Peavey VIP 2 buzzing/crackling

Hi...My Peavey Vypyr VIP 2 started buzzing and crackling a gig tast week. It reminded me of what it sounds like when a speaker is about to fail. When I got it home I swapped out speaker but the problem remained. Tried different guitars...same thing. After I turn on the amp it takes about fifteen minutes of warming up/playing before I can induce it to start buzzing. It is induced most easily when thumping on Bb or B note on the E string. Near the end of the clip I play a C note and the buzzing/crackling goes away. I have tried to attach a 1 min. 15 sec. sound clip:

See if the input jack has any effect on the noise (wiggling the male 1/4 jack).

Thanks. I should have added that I've tried that along with trying different guitar cords.

Here is a link to the schematics you will have to direct us to which is the version you have.
To me it sounds like some freeze spray may be needed to suss out the issue.

Is there a line out or FX loop? on this model?

Thanks for the link. There is a 1/8in. headphone jack on the front. There isn't an effect loop or pre out, pwr in.

If using the headphones do you still hear the buzzing/crackling?

And when it does it, ball up your fist and whack the op of the amp.  Does that make it stop or pause the humming?

That's the first thing I tried at the gig when it started...no effect.
And, no difference when listening through headphones.

It could be as simple as a loose panel or screw, even speaker baffle it's been noted here;

Then again it could be the electronics and these are all digital so quite complex.
Some say to reboot the whole thing to reset all the digital wizz stuff.
