Update for those inteerested:
Noise has not returned so I am going to assume it was some kind of external interference however i have no idea where it came from or why it lasted 3 days at different locations then disappeared. I still use all the same gear, electronics, and Samsung S20 around the amp with no other issues.
Going on 7 months without any other hiccups and still sounds awesome.
Thanks to all the helped.
