Hey everyone! I have been google searching for weeks trying to find out what the wattage rating is for a 1976 Ampeg SVT 8x10 Cabinet. It has only one 4ohm 1/4" jack on the back. I cannot find any useful information about this despite all of my google searching. I want to make sure that I will not blow out these speakers as they sound awesome. Right now I have a Peavey Delta Bass head running it and would like to move up to something better but not knowing what this cab can truly handle I am a little cautious. Thanks for your help!
