Corrected.
A brief question for the gurus. On a 1986 SRS crossover, which 20uf cap is The shunt on the low pass? New Clarities due tomorrow and I don’t remember which location on the board. Did a search. Don’t seem to find it.
TIA

    There are no 20uF caps in the high pass

    Oops. Thanks. What I am looking for is to ID the 20uf shunt cap in the low end. Sorry for the mix up.

    It's the two per crossover that say "20 uF" on them.

    Understood. One is a shunt and the other is in the signal path. I don’t remember which location on the board is which.

    Follow the tracers on the board. It's the one not linked to the two 130uF caps.

    Both 20uf are shunts.

    The dimensional one is a bypass cap.

    Not according to the posted schematic. The two 2.75mh coils and 20uf caps both form separate low pass filters. One for the stereo woofers and one for the dimensional array woofers.

    I'll drink to your shunt if you drink to my bypass...
