Dear User Group,

I'm in need of general advice about my PolySix, trying to determine if I
should attempt to get repaired, or just enjoy good memories. Here's my
story:

I purchase my PolySix new in about 1981 or 1982 and used regularly until
about 1985. Since then the unit has been packed away. I began reading about
the battery problems and opened the unit to take a look. I found that the
battery had been moved away from its original position and placed off to the
side, away from any circuit board. I don't remember having this done, but I
guess I did. The battery is original equipment and has coroded, but appears
to have caused no damage due to its placement.

The synth will make some sounds, but almost none of the knobs and swithces
work properly. The "B From Tape" bank button and #2 program LEDs remain lit
at all times, even when other buttons are pressed. The unit will not accept
or restore programs from cassett tape and some of the keys do not work.

I have no tech experience and would have to rely on a professional to get
repaired. I live in the Atlanta, GA area. Wizard Electronics has been around
since my playing days and I would probably take to them. 

Other than neglect over the last 25 years, I took good care of the PolySix
and looks almost brand new. Any general advice would be appreciated. If it
were yours, would you pursue getting repaired or has its time most likely
passed. What might be the problem and would it be expensive to fix. I know
that this would be a guess having not seen the unit.

Many Thanks

Jeff
