The only thing that happens in FM mode is that the CRT brightness is cut off. All the TV circuits are still running including the high voltage.
So you really are wearing out the TV tubes and CRT while just listening to the radio.

I have a 15" RA103 or 104. It has the regular Dumont chassis, with the inputuner and FM radio. It also has a record changer and a AM radio chassis.
The strange part is the phono audio goes through the TV chassis. The radio is only used for AM radio reception. It's a six tube job, with a tuned RF stage.
Both chassis have a SE 6V6, output stage. The selector switch on the radio, cuts off the power to the TV chassis and switches the speaker to the radio chassis, when it's being used for AM reception.
I, personally, would have used the radio chassis for record reproduction.
