Hi pkvintage,
I have Snell E II’s and sent you a PM. Erik gave me guidance when I tackled the crossover. I would follow his advice and replace the capacitor bundle (should be 5.6uf) in series with the tweeter with a good quality film cap (Clarity CSA or CMR and Erik would probably recommend adding a .01uf Audyn True Copper bypass). Without test equipment I would just replace the old NPE’s with new NPE’s and swap out the sandcast resistors with Mills.
