Express 5:25 1x10 pops and crackles

Just picked up a used Express 5:25 that sounds very nice --

There are tow elusive issues:

1) Regardless of volume settings, footswitch and effects loop use [even with no tubes at all], there are cracks and pops in the background

2) When I turn off the amp too quickly after turning the standby off. there is a medium stutter sound that gets generated whether the Flashback is engaged or not

... If I remove the loop [Suhr Mini Mix II] -- there is only the loud pop.

3) I put the Flashback on his delay etc and it does not affect the pops ... ie, the cause must be at or after the effects return

Ideas to start?

Thank you:)

I'd start by cleaning the effects loop jacks.
