Help me diagnose my Mini Rectifier loop issue

[waygorked]

I'm running a stereo rig with 2 Mesas, a TA30 and a MiniRec. My pedal board is a bunch of fuzz, boost, and OD pedals into a Diamond Halo Chorus, which splits stereo into the amp inputs. From there, I run the effect sends from both amps into a Strymon Mobius, Timeline, and Big Sky, then stereo out from there into the effect returns on both amps.

This rig sounded amazing until last week. I tore my pedal board apart and replaced a bunch of cables as I reconfigured everything. Now I have a crazy loop issue I don't understand.

The TA30 still sounds like it should. But the MiniRec seems to be putting out a 100% wet signal. When I switch off the MiniRec's loop, I get no sound from that amp with no impact on the TA30. When I switch off the TA30's loop, it kills the sound to the MiniRec as well.

Does that sound like something wrong with the MiniRec's loop? Bad tube in the loop? Bad cable somewhere? Any other ideas? I read on another thread that the loop return level on the MiniRec may be controlled by the master volume? Could that be the issue? And if so, does the V25 work the same way? If not, it may be time to swap amps...

Have you tried a guitar straight in without anything in the loop?

In particular, the Mini's input cable needs to be tested/checked. If the amp is 100% wet and is silent when the loop is off, it's possible that nothing is coming in the front. That's the same reason killing the TA kills the Mini. The Mini effects Return is the only place it has signal coming in and that is only what is being produced by the signal originating at the input of the TA.

It looks like the problem is specific to the TA30. I'll explain in a thread in the Atlantic forum.
