On paper, you want a pair of 20H 75mA, and half the capacitance.
But caps are cheap. If you stick with the 2-ch cap value in a 1-ch amp, you could stay with 10H (75mA) or maybe less.
As Johnny says, 10H and 150mA will often run like 15H when only passing 75mA. It isn't very critical, as long as you do NOT exceed the current rating, and the inductance is "close".

Hello,
better solution is to use chokes with the same losses ( doubled resistance), this gives at the same dimension of every choke a 2 times higher inductivity.
result: 2 times better smothing at the same losses per choke.
My preferred solution: Use one smothing for both channels with two CL-combinations in series, each with an half inductivity/dc-resistance of the original choke, then you will get much better smothing , at the same losses like before.
