To answer your question, nothing anymore, as I am about to explain.
UHF tuning in a TV set has no use any longer in this day and age of digital TV, as all older CRT TVs must now use a converter box with an antenna or cable to receive DTV signals. Most U. S. DTV stations broadcast over UHF channels, but I don't think they can be received using a standard (built into the set) UHF tuner or outboard converter as the transmission standards are different (the UHF tuners in all TVs made since the FCC UHF mandate of April 1964 are designed to receive only NTSC TV signals). These tuners or converters may not (more likely will not) work with today's ATSC DTV, although the broadcast frequencies are identical -- UHF channel 25, for example, is 536 to 542 MHz regardless of whether an analog or digital signal is being carried over that channel.
Note that since the DTV transition, UHF channels 51 through 69 are now assigned exclusively to DTV stations; NTSC analog television stations operating on these channels have been required to relocate to lower channels or else go off the air. Channels 70 through 83 were reassigned to land-mobile use in 1970, again requiring all existing TV stations operating in this part of the UHF television band to relocate to lower channels or cease operations entirely. Some early (1950s) UHF stations also operated on very high UHF channels above 70 (one of the first TV stations in Youngstown, Ohio for example, which would eventually become an all-UHF market, began its operations on channel 73, IIRC, when that station signed on in the early 1950s; it later moved to virtual channel 21, where it remains to this day).
BTW, I looked at one of the pictures of your Magnavox stereo theatre and found that there is no radio included in the console, just a Magnavox "Micromatic" four-speed record changer and, of course, the television. At least I didn't see a radio tuner anywhere on the control panel; if there is an AM or AM-FM radio in this unit its controls and dial scale may be located somewhere else on the set, although I would think that since most consoles route the phono/tuner audio through the television's audio amplifier and speakers, if there is a radio tuner in this one its controls would be in the same general area as the TV control panel. Another possibility could be that whomever owned this TV before you may have, for whatever reason, removed the radio tuner while leaving the amplifier intact and operational, although I did not see any empty holes on the control panel that would indicate such.
