ADMIRAL COLOR TV - CHASSIS K10 SCHEMATIC DIAGRAM (VINTAGE TV) -1974 MODEL – HYBRID CHASSIS (USING TRANSISTORS AND VACUUM TUBES)

  (Hybrid) color TV - Admiral Chassis K10 - Vintage TV - 1974.  Spare component availability will be rare.  Just compare this with modern TV circuits, and feel how much the field of electronics have developed.  There was no integrated circuit (ICs) at that time.

 The circuit consists of both tubes and transistors (Hybrid type). Tubes are used at its horizontal output and video output stage circuit. Most of these tubes are not available now.  Moreover the circuit boards are  dangerous to handle,  due to very high voltages  present on them,  while the set works. The picture tube is a Shadow Mask type,  need very high voltage,  in the range between 27 KV to 30KV, and have more than 33 alignment points.
