Just fire it up and test it out.

Ok, fired up, voltages all within range. Only problem seems to be a very low hum in both channels. It goes away when the volume is turned all the way down on my amp. Any suggestions?

If you don't have your turntable hooked up, you could get some hum from the open input.  Otherwise you may need to experiment a little bit with where the Eros sits to minimize magnetic hum pickup.  I haven't experienced this issue with the Sowter step-up transformers, but definitely with some others in the past.
