Maybe try a different topology on the Vox model and see if it happens then too. The different topologies have very different frequency responses, so that is what I would lean towards being the issue.

Try the pencil test...With things on the patch where it is making the sound, turn the guitar all the way down and gently tap each tube with a pencil. If you hear the tapping through the speaker, you might have found your culprit...Sometimes some of the plate welds fail or wear in tubes where the plate will physically resonate...good luck.
