• Citizens  Band  40 CH  Tube Transceiver PLL Controlled.
  
  This is a unique example of a Tube-Drive Radio made in the mid to early 1970's with Phase-Locked-Loop Technology.  It is used for a 40 channel CB  in the frequency range of 26.965 to 27.405 MHz. The circuitry is common for many Tube CB transceivers made in this era (like a Japanese Tenko), but user friendly and with extreme stability.
  
  Made in Japan - USA project.
