trace. 100% now.

wow a 440 with fully working sliders, scsi and all keys (with one press only..)

worth the time and costs.

thanks all.
