Summary
Late '80s consumer Trinitron. Features a true 20" tube, one composite A/V input, and a set of variable audio out jacks. The KV-20TS10 is similar but RF-only.

Notes
It was also one of their last TVs of this size to include a pincushion correction circuit, and has adjustment pots for horizontal geometry.
While this TV does have a remote, picture adjustments are controlled by pots on the front panel. Unlike some Trinitrons from this period, the TV can be set up properly without it.
Despite having A/V inputs, this TV uses a hot chassis design and should not be modified for additional inputs. Instead of isolating the entire TV, the input signals are transmitted using optocouplers.
This CRT is confirmed to be a hot chassis.
Hot Chassis means that "ground" on the chassis is tied to one side of the AC input from the wall, and touching it with your hand will complete a live circuit through your body to earth ground if the CRT is plugged into an AC outlet. The proper way to avoid this danger is to use an isolation transformer to isolate the CRT from earth ground and prevent electrocuting yourself.
