Taken from the popular comedy sit-com this radio displays the theme perfectly, that is when the tube is lit. And that tube is the rare, beautiful and entertaining EM83 magic eye! It dances, it prances and reveals modulation on one side and signal strength on the other. Never a dull or still moment w ith that thing. And this happens to be the best performing set of its kind that I have built to date.
The circuit is powered by a dual secondary transformer that provides for the 5 volt filament and 160 volts for the plate. Both are converted to dc and the filament is refined with additional voltage limiters. The tank consists of a coil I wound on a toroid form using 175/46 litz wire to 180uH and a standard 365 variable capacitor.
The cabinet was constructed of black walnut with the front panel being steamed, bent, dried and attached to its framework and the top panel being of the same stuff. The tube shroud and the speaker grill were both made of maple to add a little contrast to the rest of the set. A special cherry red stain was applied and then finished with a very flat nitro cellulose lacquer that I mix. The result is a nice soft balanced look that is just perfect.
The dial face is a Howard Radio specimen from 1937 and is housed under a convex glass crystal. The dial pointer and knobs were constructed of solid brass. The dial is activated by right angled gears mounted inside the body which can be a rather daunting task to assemble. But it works really well and provides a point of difference for this radio.
