Hello,

I power up my Doepfer G6 with "standard" power supply (0.6 A), than it works
for a few minutes, than it dies. Sometimes gentle tap will bring it back to
life, sometimes it requires firm shake.

Is there any place on power supply that I could check myself for loose cable
(without killing myself), before taking it to my Doepfer distributor

Is there any chance that third-party module I had at the time, and that was
failing on and off by itself (loose connection on the module itself) could
affect the power supply Sorry if this question is stupid, I am really
clueless when it comes to electronics.

Regards,

Zoran
