| Try inserting a cord in the effects loop jacs on the back of the amp and possibly the jacks on the front of the amp. These probably need to be replaced. |

| Can you wiggle the plug in the input jack and make the volume change? If so you may have a bad solder connection in that area. |

J,
It appears your amp needs a routine service. There are connectors (Molex) and switched jacks inside this unit that need routine maintenence and attention and I bet that this is your problem. While inside the amp, a tech can measure critical voltages, do a vistual inspection and check for bad (cold or broken) solder joints. I would think that most NV 400 users should consider this servicing about every 5 years or so. This should not constitute a major expense with an ethical and fair tech or shop. My shop charges $40 for such a service for almost any amp, tube or solid state.
