Jensen Imperial Crossovers

[hammondman]

Hey guys, I'm putting together a pair of Imperials. I was wanting to rebuild the crossovers but the tar has covered up the the old capacitor values printed on the capacitor. Do any of you know the value of the caps used in the A61 and A402 crossovers? Also, is the M1131 really necessary in the imperial because it was never used in the G610.

Ten years after your OP...did you get any answers? I just scored an Imperial and have the same question. I did find a schematic for the A402 4000hz that had (2) 1.75 mf caps and (2) .9mh coils.

I just posted to the other thread where you've asked so I don't know if there is any point in answering here also, but if someone finds this thread years from now googling I guess I'll just post here too.

Not super high quality but legible:

Those numbers (both posts) come out about perfect for the 4kHz & 600Hz constant-k 16 ohm values using the "standard" m=0.6, FWIW.

I don't know what's in that M1131 EQ can, but it's only applied to the RP201 load and not the triax. If you are using that RP201, maybe the Decware board still has all that stuff (?).

Thank you both!!!
