How would a 7025 electron tube operate with Pleiades bias?


Yesterday a car had stopped at just the right angle so that its number 7025 could be seen.


From some experience with the 7025 electron tube, see Pleiades (-1)? the 7025 can operate at say 18V with just a suitable choice of low cathode resistor and underheated cathode.


How would the 7025 sound like on a Pleiades V6 anode to grid bias circuit and a much lower plate or anode potential?
