Any ideas anyone? I have a feeling channel 3 has a bad input.
Maybe CH3 has a fault which is blocking the delay system from working on any channel.
Are they modular at all? can you pull out the channel 3 pcb ?
Unfortunately this is the board here. I would have to think that everything having to do with the channels would be located in those silver boxes.
The only issue I'm having is with Calibrating the delay trigger and on channel 3 it seems as if the input has been zapped..
