Vintage Synth Repair

thanks a lot Brian!
i just bought bicarbonate of soda, i'll have another go at cleansing it soon.


The first time i did it i did use white vinegar as someone adviced me, then
rinsed it with water. 
the battery is still in place though, a 3v lithium one i suppose.
While vinegar is said to be effective against alkaline acid, i don't know
about lithiums,but no damaged should a little vinegar bath have done.

As for the capacitor, if you are curios, its the very first one at the left
of IC16. you can see it here http://www.freewebtown.com/savojr/dk600/pics/battery-removed.jpg.

Or just follow the link to "battery removed" from the main page of that dk600
help site http://beam.to/dk600. It's not an actual photo of my board.
The capacitor was soldered coupled with a resistance leg by leg.So the circuit
is still uninterrupted, there's only the resistance now to provide the conductive
bridge. 
I didn't remove the battery at first since i've yet to identify it looking
for replacement. Also i didn't notice the capacitor broke, so i did turn
the unit on experiencing that freeze after a couple minutes of play.

thanks, Davide
