Super Hot-rodded 37-620 Schematic
#10

It's a 37-670 for sure; the label says so and there's no low band. When I first saw it I too thought it was a 37-2670 but checking under the hood and looking at the dial proved differently. It's getting a slow but precision chassis restoration: spaghetti on all component leads, wrapped joints, Alpha solder, and acetone-cleaned joints.
