My pd52 hums pretty loud. How loud is too loud? Wrap in insulation?

Check for loose connections.
Think about replacement as it will fail when you need it the most.
I tightened connections. No change
Is there a better model available?
Tightening wire connections, only insures a good connection that won't get hot and cause crystallization of the wires and other current delivery problems.
Pull the relay contactors themselves and use emery cloth and a small file for cleaning the contacts and where the coils make contact, as well.
Had to believe they're all making noise or that they all are bad.
Check the little springs on the arms, while you're at it.
You can always replace one with a like model, if really faulty.
With re-reading the thread, it seems that the deed has been done, so you might as well ask for the old one back for having a looksee and for having a spare, if needed.
