I have a Sunn Coliseum-300 bass haed (solid State) hooked to a Sunn 2x15 cabinet. It is a 300 watt RMS amp head. I acquired it in the early nineties and still works great. Is there anyone out ther who can help me determine the age of the amp. There is no indication anywhere aon the amp tto determine the age. It has black grills on the speakers and all writhing is done in silver. Any help you can give me would greatly be appreciated.
Thanks
Mikey
