Vintage Synth Repair

Hi, thank you for the quick answers...  

I did not solder the battery out yet. I measured with the units power
turned off. As far as the unit is working well so far, I think, the
battery should not be the problem. 
The Source is not loosing his patches or something else..

The LFO LED is blinking, and of course you can change the speed of the
 LFO. No problem there as far as I can see. 

As far as all IC´s are socketed, this could be a good hint. 
Where is the RAM located? which board? I think it has to be the
digital board, right? Makes sense to me that the defect could be on
this board. Is this the one on the left side inside the unit?

Cheers
