Question Mains filter QS

I'm planning to make simple four inlet filter, using Shaffner FN 2080 Multistage High-performance Filter. Would it be enough to get 10A version for use with: CDP, AMP 50W Class A, DAC, Headamp???

Hi,
how many watts is 10A equivalent to?
How many watts do you expect to draw continuously?

I think 10A is a little big. You lose some attenuation in return for extra current.

I guess about 200W

I thought the bigger is better...

Is your mains supply coming in at 220Vac or 110Vac

What is the individual power consumption of each unit you need to connect to the filter?

I think 80W Amp, 50W CDP, 40WDAC, Headamp 30W

Hi,
your consumption is about 200W as mentioned.
That needs a minimum of a 1A filter not 10A.
You could try to find a 2A filter to give some peak ability and prevent any risk of overheating.
Or split the load into lower consumption sources and higher consumption units and then fit two 1A filters.

BTW. check your dissipation in the ClassA amp, 80W input for 50W output does not add up.
