Same happened to us and Tilfords wanted 1200 plus to replace it.

Use the thread to solder the joints as per Marcs instructions. Buy a decent soldering iron and magnifying unit first.

I'm very short sighted so like a Trappist monk I did not need a magnifier..just took out the contacts😚

Had zero problems since....touching lots of wood tho🙄

We used a Goot soldering iron from jaycar.
