VERY loud hum issue

[5th element]

Silence is golden

Ive finally got it all silent woohoo!!

Anyway it was a trimpot thats lets me adjust xover freq only one one of the three pins was connected to sumwhere it shouldnt have been, well to ground.

This wasnt a problem with battery operation but obviously without.

Well there we have it problem solved the lot sounds wonderful. Thanks for all you help in helping me sort it out.
