Any Revolver turnatble owners here?

I have the old Revolver's Rebel model from the mid 80's and I'm looking for a clamp. Does anybody know what would be the maximum clamp weight for this model? I have contacted the people at Revolver and they say 120 grams. The person who answered me is new and it seems he doesn't know much about turntables so I'm wondering if I could use more than these 120 grams?
Thanks.
