Vintage Synth Repair

OK, I have my Odyssey apart for cleaning and took the opportunity to
examine the back panel connections to the power supply board. There
are stake-on connectors and even a sticker on the rear panel that
indicates where the wire should be pushed on for 110 or 240 VAC
operation. No tools required. (Except a Philips head screwdriver to
remove the six side screws and eight bottom ones.) This information
applies to the yellow on black Mark II model (2813), but may be the
same for white and orange units, too.

leads of the transformer for 110VAC operation. For 220VAC operation
the black and blue leads should be used. (This may be easy, if you
find a jumper between the blue and white lead. Simply remove it.) If
you don't feel comfortable making the change, any electronics repair
place can easily do it if you give them the unit and the schematic.
It's less than a five-minute job.

circuit diagram all you need to do is swap the tapping point from 115V
to 230V, note that the whole of Europe now operates on 230V although
if you measure the voltage you will probably find that it is actually
220V in Denmark, while here in the UK it is 240V as
measured!<?/bigger><?/fontfamily>
