Patches and discussion for Ensoniq VFX family

...sorry to add yet another post on this problem, but I could use 
some advice from VFX veterans. I recently picked up a VFX with the 
calibration error thinking I could fix it, but it's a bit more tricky 
than I thought.

It looks as though the hard-wired repair has been attempted in the 
past, but not very well. It seemed to me that the original connector 
looked as if it had 12 wires going across, but only 11 new 
connections had been made. It looked as if only a single join had 
been made across the top two; as if the top connection points on each 
side were linked, if you see what I mean. A large blob of solder on 
each side joined them together.

I cleaned the solder off to investigate, but it appeared to me that 
these points were indeed originally joined on the circuit board, so I 
thought maybe they knew what they were doing after all. 

But looking at the help sheet in the Files sections, it seems that 
you do indeed have to make 12 connections. It's not very clear from 
the picture exactly where they are though. Can someone confirm that 
there are twelve individual separate points on each side that have to 
be bridged...? Or is there a single point on one side going to two 
points on the other side at the top of the board, or what...? 

(Apologies if this is unclear - I'm a soldering newbie so I don't 
know the technical terms.)

Thanks!
