DEAR TOM,
	I think Gralab sent me to Quality Light Metrics for the 50 Hz
motors.  georgepmilton at worldnet.att.net 
	In Barbados we also have 50 Hz line current.
		CHEERS!

I have an old Gralab timer which I bought on ebay. Excelent piece of
hardware and yes, I usually turn the minute hand counterclockwise with no
apparent ill effects.

The problem is that it expects a 60Hz mains frequency while here in Spain we
have 50Hz. I have heard somewhere that the synchronous motor can be changed,
but how? Does anybody know? Alternatively, does anybody have their mail
address?
