Redco Bantam Ground/Cold issue
 
Hello

I have a Redco Bantam patch, with DB25.
I seem to have a issue with one channel where Ground and Cold are touching each other, I have tested the cables and what not and come to the conclusion that it is something wrong inside of the patchbay! what can this be? send help.
The connections are half normalized and vertically stripped ground.

Thanks for any help!

With all external cables disconnected, use an ohm meter to measure resistance between ground and cold on your problem channel. If your meter indicates a short, or anything other than a fully "open" condition, do a careful visual inspection of both the DB25 and the TT jack. It might be a solder blob, mashed wire, a small part that fell into the bay, reversed wires, bent contact, etc.

If the are nothing connected at the back, the db25 is out. inserting a TT jack and meassuring that the ground the cold are touching, the same TT jack works on other channels.

Is there a way to get inside the patch to see if something is wrong there?
so It could be on the db 25 connector as well, one of the pins on the bay is touch, or the tt connector?

The fault could be on the TT side or the DB25 side. I don't know what's involved in getting access to those connections. You'll just have to figure out how to open it up so that you can do a visual inspection. Start with the side that is easier to access.
