Vintage Synth Repair

Open it up and have a look. If it has a coin cell holder you can buy one 
anywhere and slip a new one in.

If it's soldered you can either buy a holder and coin cell or buy a coin 
cell with solder tabs. Neither of these options is as easy as the the 
paragraph above, but it's still not hard. They are pretty standard parts as 
electronics goes.

Back up your patches first ;-)
