Put a small table/alarm clock on top of it, or a wall clock to tell the time.
The more DIY options are to make a battery back up for the time keeping circuit, or replacing the clock with a LCD car clock, if the clock has no function other than telling the time.
My advice is to leave well enough alone, and enjoy the music.

Expensive in terms of power consumed, and also dangerous for the unit in case of a power surge.
If time display is not important, leave it off at the mains, from the wall switch.
Think about how much effort it will take to fix it, most parts are not available.
Except in the USA, I have not come across mains frequency being used as the time base for electronic clocks, the actual frequency here is 50 +/- 0.5 Hz, at which point the power distribution sub station is tripped by a frequency relay.
So your mains frequency operated clock will not be accurate.
With 15 W standby power I would also use the Netz switch and not use the clock.
Off-topic: clocks using the mains frequency as timing reference are quite common in Western Europe as well. I have two of them, a digital alarm clock radio and an electromechanical one with a synchronous motor. Though not as accurately as a clock with a trimmed crystal oscillator, both work well because the long-term average mains frequency is well-controlled.

...except a couple of years ago when there was some conflict or other between power plants in the Ukraine and they deliberately slightly reduced the mains frequency, which affected most of Europe. I don't know the details, but both the alarm clock radio and the electromechanical one were lagging by several minutes.
On the left of the front panel there's a switch marked "Netz Power", and to the right of it one marked "Aus Off". I've just been using the Netz Power button, but I think this should be left on all the time, and the Aus Off button just used for turning it off (putting in standby mode)?
Correct.
I'm leaving it well alone now, as I think I know how it should work.
I will leave the Netz Power on, and just use the Aus Off, as this retains the time. If I won't be using it for quite a while I'll use the Netz Power.
I think you can use the clock to set up timers (see the section to the left of the display), but I won't be bothering with that.
Thanks to all, Rob

I have at least 5 line-controlled clocks still in service. A sync motor used to be very affordable and very-very long-lived. The one in the bedroom has a pre-1962 power cord. I used to have 6 but a line-sync digital clock radio started skipping beats and losing a minute a day (I could figure it out but why bother?).
I would even say they are more accurate over time than any cheap crystal. They do not so much control the frequency as the cycles per day/month. Today it is all coordinated so the -network- all pulls together (or not, if Ukraine is lagging).
But precision frequency control goes back much further than networks; indeed to the early electric clocks. Once we had clocks, the utility was expected (fairly or not) to keep good time.
When my father had his first job the engineer of the isolated power utility in Missouri had a very fine pocket watch. Every morning he checked it against the clock at the railroad station, which was wire-synced from the observatory at Washington DC. In the power plant was a good sync-motor wall clock. Each morning he compared the watch to the clock and made an adjustment on the dynamo governor to reduce the difference over the next 24 hours. Such schemes could be relied on for a minute a day, and 10 seconds a day most days.
A crystal may be good but it does not cross-check with celestial observations. (Except when the battery goes flat and the user re-sets the clock against radio, phone, or other good time.)

I had a Braun alarm clock with a 4.19 Mhz crysral, 4 seconds per year accuracy.
And my client used to put 2 ppm instead of the regular 6 ppm 32768 Hz crystals in his clocks, and insist on Citizen or Murata in metal cans...
Effort counts.
Anyway the poster had his problem attended to, and now onward to the next problem...
