Description: James Millen 90800 50 watt exciter.It is a Tri-Tet oscillator with harmonic output using a 6L6 and 807 tubes (included) as described in QST November 1940 and Electric Radio May 95. The 90800 was available just after WWII ended. The price was about $40 without tubes or coils. The oscillator is a metal 6L6 tube that can be either crystal controlled or can be operated with a separate VFO. The PA is an 807. Plug-in coils are used for the oscillator grid, oscillator to PA coupling and PA output. Coils were available from Millen. A separate power supply was required and, although Millen offered one, most hams built their own. Most of Millen's products for hams were component units that would be used to build-upon and then, with a few other components and some homebrewing, a complete transmitter could result.
