I solved it ... nothing spooky with this problem. My "known good" Cross-Check SSM is now a "known bad" SSM !

After the replacement of the socket nothing else could be the cause of this problem, so I repeat all my steps during repair and found that my known good SSM shows the same behaviour as the one in the defective voice. It must be died really quiet ... without any notice from me Shocked)

Now all voices are working. I replaced all SSM-2044 Filter against SSI-2144 with little adapter boards. They sound really good in this Emulator 1 and first of all they all sound exactly equal.

For everyone who is interrested : The Emulator 1 has only 8 different VCF-Settings available corresponding to the 3 Bits from IC33 Pin 6,5, and 2. Depending on their switch-state (0 or 5V) they create the control voltage at pin 13 of the SSM Filter through the following passive resistor network. For the whole filter range from completly close to completely open you can measure a voltage from round about -35mV to +35mV at the Control Pin of the SSM. At my opinion these 8 steps are absolutely enough for a manual setting per Slider.

First thought about this was ... only eight steps ? Did they realize a form of PWM at these pins to get a higher resolution ? Look at the 100nF capacitor at the control pin ... it might be possible to realize it with todays computing power but not with these ancient Z-80.

As I read there was a hardware option available for expanding the Emulator 1 possibilities regarding Filter Cutoff ADSR and Q-Control. Does anyone has information about it ?   

Keep on repairing and sharing your results ...

Update : Added a picture of the SSI-2144 Filter with adapter board.

Hi, I changed the psu from 5volt 15 amp, with a 20 amp 12volt 6,5 amp in a single container, to reduce internal heat in this way I can decrease the speed of fans, reducing the voltage from 12 volts to 9.5 in this way the noise of the fans is much improved

psu 1: 5volt 20 amp
           12volt 6,5 amp

psu 2: +15 -15  4amp

Is this power supply upgrade different than the pervious power supply upgrade posted in June 2017? What is the items that you used with this displacement second power supply?

Okay - good to know.

I bought mine ten years ago for 500 € each. Wow.
