Power Amp transformer hum - intermittent and increases and decreases in a few seconds

Checking to see if anyone can tell me if blue circle power pillow or emotive cmx-2 can solve my hum issue. Or is there something else I should be liking at?

Mechanical hum is not always the result of DC offset. I have some DC offset on my mains and even two DC blockers in series couldn’t eliminate an obnoxious hum in one of my amps.

Anyhow, I own the CMX-2 but found the Audio By Van Alstine Humdinger works far better. I had a bucking transformer that still hummed loud when plugged into the CMX, but it ceased completely with the Humdinger.
