Doepfer

Hi all,
I've finally entered the world of modulars. I got a good Doepfer setup
from ebay last week and it's been great fun so far :-)

I don't know how the unit has been stored - or if this is just a
problem with 3.5mm jacks - but I have a few intermittent connections
and so I'd like to give all (!) the sockets a good clean. Anyone got a
favoured method? Or is just a case of spraying contact cleaner around
the place? Is there a burnishing tool available for minijacks?

Also, I don't know if the supplied patch cables are original Doepfer
or not but they seem a bit feeble. Can anyone suggest a source of high
quality patch leads or am I better off making my own?

thanks!
