The inside of classic radios holds wonders that the sterile chips and SMD components of today’s circuits can’t hold a candle to. Chunky resistors and capacitors, vacuum tubes with cathodes aglow, and ...
A total of 15 are available, three with voltage ratings of 15kV and one each of 8 and 10 kV ratings. The ranges available are 5-30, 8-50, 16-80 pF for the 15kV rated units and 5.5-206 for the 8 and 10 ...
Marked: "Dayton Fan & Motor Co. / Dayton, Ohio, U.S.A. / Day-Fan". A Variable capacitor with six fixed plates and six movable plates. Arrangement of plates permits interleaving of sets of three each, ...
Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...
