Those sets put a lot of beans on my table in the 70's. They've got a lot of nice features with that remote setup. They use search tuning (signal seeking) and have an automatic off feature that turns off the set after the stations went off the air. It samples sync pulses and uses them to hold a transistor in cutoff, lose sync pulses and the transistor conducts charging up a capacitor, when the voltage reaches the firing voltage of a neon lamp it triggers a relay and turns off the set. Low contrast, dark picture is a symptom of the second video tube failing, it's usually a 6EA8 or in later sets a 6LM8, it's the last tube on the right of the IF strip. That particular set probably has a T920 or possibly a T931 chassis which was a real workhorse for Magnavox and was used with refinements through the 1972 models when Magnavox went solid state. The remote is ultrasonic and uses an Eveready 206 9 volt battery. It's located about 500 miles from me and I'd like to have it but with $3.00 gas going after it would get kind of pricey....
