In tube radios I have never seen a ratio as low as 3:1. Which would mean that even an 8 Ohm speaker would present as 72 Ohm impedance to the tube which is waaaaay low.
Your typical ratio at least 20-30.
Of course if your power voltage is very low and output currents high then it is possible but then we are talking transistor level voltages.
