All I can say is that the fuse in the amp I'm in process of repairing was a 2A(T) one, and in the circuit diagram I downloaded it iis shown as being 2 Amp. Maybe it was changed during the production run, which, if I understand correctly lasted almost 30 years. I didn't time it precisely, but the rectifier flashed over, blowing the fuse in no more than a minute
