Hey all

Attached Leslie 860 schematics below.

I would like to add a subwoofer out to this cabinet so i can drive a powered subwoofer.
There are not enough lows from the installed 12" JBL

Can anyone tell me where to start?

 

I would take the subwoofer audio feed from the Bass volume control, terminals P9, S11.

And that signal would be a line level audio signal ?

 

Don't know, where's the full circuit diagram, if it is then is that a problem?

 

If you want to be able to adjust the subwoofer level, you could take the signal from the pot output (where is says 0.7V).

 

Do you know if the input signal has any deep bass sounds?
