Hi all,
I've got a Teac VRDS 20 that I use as a transport. A few years ago I disconnected the analog boards as I didn't use them, more juice for the digital part and no interference etc.
Now I reconnected it all, and suddenly I have a weird problem.
There are two relais on the balanced board, and they click like crazy. A few clicks during power-up, when starting a cd, when paused, when skipping to the next track. And no sound whatsoever, just a few thumps. I checked whatever I could (I'm not a digital techie..) but there's nothing broken etc.
I also can't remember hearing those clicks when I first got the player, they're pretty loud.
Now the funny thing is that this does not occur when I use a mains isolation transformer...
Maybe it's too late, and I should sleep on it, but I'm completely lost here: what's the difference???
Does anyone have an idea?
Thanks for thinking with me!

I will do that
But once more: there's no problem when I use an isolation xformer (een scheidingstrafo). That has something to do with grounding too of course
I just don't know enough about these things
The connectors haven't been used in years, so your point of oxidation makes perfect sense..

I don't know the reason for that either because the power transformer inside the Teac already isolates the player from the mains. It's an inherent trait of a transformer with separate primary and secondary windings (I'm assuming the VRDS-20 has such a transformer).
BTW, in your picture I see a black wire with a cable lug just hanging there. Shouldn't that be attached to the frame somewhere?
The connector cleaning didn't do much, so I just let it play for a while to see if a 'warm up' would help. And it stopped the clicking! But still no sound
As I had run out of options for the analog pcb I went back to the servo board. Although it's a major PITA to get it out
Previously I had altered the S/PDIF out, so I checked if I didn't miss anything when returning it to it's original state. Everything was fine, maybe some small particles on the pcb. I brushed it off and hey presto: it worked again!!
I've spent countless hours on the darn thing, so imagine my happy dance
End of this story, thanks for the help everyone!
