SOS, please note that your PP 2000 does not isolate one component from another within the reconstituted 60 Hz circuit. It only isolates those components from the noisy and variable wall voltage. Since you think you must isolate your TT and phono stage from the wall mess, and I think you should also, do yourself a favor and purchase an APC 600, one of the light tan models, not the noisy, smelly onyx models. Do not run it from the PP 2000 , run it from the wall. The PP 2000 will then shelter your other components from this newest insult also. I will be interested to know if this new APC also provides hum. If it does you must isolate the phono stage from the motor of the TT with yet another APC unit, or just plug your TT into the wall. If you also have a computer controlled music server for digital content the computer power supply should not be in the PP2000 isolated circuit, these are very dirty power supplies and will defeat what you are attempting to accomplish.
