My PS-1 is from 2015 and I’ve barely used it the last couple of years. Today, I fired it up because I needed a 4 Ohm reactive load but I soon noticed that the amp in, speaker out and line out jacks are all loose and lead to intermittent connections, i.e. wiggling the cable leads to vastly different volumes, sometimes no volume at all (which sucks for the amp in jack as the amplifier needs to see a constant load) and it’s tough to find the sweet spot where the volume stays at a constantly high level.
Is there anything I can do to fix this problem? Tightening the external screws of the jacks maybe?
I really hope that I don’t have to get all of them replaced by a tech…
