Snell JII crossover recap help

streetwise

Active Member
I Have 2 Snell JII speakers im looking to rebuild the crossovers to bring them back up to spec. I don't know what kind of caps to use and what type of resistors would work best.
JII crossover1
100V 100UF
non polar 4mfd50v
8mfd50v
8mfd50v
2mfd50v
16mfd50v
16mfd50v
04-2030 D. A. 3.0J 100v MMM
M.I 20W .5ohm 10%
M.I 20W 4ohm 10%


crossover 2
100v 100uf
8mfd50v
4mfd50v
100v15uf
100v15uf
2mfd50v
8mfd50v
04-2030 D. A. 3.0J 100V MMM
M.I 20W .5ohm 10%
M.I 20W 4ohm 10%
these are the values in each crossover

test the the four resisters with an ohm meter. Look cracks or burns
these are most likely to be OK.

Caps : Dayton , Solen , Jantzen "POLYs"

… from: Parts Express for values 2 to 8uF , for 100x100 use NON POLARs

If you want to maintain the original voicing as much as possible. Rebuild each cap bundle just as you found them only with new NPE's and film where applicable. Peter Snell designed and built them the way he did for a reason.

If you are not as concerned about original voicing, replace with all film types.
 
Snell supposedly matched each speaker to within .5% of a "master" speaker...whatever that means.
I can only guess that is why the two crossovers are not the same.
If you are keeping the original woofers and tweeters (and you know the speakers are as originally from the factory), spkrdtr is probably correct.
Use the same values as what is in each crossover. And make sure each crossover goes back into the same cabinet it came out of.
