Re: [kawaisynths] k1rII fault ?
2016-01-02 by domgoold@...
never know :) and OS is known, @ v1.0
so...i took it apart. there are 3 surfacemount big ICs on the underside, couple of
smaller CMOS. everythng spotless.
the battery seems still good, measuring 3.18v, -which i think is spot on?amazing
after 20+yrs.
only 1 eeprom in a DIL socket, and i did take it out, came out easily -maybe too
easily? i cleaned pins lightly and put it back in;
checked it, still has a scratchy sound. it's calling patches very well, mainly
recognisable.
so that's pretty much everything i can check myself. no scope+probe here, and
i wouldn't know where to look anyway.
? some ROM decoding or clocking issue?
i don'tknow how to check capacitors..
i think this fault is either minor, or something very specific (soz to state the obvious, haha)
but it isn't total chaos, and may even have improved slightly; i'm going to plug the Remote
into it with TC's Kawai K1 mapping and abuse it a bit.
i'm thinking, this thing got packed badly, and then flipflopped a few times on post office
conveyor belts( if you still imagine there's a nice careful chap picking up your precious
parcel and carrying it from A to B...) - tell'em: bubble-wrap or forget it !
