Manufacturer: National Model #: HRO-7 Electrical condition: I plugged everything together and brought the set up slow with a variac and the set pulled approximately 1 amp and the dial lit up. Unfortunately, I do not know how to work this set as I am a radio guy, not a ham guy. Luckily, for someone smart enough, the original manual comes with the set. The set must be of better quality since it uses qty 12 tubes (13 tubes if you include the power supply). The main center dial spins and turns the variable capacitor. The variable capacitor to dial connection appears to be geared to make the set very sensitive. The inside of the set is very clean. All of the knobs turn and appear to be turning whatever inside. T are several plug in coils I think that they are called that come with the set. They are 3.5 MC to 7.2 MC (the one presently installed in the set); 3.5MC to 7.3 (graph on front); .48MC to .96;.9MC to 2.05; 1.7MC to 4.0; 7.0MC to 14.4; 6.7MC to 14.4; 13.0MC to 30MC. Physical Condition: The main unit is 10-1/2" tall x 20" wide x 11" deep. The main unit has some wear and scratches on the case and some tape residue on the front, probably from something taped on the front. I would consider it in average condition overall. All of the knobs appear to be original and in good condition showing wear from use, and do not have any cracks read more
