Seventh Circle Audio

I just finished installing the power switch, power light, and grounding wire on my pre-built PS02, got it into the rackmount case, then plugged it in, turned it on and measured my voltages.

I read:
Pin 1: +27.062
Pin 2: 0
Pin 3: -27.582
Pin 4: 0
Pin 5: 48.349

The instructions say if you are off by more than .2 volts then there is a problem. So, pin 1, 2, and 4 are fine, but technically pin 3 and 5 are slightly outside the margin of error. All measured voltages stayed consistent to within about .005 volts over a period of about 5 minutes. Is this a problem, or are these voltages acceptable?

You're fine. The worst one is only off by 2%, and all the preamp modules have local regulation. on the +/- 27v lines. The +48 is within spec for phantom power.
