New VHF and UHF Varactor Tuners

The VHF and UHF tuners are separate units, and each is manufactured and tested by itself. In the television instrument they are electrically interconnected and, in effect, comprise a three band, all channel, varactor tuner. In those instruments using the electromechanical channel selection system, the two units are mounted together with brackets and interconnections so as to provide a single V-U unit. In those instruments featuring the digital direct address system, each tuner is mounted on its associated address system module.
