Ejman,
another important thing to remember is that the bias of a tube amp takes 30-45 minutes to settle down after switching it on. During that initial period the tube bias voltage is all over the map so you shouldn't even bother measuring it until it settles down. Hopefully you already knew this & you were measuring after atleast 45 mins....
I used to own a Jolida 502A some time back but I have forgotten what the bias voltages for the output tubes were supposed to be.
