Hey everybody! I'm just filling my first modular rack and unfortunately I've already begun 
hitting a small snag. i bought a used 138-b linear mixer a few months ago and up until 
about 2 weeks ago it was working like a champ. It began with the output shorting out where 
I'd have to jiggle the cord to get it working again. I removed the module and inspected the 
back but i didn't see any loose or broken solder points. Just to be safe i tightened the jacks 
mounting nut on the front but it's still been acting shady. Tonight it finally went dead and 
now I'm getting no love! Not looking for a miracle, but maybe just some insight. 

Thanks in advance!!!!!

maybe the jack sockets on your mixer don't make good contact
anymore. tightening the mounting nuts won't help then.
you have to remove the module, plug a cable into the
jack sockets and then push the contacts of the sockets towards
the jack with a small screw driver until they make contact again.
if this doesn't help then maybe an electrical part is broken.
