Sorry about this incomplete message. It was erroneously sent. I think the

That, it would. Stanley makes (made) good stuff, and 28 years ain't

Might be worth checking to see if there's a diode or rectifier bridge in
there. A shorted diode could cause AC to be fed to relay coils expecting DC
which will make them chatter or buzz.
