Discussion about the Korg PolySix synthesizer

Hey everyone, well here's the info if anyone is interested.
I work at a music store, we have a repair department, and i
ended up finding a pretty beat up Polysix.. :|

In anycase, keyboard contacts were screwed and irrepairable,
and my keyboard tech rangled some from someone...
I'm trying to go through and fix it myself.  The only problem is,
of course, battery leakage.  I have taken out the battery, and
it seemed that the 74LS08 AND gate beside as infected as well, so 
that has been removed as well.  I am doing a hard wire of all the 
traces that are bad... (about 14).
Before i had taken the battery out, i had plugged it in, and the VCO 
was non existant.  My question is, when i fix the 74LS08 and 
retrofit a new battery, will my VCO return?

The wierd thing is, even without the VCO controls active, the thing 
sounds amazing, already in love with the filter and partially in 
love with the reso.  Just hope it sounds even better if the VCO 
returns.

Thanks for the help.
Jay

*sniff*... fixed the traces, ran without the battery, i couldn't 
find any reason why not to within the service schematics, besides i 
hardly ever save a patch, like the spontenaity of things.  Alas she 
didn't even chirp, didn't smoke, nothing...  it's now 3:48am... see 
what the afternoon brings when i get up?... any suggestions anyone?

She sounded like a good board when she was sick.  She's just dead 
now..
:~ (

keep looking at the traces...  you'll find more bad ones.  get a magnifying glass... you'll find more.  check pin to pin with a continuity tester... you'll find more.  then you can turn it on, and it will be beautiful.
