The power cord plug on the amp side seems quite unique and different from all the other brands I have had. If I am going to get a shorter length replacement, where do I look for?
It’s a regular IEC socket?
Yes. But it is not the usual C13 with 3 pins here in north America. It is the C17 type instead.
Yes, but C13 works with it very well.
It’s a class 2 device, so doesn’t need earth wire/grounding.
I tried a lot aftermarket power cords and the provided is not bad. BTW no need for the third earth cable, there is not connection inside the amp.
