Vintage Synth Repair

FWIW, I replaced the broken J-wires in the Prophet 5 keyboard with
0.38mm guitar wire(D'Addario PL015, to be specific).  Silver solder
was used.  Seems strong enough.

A white-face Odyssey came in last week for a keyboard overhaul.  The
keyboard module was made by the same outfit as the Prophet's (Allen &
Heath), but seven years earlier.  It is amazing how much better
quality the earlier design is!  I don't know if Allen & Heath had
cheaped out over the years, or if SCI simply wouldn't pay for better
quality -- but I'd sure be interested.  If there is a link to a
history of Allen & Heath, and the various versions of their keyboard
modules, it would make interesting reading.  The extant Allen & Heath
is a British company that makes mixers, http://www.allen-heath.com/. 
Their website gives no corporate history.  Did the old keyboard
modules come out of Britain, or is this a different company?
