Hi Group,

My Roland MKS-70 (SUPER JX) 's power supply is failing . After two  
seconds it shuts off. I am suspecting capacitors on the power supply  
board. Can anybody tell me an easy way to get to it. Before I make  
some stupid mistakes?
It looks like I have to loosen the VOICE boards that are on hinges ,  
right ?
I googled the MKS series and they seem to be a bit flaky in age.
Also maybe one of you knows already the problem. What's the deal with  
the sensing in the circuit ?

Any help greatly appreciated
