A NAP200 should come with a 4 pin SNAIC - and, yes its socket does carry +24 V DC, to power a PreAmp (so long as the Pre has its Blanking plug in its 5 pin DIN socket - which is where a HiCap would connect, via a 5 pin SNAIC).
In case this helps.
I have a 252/SC running with a Nap200 as I wait for my wallet to recover before heading down the “settle” for a 250 or go all out on a 300 spiral.
The setup runs fine with a snaic4 between SC and 200 as almost shown with the 282 setup above. You should already have this lead with your 200 so will only need to buy the burndy and snaic 5 for your 252.
