I just had a amp head given to me. It’s in very good shape but have no idea of its make or history. It’s a 2 wire plug It’s made in Canada It’s tube. The “grill cloth” looks very VoX like. I’d guesstimate 60-70s ish... Anyone have any ideas on what this is? Edit: I have just found an identical head less the painted on name and different colour grill cloth made by...Rivera amps”. No info other than that so far.
