Default Q Multiplier

The circuit calls for two 10kΩ pots for null and peak, doesn't specify log or lin, what would you use?

If you're referring to an equaliser circuit then a pot with linear law is most used.

Any chance of a peak at, or link to, the circuit please?

Yes, the circuit is here. I'm hoping to use it with my BC454 command set. It just needs adapting for a 1415khz i.f.

Make both linear. They will have a sharpish point where the action happens, and a log pot would make the interesting zone narrower.
