What is the lowest voltage acceptable ?


I live in an apartment building and the AC voltage is usually 121 VAC. Lately with the hot weather Con Edison has had problems in Northern Queens , New York. My voltage has been lower and fluctuating between 119 and as low as 109. Right now it’s 115. What is the lowest to safely power my system?

The older PS Audio Power Plant Premier works well with my 60 watt/ch tube integrated amp. It worked well with my previous SS 80 watt/ch amp as well. Dynamics is not compromised. Everything is significantly better than without it or with older Furman voltage stabilizer.

I would not, however, recommend this particular model. There were many reported reliability issues. I got lucky, my unit has been trouble free since new, that's more than a decade. And PS Audio stopped repairing this model, I think.
