Mellotronists

I just bought a Hohner Cembalet I on eBay.  You can see it 
in "completed items" still I imagine.  This seems like an incredibly 
rare model - the Cembalet is the precursor to the Pianet but most 
references on the Net are to the "N" model, I don't see anything that 
looks like the one I bought.  In fact the only reference to 
a "Cembalet I" on the whole internet has a question mark after it!

Further, there are a number of schematics online for Pianets and 
Clavinets but none that show a tube preamp as this one has.  It must 
be VERY early production.  Seems to have lived the bulk of its life as 
it was originally intended - as a home instrument in Germany.  
Unfortunately, it sustained some shipping damage which has me pretty 
heavily bummed out.  Any electric piano experts in Chicago?  Beyond 
that question... I don't know if this is remotely interesting to 
anyone on this list, but just who else do you tell when you buy 
something like this - the guys in your Fantasy Football league? (no, I 
don't play fantasy football - just using that as an example).
