Cem3340 four trimmer tuning

I can’t remember if I’ve written about this before, but there is apparently a way of tuning the CEM3340 (and AS3340) that is done in a single go, without the need to go back and forth between different potmeters. The downside is that it requires four trimmers instead of just two. Also, I don’t know exactly how it reacts to temperature changes.

The procedure is described in detail (with explanation of how it works) here:
