Can someone send a schematic of the JBL L-77 crossover? That would include cap, coil, resistors, and l-pad hookup.

Thank you for the JBL L-77 crossover schematic. Do you know what the impedance is for the 3 position switch?
The three position switch is just a rotary switch, it isn't an L-Pad. The high pass is 3 kHz with -1, -5, and -9 dB of attenuation depending on where the switch is set. The resistors were each rated at 11 watts.
Do you know where to purchase such a rotary switch without trying to buy from JBL?
You can get one from Mouser

It is an adjustable stop single pole 2 to 12 position switch. Y ou can set it to have three positions.
