Current, not voltage, is what needs to be set. Even carefully matched tubes will exhibit some differences.
When a bias supply and trim pot. are employed, the exact total bias voltage is not known. What is known, via Ohm's Law, is the cathode current.
IMO, combination bias is "best", when PSE O/P tubes are employed.
