| I have Nashville head in separate cabinet. Not tall. How can you insulate reverb when close to transformer? Thanks, Ken |

| Nothing beats space, but one easy thing to do is to orient the tank so the input is farther away from the transformer. Another thing that might help some is to put a piece of steel sheet between the transformer and the tank. (A piece of annealed Mu metal would be far more effective, but that might cost you $40-$50.) |

| Thanks. Should help. I meant isolate instead of insulate. |

| Try the tank in different positions and listen to see if one place is the quietest . You could locate the tank in the speaker cabinet though you would need a longer reverb cable and a provision to connect and disconnect easily . I have done this using a 3 pin xlr microphone plug . |

Hi Ken,
I was thinking about this too, if I came across that problem with separating amp & speaker. Maybe a metal shield around the transformer or between the transformer and the reverb tank, may help, but the metal shield HAS to be a magnetic metal to help guide the magnetic field away from the tank...... That would be a cheap method to try.

FWIW, I've built a few NV400 head cabinets. What I have found is before you bolt down the rev pan, turn the reverb control full clockwise and carefully position the tank to where it has the least hum. I've nearly always been able to mitigate the hum, if not completely, to an acceptable level to where it isn't noticeable when playing.
Be sure it is oriented the same way as in the original amp cabinet. If it's reversed end for end it will hum like all get out. |
