[sdiy] new CEM3340 in Jupiter 6

[Florian Anwander]

Hello,

This might be interesting for people doing repairs: I replaced 
successfully two CEM3340 in a Jupier-6 with 3340 from the new year 2016 
series. No calibration was required. This is especially interesting, as 
the JP-6 uses selected (= white dotted) 3340's. So these new ones seem 
to conform to Rolands selection criteria.

Also a SH-101 could be revived with an new 3340, but in this case I had 
to adjust the keyboard tracking.
