Hi, Steve Thanks for the links

Im checking another option that are the Lighspeed made of LDRs.

Btw If someone know something good or bad abt that pots, just let me know!

Another thing 10 turns will be not OK for my application.

In your 10K-20K-30K and 50K I only have the linear pots.

I have Bourns pots in 1 Meg, 500K, and 250K in the Audio/
log taper pots... seen here.

I'll hold your order awaiting your final add ons.
