Resonant Circuit
(OP)
Been 35+ yrs since taught and haven't used since. Outside my office is a plant loudspeaker. It has two wires powering it. The PA system was changed to where there is a very loud and annoying 1000HZ tone just before the message. I would like to filter out the 1000HZ with a choke coil and a variable capacator. Could someone plug in the values and whether it would be series or parallel. If this idea won't work is there anything I could do to disable this tone locally and not at the main amp?

You will have other problems if you try to filter out this passband.
You would do much better finding where the hum is coming from and fixing IT instead.
