The smaller one was poorly manufactured. It was whining. And now it's value is dead. What was it before? There was no value on heat shrink.

If you have decent experience in soldering, you can unsolder the coil, unwind at least the several top winds and rewind it again tighter and solder the wire end back to the terminal. If you want to completely replace the coil, you can use even a cheap tester like this https://www.ebay.at/itm/All-in-1-LCR-Component-Tester-TransistorDiode-Capacitance-ESR-Meter-Inducta/402624957700 to measure it (you have to remove the insulation on the end of the dangling wire). Then replace it with a similar coil.

If you have no experience with this or doesnt know anyone who does, just buy a new one as many recommended.
