This is about an AER Compact Mobile2 acoustic guitar amp
Recently it started to blow fuses after a few hours of playing guitar. Until a few days ago that it started to blow them instantly when powering it up
There’s a mains filter inside the amp that it is shorted (fried). Bypassing it the amp plays just fine. But I don’t know if I can find the same one
Should I replace it or leave the amp without one? Is this a common 250V 4A mains filter. Do I have to find exactly the same one?

Might be able to find a replacement if this one is not an option. If it is a shorted part you may be able to replace it.

I would replace it as being a switch mode power supply, it causes interference down the mains lines and will stop interference from the mains.

Printer2, the one you posted looks like the same with the one I’d like to replace.
But way more expensive than the one JonSnell Electronic posted.
As I understand, a common EMI mains filter will do the job just fine.
Any other European source? Henri shop ships only to a few countries

I thought it was priced higher than I think it should be but if it fits the space of the original it might be worth it unless it is not inconvenient mounting a different one. It has the same part number if I remember correctly.
Finally the amp is ready and running with a new filter. I replaced it with exactly the same one
I did a lot of search about this and I even sent an email to AER. They were very helpful and they strongly advised me to replace it with exactly the same filter. Their technician said that it’s not a common EMI filter. It’s a CPM filter and works exactly the opposite way of an EMI filter. Also the filter must be precisely matched to the oscillation frequency of the switching power supply
