[Amps] SSR in amp PS not working as expected

I see. Now I got the datasheet, and indeed you have the wrong kind of 
SSR. It's a zero-crossing triggering one, AND snubberless. If you had 
gotten the -10 version (CSD2425P-10), which is instant-triggering, it 
would probably work. And if you got one that also has a snubber, or else 
if you add a snubber, the chances for correct operation with inductive 
loads will increase.

Note that the datasheet, which is for several variants, even spells out 
that the zero-crossing triggering versions are for resistive loads, and 
the "random fire" (I prefer the term "instant triggering") versions are 
for inductive loads.
