SCI six trak problem

2006-05-21 by analogback

Im kicking myself about destroying a mint sixtrak that I just bought..
it seems in the process of plugging it in to a 240v - 110v stepdown
transformer the polarity was reversed via an US-AUSTRALIA adapter.
everything on the synth appears to be functioning except now there are
no oscillator sounds only filter resonance. Does this sound like the
CEM 3394 chips are dead? 
Regards, Gab
