For clarities sake - sequence of events:
1. the power company repaired the neutral.
2. Installed 20A dedicated line.
3. Returned repaired 975 to HT center stage!
4. 5 days later 975 failed... ...3rd time! 😿 frown

Renov8tor: that Tripp lite is an awesome unit. It provides 5-10 times the capacity for my needs. Something $maller please? Your suggestion would never pass the WAF muster.
