emulatorII-list

Hi ! 
i've just opened my emulator II, reading what you said about the ssm2045 chips. .... What if on the main output, the sound becomes wierd, after 10 minutes of perfect use ? i plugged the jack into each voice output, and the keys were the sound came from ( aleatoire ) produced the same wierd sound as on the main output. but only after about ten minutes of use, i can't understand what's going on ....
what else could that be ? should i replace each chip of each board ???
thanks a lot everyone if you have any clue, and some time to read this sos message.

best,
Adrien
