need a owners manual for Marantz PM-54

need a owners manual for Marantz PM-54 I see there are many different makes of the amp and most of the pictures look different some gold some black some with Marantz printed some with a name badge ? The one I have is a PM-54 no SE, it is gold and on the back it has made in California ?
Any help would be very nice
thank-you
