    An Educated Guess?? It has the same values as N500C

    In the absence of someone else posting a schematic, my best guess is that it's simply a rotary-switch development that uses the previous model's values ( iow; Altec N-500-C , whose values are mostly unknown excepting what's seen in the following N500C pic showing 2 x 18.9uF cap values ) .






    My guess is that the inductor/choke values ( inclusive of N500C through N500E ) are all 5.4mH ( considering that the odd-ball 18.9MFD capacitor value was still retained within the woofer circuit of the N500E ) .

    Altec started out using the buss-bar approach ( for the Lpad attenuation ) and then changed in the next model to the dual-ganged rotary switch ( to accomplish the same thing but in less room ) > & then eventually switched back in the N500F .
