Thanks Robin. Yeah, I was not expecting that to be the sweet spot, that’s for sure. But it isn’t even a close call. The hum is clearly quieter in that orientation (it’s zero there). I was wondering whether I was getting too close to the input, and of course the headphones don’t help with that. From looking at your photos and Andy’s, it looks like the midpoint of the chassis, or maybe slightly closer to the PT, is ideal?
I hear you about perfecting the position after I fire up the Amp. I’ll try to do that. But I guess I need an approximate location/orientation to start. Thanks!
