I thought my right deck was fucked / had a loose cable / connection as it wouldn’t play through the right monitor. I was about to get the Deck Dr out when I thought I’d have one more go at a diagnosis. I took it down and gave the cable a wiggle and plugged it all back in and it worked again. Before dropping out again.
When I had my headphones on, I noticed the same thing was happening with the right can. Fuck knows why but at that moment I remembered reading a thread on the old GU board about djs taking off the stylus and dabbing the connectors on their tongues when there were bad connections. I gave it a go and fuck my old boots, it’s fixed.
