    Rski-I was refering to the transformer shunt method of measuring the bias not unsoldering the leads.As far as dividing by 2 to get the plate current for one tube if you are using closely matched tubes the difference should be negligable,and by closely matched I have found, and many techs agree, in a guitar amp +/- 5ma is good enough,if you feel they need to be closer then you would have to check each individually.
