Help and Embarrassment or Riches to Rags in seconds

Head low, I tell this tale.
Premier 350 amp plugged into a Furman IT Ref power bank. I had my 16LS2 plugged into same bank. Revel Performa3 F208's bi-wired to 350. I had swapped out my Premier 17LS because I had been wondering if it sounded better than my 16LS2 and plus wanted to swap the P16's tubes, so why not. I put the Premier 17 on a different outlet, a Panamax M5400 which housed my cable TV wireless, switch, etc and because it was easier routing that to the Panamax. The P17 sounded great. Later in the day, the cable box was giving trouble. I had to swap out some wires and one thing to another. The amp was on, the music was playing. In a moment I'd forgotten I put the Premier 17 on the Panamax along with the cable stuff. In a quick moment I had all the cable stuff off and at last minute decide to move the Panamax to a new outlet just below to make room on top of the 2 gang 110 outlet. My helper pulled the plug, the Premier 17 went hard OFF. A loud pop through the Premier 350 to the Revel speakers. In a panic the plug went back in; a split second and the second thunderous pop.
The right speaker of the Revel is toast; the crackling of the 8" speaker. Now what to check.
I'm more worried of the Premier 350; want to know what you think I need to check, all visible fuses are accounted for and ok. There are 8 fuses in the Premier 350 power amplifiers. One is the ac power line (mains) fuse. It is located in a fuse holder on the back
of the amplifier, near the IEC main power cord receptacle. There are four fuses for the main DC power supplies. These are located on the
back of the chassis in fuse holders above and to the right of the power cord, labeled B+ and B-. On the bottom of the main pc board, there are
two fuses to protect the high-voltage power supplies. Finally, inside the amplifier on the right side near the ac power receptacle, there is a fuse
to protect the turn-on circuit. All fuses are accounted for but did not see the Turn on circuit. It turns on fine.
What volt reading should I look for from speaker out R/L? Ideas and thoughts.
