JD800 key cleaning

Post by Tek » Mon May 05, 2008 10:22 am

My JD800 has developed several defunct keys after being left unplayed for a while. I've cleaned several keyboard contacts before but not my JD. Can anyone tell me if there any pitfalls to watch out for.Thanks.

Just done the same - JD's keys are held in by non conventional means - not the usual spring method but once you work it out it's much the same.

I second the rough end of the eraser to clean the contacts - but, as it took me a while to figure out, always do the same on the contacts on the rubber, not just the ones on the actual keybed. Or maybe I'm just a dumbass.

Good point, I cleaned the contacts on my U20 without cleaning the fubbers and it was ok for a while then started playing up. After cleaning the rubbers as well its great.
There were some tips years ago in one of the keyboard mags about cleaning contacts and it said rub them with paper after cleaning as the contacts don't like it. Don't take any notice; just clean them - I used 'servisol' and q tips.
