In for a problem in heater wiring, corrected and working fine on the bench. Reassemble in cab and no output now. I'm loathe to have to now take the main board apart unnecessarily if I'm doing somrthing silly as there are a number of awkward quirks about this model. Feed signal in the "Return" and it outputs to the speaker. Normal signal to the front input and output at "Send". There is 0R across all 4 un-inserted "return" socket contacts as per schematic. ch select switches and status LEDs work but pressing the muting switch does not mean the 3 LEDs come on together now as a reminder indicator (this function not mentioned in the user handbook). I've removed the digital board and nothing seems amiss with that (secret lock within the XLR). Relay click at initialisation at power up.
