Anybody have experience recapping a snell Jii crossover. Ive seen threads where people mention them but I haven't read any details about doing them. I feel like its time to redo them to get better performance. any ideas on what will make this a worthwhile upgrade

Just note that Peter Snell put together those cap bundles for a engineering reason and not just economics. My recommendation is to not replace a bundle of NPE's with a single film cap.
 
Do you have a reliable schematic? If so, please post it. I'm working on some JIIs also, but the schematics seem all of the place.
 
Here is a schematic I drew some time ago when I worked on one. As you may be aware, Snell 'tuned' each XO for each speaker, so the values I measured may certainly not be the same as yours. The bypass on the tweeter bundle was a film cap, but the 2 uF and 8 uF caps were NPE's IIRC.

Perfect. Thanks. My JIIs are currently missing crossovers entirely, so anything is better than what I have!
