Yes- it is best to avoid any differences of voltage between the elements for best results. It is possible for example to contaminate the grid if its voltage is significantly different!
Higher load impedance seems like a easy solution, but not a practical one...if only you could materialize the 32-50 ohm speakers the article mentioned, more power would be available...
Kinda like electronic alchemy, I guess...
(My reply makes no sense (even to me) now because I was responding to the interest in higher power, but the thread has evolved to variant topics related to this amp...)

Do you have anny practical ideea how to clean the terminal pins of the 6c33c, as they are preaty rough after more than 40 years of sleaping in some military warehouse....
By the way, in the rombus seal of that lot is No. 27 (QED)
We use 600 ohm 3 watt devices. Sometimes the tube can arc and put considerable current through the grid stop devices so they should be able to handle a little bit of power. So far none have failed and they've been in service for years. No hint of oscillation either.
