| Try reshaping the female ends on the molex connector. If they do not make good contact, they will cause a hum. Use a small screw driver to push the two tabs together |

Thank you. I doubt finding a new end. I think they quit making the 4 hole.
I will try this. |

| You may just have to turn it off or disconnect it and go to an outboard reverb. I love my Wet Reverb. Much more natural sounding than any amp reverb I have ever heard. You may have a blessing in disguise. |

Last night the reverb didn't work during soundcheck on my trusty NV400 workhorse. It's happened a few times before over the decades. I reached in and wiggled the Molex connector, pulling it off and pushing it back on. Back in business.
It's always the Molex connector. |

No, it isn't alwaysthe Molex connector. I had a high pitched squeal that got louder as I turned up the reverb. I cleaned and tightened the molex conectors on the cable and chassis. Somebody here loaned me a tank and cable. That made no difference. So I just pulled the tank out of my amp and use a reverb pedal in my effects loop. Oh, and I can still here the squeal a little bit when I turn the reverb knob up.
But, most of the time it is that stupid Molex connector.

| If you are certain that it is the Molex connector, then remove the connector and hardwire it. |

Exactly. I do that and hardwire the speaker Molex. You can unplug the reverb can and detach the speaker wires at the speaker for service. I've done several that way. Jim Loessberg was having issues with all three of his 400's. I did this to all of them and he's been trouble free.

One possible fix for the dreaded MOLEX intermittents is replacing the standard pins with GOLD pins:
Mouser P/Ns 02-06-5102, 02-606102; 02-06-7104, 02-06-8104.

| Also you might want to check your jacks on the front and you plugs. Take a Q-tip and dip it in some rubbing alcohol and then swab it in the jacks on the front and back of the amp. Also take some pour some alcohol on a clean rag and wipe your ends to your plugs. See if that will also help. |
