Subject: SDSV Trig Voltage Decrease

From: lackan110f@...

Hi everybody!


I am new to this group, and the reason I am here is that I recently bought a SDSV-brain with 5 modules. I had a couple of questions and electronic obsession-Jesper thought it might be a good idea to pop them up here. 


First:

I am triggering the SDSV with a +10V trig signal. But the DSDV prefers +15V. Since the trig inputs are wired with a 100kOhm to ground, I tought decreasing this resistor might lower the SDSV's need for 15V to 10V. 


Has anybody done this? What is a good value to aim for?


Second; 

I think that the mixer section might be faulty in some way since slot 4 triggers slot 6 as well. First I thought it was a mod of some sort but it isn't. And the sensitivity pots don't seem to do much either. 


But my question is - how does one removing the mixer section? It is multi-pin soldered to the back PCB and the trafo sits on the right wall? Its like a chinese puzzle… :-)


Thanks for reading this far, best regards Peter in Stockholm
