This version of the 1625 receiver also tunes the broadcast band and also operates with a single wall wart power converter. Nothing going to bite you here!
It is rather difficult to see from this picture but the supporting tube for the coil housing is off-set from the center...it is actually mounted on the back side of the circle. You can just make it out with the wires trickling down the inside of the tube. If you look closely at the coil you will notice that the outside layer appears to be a different color than those wires underneath...kind of a purple-ish grey. This is a "tickler" coil which is completely separate from the "main" coil. Rather than having a "primary" coil, this set uses a variable trimmer capacitor mounted under the acrylic base.
This radio is much more compact than it's cousin shown further down this page but the performance is anything BUT compact. It BOOMS & ZOOMS with the big boys. The base is my favorite of all materials....Padauk wood from West Africa! Dave tells me that I spell the word differently every time I write it. Could be but they are all used in the wood world. This one, however, is the official spelling.....mine at least.
That big brass knob is 1" in diameter and is solid brass and controls the regeneration of the set (the squeal). The solid Padauk knob and serves as the tuning control. Brass binding posts for antenna and ground connections are on either side of the tube.
This radio may be compact but it weighs a ton with all those big fat brass parts on it. Please e-mail me for price and availability.
