While I had everything set up with perfect 30 degree angles I went ahead and created a new six sided radio with new twists for a short wave set. Dave Schmarder gave me considerable guidance on this new schematic which rendered it to be the best performing shortwave radio I have built to date. It tunes from about 8.9 to 18.7mhz and is very active in day time hours. There is some activity at night but I hit the rack so early these days I cannot say just how active it is.
Obviously the radio utilizes the old 1625 tube and the coil is air-dux and is nicely displayed behind the tube. It features an antenna tuning, a fine tuning and a main tuning variable capacitor. The main tuning variable capacitor along with the fine tuning capacitor had a combined capacitance measure that was reduced via a fixed capacitor down to 110pF. Other components include a regeneration and an amp control knob that balance the layout. It also incorporates a beefier speaker that handles the output from the amp very well indeed.
The six panels of the cabinet were constructed of cabinet grade maple laminate while the two top panels were finished with select red wood burl which was also used on the skirt of the main tuning knob out front. The beauty of this material is just incredible and adds a whole new dimension for the radio. Every thing was stained and shaded red with lacquer dyes from Stewart McDonald Stringed Instrument Supply and then finished with satin nitro cellulose lacquer. By all reckonings this is a very superior unit.
