I just looked inside my 720A at the 20 turn 5K trimpots. They are
Bourns 3005P-502 printed on them, cermets, standard 3/4", tempco 50 ppm.

came from here.
Perhaps from the Bourns 3005 DATASHEET I posted a couple of days ago.

Digikey is $14.35 and Mouser is $14.35. Wow! Expensive little devils.
On the other hand (left) Digikey shows a unit from "TT Electronics/BI
Technologies" for $1.40 ea. Interesting. Why such a massive difference in
price?
Cermet ($1.40) vs wirewound ($14).
