I've had my A-100 synth (started with basic system mini) since new only 5 months ago....

Yesterday after switch on, one of my A-110 osc sounded like it had random voltages going on inside
It sounded really sick in the guts

no patch leads apart from the osc output so was definately something not right....

my other A-110 was and is fine.

after fraking out for a coupla minutes, i plugged a lead into CV1, and everything's fine. Take the lead out and everything is fine.

The same thing happened again today about 1-2 hours after start up.

the osc goes all sick sounding ..... i plug an unconnected lead into CV1 breifly and everything is fine for the rest of the day (another 8 hours)

what gives

any help or experience

thanks
