I am doing some repair/ refurbishment to an SAE E101 electronic parametric crossover from the 80s
In the final stage there are NP caps in the audio chain; six 10uF/16V and six 47uF/6.3V
They are before and after three 5532 OP amps
I have never seen this before, do I need to keep them NP or is there an alternative ? Why have I not seen this before?

Yes keep them bipolar- lower distortion than polarized electrolytics - see Cyril Bateman’s articles if you want testing and an explanation
Some people say the best capacitor is no capacitor. In some circumstances coupling capacitors may be dispensed with.
I believe that ES is the same as UES. In some places the "U" is added before the "ES", other places it is not. I do not know why, but I have seen it listed both ways. It is Nichicon's audio grade bipolar electrolytic with a green sleeve. Available at Mouser and Digikey
