Fender Amp Static

I have a '73 fender vibro-champ that started making static like noises at random. It doesn't matter if there is anything plugged in to the amp and the volume of the static doesn't change with the volume control. I've replaced most of the resistors already on the main chassis of the amp. I have also noticed that the #2 input jack isn't working any more and there is a resistor there. Could the #2 input jack and its resistor possibly cause this issue?

I don't know much about amps but you might check your chord and the outlet it's plugged into. Other than that I've got nothing.

Like I said, it does it without even having a cord plugged in.

yes, those input jacks are prone to causing crackling noises.
Try some De-Oxit' contact cleaner ( I would take the jacks out first, that cleaner is messy and you do not want to get it on the wiring ...also like any vintage amp, the power supply and all electrolytic caps should be checked and probably replaced ..
ans actually first thing: check & swap preamp tubes ..they can cause noise when they are going bad.

I've already swapped preamp tubes from another working amp and the static noises are still there, they very random. The amp sounds clean as can be one minute and then the static noises hits for a few seconds and is gone. it comes and goes every 15 seconds or so.

Should have explained myself better, I meant the power chord to the wall, not the guitar chord. Good luck with it though.
