Hello ,
Remember voltage drop across the output transformer , these designs may be cathode bias so the overall anode/screen to cathode is probably a lot lower than you think . Fixed bias is another matter , as long as you can dial in more negative bias at higher screen voltages you should be ok , may be an idea to gradually measure and rebias as you increase the screen voltage . I think 6L6GC have higher screen grid ratings ratings than a 6L6 :)ps I forgot to mention . CV4060 can be strapped as a triode with either the beam plates tied to the anode or the cathode , like what can be done with an EL34 . I prefer G2 and beam plates tied to anode via a 100r resistor , if you try asa triode consider both :)
cheers
