Sorry if this is a dumb question but I’m confused. I have a couple of PCBs in the works and a few of them have 5 holes for the cermet 3362p trim pot but the pot only has 3 legs. Am I using the wrong trim pot? What am I missing here?

Probably familiarity and cost...

Multi-turn is great for fine tuning but can be a bit annoying in a circuit where a wide sweep is desired.

Another (minor) negative of a multi-turn is that you can't visually tell where it's set.

I just used some multi turn trimmers for the first time in the destiny behemoth. Kinda blew my mind. I was trying to picture what’s going on inside there mechanically to allow so much adjustment.

The bias voltage I was shooting for was waaay off from the starting value, and I thought I had screwed something up, but like 20 turns later it was right on.
