Boredom got the best of me: AA5 hum and loop antenna

There are no terminals, but then, the schematic I linked may not be the exact one. I searched on line for it the exact model and someone on a different public forum said this the one I linked was the same chassis, but perhaps not.

The tube lineup is the same, the hard parts layout is the same, the tuner and dial cord stringing is the same, and all the resistors and caps are the same, so I assumed it was the same chassis with a different cabinet. The schematic even shows the loop and the third unattached segment.

The antenna loop board makes up the backboard, and there are no external connections to the radio of any kind.

I'll take a pic and post it tomorrow. Thanks.
