Perhaps nothing, assuming the amplifier converts the AC to a DC signal. If this is done, the power supply may not filter the AC signal to as clean of DC as it did at 60Hz, which could cause a little bit of power supply hum.
To be 100% sure, a schematic would need to be looked at.
If it's any help, I was looking at a Vox Night Train. I don't have access to schematics.
Here's a link for schematics (might be useful in the future for you):

The bottom right has the power input; The "inrush device" I believe is a power capacitor, if it is an SL22, it is rated for 20A at 60 Hz. the amp is fused at 1.25A; scaling to max for 50 Hz brings it to ~16 amps, which is more than enough, so this is not at risk of burning up.
The secondary of the transformer splits off into two parts - the main and a lower voltage circuit for powering the input. BR1, Q1, and Q2 are rectifiers used to convert AC to DC - rectifiers "chop" the wave off so it is unidirectional voltage from the output of these, but it is not true "DC", since it will have substantial ripple. The capacitors and resistors to the left of these are used to reduce the ripple. So everything beyond this point doesn't really care what frequency you use. The impedance of the capacitors will be more at 50Hz, which will cause less ripple smoothing, which could result in some hum.
The real issue here will be the transformer - at 60Hz, less turns and/or a smaller iron core can be used vs. 50Hz (FYI, this is one reason marine power is ~400Hz - it allows equipment to be sized down). I'd find a serial number or data for this transformer, and look up whether it is made to run at 50Hz. If it is not, it will likely overheat. It may be necessary to replace with a beefier transformer to run at 50Hz.

What happens when power supply is overloaded?
When a power supply is overloaded, it can overheat and potentially fail. This can lead to damage to the connected devices, such as a short circuit or a power surge, which can result in data loss or hardware damage. It is important to ensure that the power supply is rated to handle the load requirements of all connected devices to prevent overloading.
How can you measure the ampere or watt for power supply?
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
Do you need REM cable to power up amp?
Yes, you need a cable to connect the power supply to the amplifier, but the specific type of cable required depends on the model and power requirements of the amplifier. In most cases, a standard power cord with the appropriate voltage and current rating will suffice. It's always recommended to refer to the amplifier's user manual for the correct power supply requirements.
Can a 12 volt battery charger use to power a 12 volts amplifier?
The battery charger can be used but it is not recommended. The battery charger does not have filtering on the its output like a power supply does. You will probably hear an AC ripple on the amplifier which will become very annoying when listening to the amplifier.
Why battery is required in UPS?
In an uninterrupted power supply there has to be a source of power when the electrical utility is not there. The only supply that is available is a battery that is in or connected to the UPS.
What happens to a 220v 50hz stereo amplifier when connected to a 220v 60hz supply?
Nothing happens. The stereo has a transformer that converts the power to DC, and 50 or 60 Hz input makes no difference.
What is a Dual Mono Stereo Power amplifier, and how does it differ from a standard stereo amplifier?
A Dual Mono Stereo Power Amplifier is a specialized audio amplifier that features two separate mono amplifiers, each driving one channel of the stereo output. Unlike a standard stereo amplifier, which uses a single power supply for both channels, a Dual Mono design ensures that each channel operates independently with its own dedicated power supply, providing superior channel separation and reducing potential interference. This results in clearer, more precise audio output. Want the best stereo headphone amplifier? Visit Accustic Art for the best stereo headphone amplifier.

What happens to a 120v 60hz stereo amplifier when connected to a 220v 50hz supply?
Destruction of the power supply depending on model it might affect the main board. The first thing the mains supply goes to, in an audio amplifier, is the transformer of the power supply. If you are lucky, just the mains fuse will blow, and protect everything. If you are unlucky, then the primary winding of the transformer will cook and destroy itself, needing a new transformer. If you are very unlucky, the higher voltages induced, will get passed to the main circuitry and destroy all the semi conductors.
What happens to a 220v 60hz stereo amplifier when connected to a 220v 50hz supply?
There should be no problem but you must check it to make sure the power transformer (the heavy component inside made of iron and copper) does not get hot while operating, because it runs at a 20% higher core flux density at the lower frequency.
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
What happens if a DC motor is connected to an AC supply?
Through loda
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Why does an operational amplifier need a power supply?
It doesn't. You can make a differential amplifier with a single power supply.

You want to buy speakers to use in Europe where the volt supply is 220-240v If you buy speakers in the US that work in the US are they compatible with European voltage?
If you are just buying speakers then they do not connect directly to a mains supply. Therefore, as long as they are connected to an amplifier with a suitable speaker output, they will work with no problem. On the other hand, if the speakers have an amplifier built in and are connected to the mains supply, they are unlikely to work on a 230V European supply if they are rated for a 110V supply. There are some exceptions to this such as multi voltage power supplies for example. If you are not 100% sure, assume that they will not work and avoid damage and personal injury.
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
