Did you tear it apart because it failed (if so what was the failure) or just 'because'?
no. just for fun, i still have some stock for that 200 ohm trimpot and i find it the least used part. and i was curious on inductive effect of it. i guess not suitable for ghz range of application, similar to original Bourns since they are the same geometry construction. but on some of the other Bonens immitation that already in a circuit, i detected some discontinuity at some place usually set during operation, but not so serious for me to take it apart so far, a slight turn will get it back inline. i cant 100% blame on the components since its maybe my design is flawed, i havent analyze its heat dissipation spec.
