You're right. The question comes up every few years, and 
nobody has ever produced a schematic.

If you slide the unit out of the case, you can easily see 
how it is put together. Basically, there are 6 bpf's in 
series. The ones that are not activated are bypassed by 
normally-closed relay contacts. The bpf that IS activated 
has the relay pulled in, putting the filter in line. The 
discrete components for each bpf are easily visible, and can 
be easily worked on.

I have the capacitor values if you need them.
