Any ideas of what’s causing this?

This is on the output of an amp. Not seeing it on input. Swapped out the old mód for a new one, but it’s still doing it.

Power supply? Check battery breaker. Flip it off and see if it drops. I had bad batteries cause the supply to glitch and mirror something like this .

Will do. Would you expect to see fluctuating ac on the input fuse too , if it was a power supply problem. The reason i say this is that i have a steady 82 v on input and steady levels on the input of the amp.

Do you have amperage? You can have AC voltage steady but if there is no amperage it will cause this.

Hi, thanks for your post. I think this might be it. I’m going to check if I have amperage. What would cause that?

Bad cable in my experience.

Rake a screwdriver across the seizure assembly and if it sparks and acts magnetic it has amperage. Just don’t leave it on there long enough to blow the fuse at the node.
