Either the amps are sensitive to RF signals or the cords ( power OR speaker ) are acting as antennas. Sometimes, simply moving the cords into a different pattern can cure the problem. Sometimes altering their length can cure the problem.
I would start off by trying to wind up any excess power cord into a small coil as tightly as possible near the amp. This will create a choke and may get rid of or minimize the problem. If that doesn't work, you can try attaching a ferrite clamp to the power cord very near the amp. You might also try shielding the amp ( large metal pot, turkey pan, etc... ) to see if the tubes or circuitry are picking up the signal if it doesn't already have a "cage" covering the tubes. While i would think that your speaker cables would be okay due to their geometry, try substituting some different cables to see if that helps..
Depending on the situation, it can be a tough one to solve. Take your time and do it step by step. Sean
