Hey sammas thats nice and quick. I'm wanting to do a layout for a pre/eq on one board but yours sounds cool.
I think you are correct, concerning the inductors and switching. If you used wilco inductors you could have separate ones for each freq, as opposed to having a tapped job. I think this would allow for more closely matched curves at all freqs....maybe, maybe not a good thing.
As andy said originally, the Sowter LF Neve inductor has three taps and should give something like 50, 100 and 180Hz on the LF. Its expensive at approx 35 quid.
The cinemag is cheaper but not tapped I think just 1.2H? So different caps will be switched for the freq and the curves will change slightly I think(?).
Wilcos will take up more board space and I'm not sure about purchasing from them but they would have enough values for both the LF and MF....
3 LF freqs
6 MF freqs
3 HF freqs
would be cool and require two 1 pole 3 way rotaries and a 1 pole 6 way...lorlins would do.
