Used Octatrack mk2, Noise on Recorder Tracks?

Hi, I just picked up a used Octatrack mk2 in seemingly good condition. I noticed that the channel A/C lights on the input tracks were wavering green even though they weren’t plugged in. Monitoring them, yeah they’re pretty noisy for no reason with the noise gate at -inf. I find that to get rid of this I have to bring it up to about -50dB or so.

When I plug in a stereo connection it sounds fine, which is good, no noise. When I plug a mono connection into A, no noise. When I plug a mono connection into B, I get noise on A unless the noise gate is on.

I get the feeling having the noise gate up to that level would be fine for most cases, so I’m not that concerned, but any idea if it could get worse?
