Hi. Longtime lurker, first time poster.  Looking to build a couple of 109s, but I'm wondering if there may be a few mistakes on the published schematic.
It's at the top of this thread...

My question concerns the high & low shelving.  When switched to shelving (caps out of the circuit), it appears that the 50 & 100 Hz settings are using the exact same RL values.  Same thing with the 300 & 400 Hz settings.  Similarly, on the high end (with the inductors switched out), the 7 & 10 KHz settings are using the exact same RC values, as are the 12.5 & 15 KHz settings.

Am I missing something here?

Thanks,
Tim
