That is extrapolating theory without understanding it.

Yes, the base material on octal tubes has more voltage leakage than an all glass tube.

Yes, the practice of rings and ridges on high voltage terminals does retard flashover and leakage by increasing the physical distance.

However that does not mean the small ridges on an octal tune base are there for leakage reduction. That is merely your guess.

IMPO, those ridges are mechanical support between the pins so the base doesn't break from the tube insertion force. The ridges are far too small to have any beneficial electrical benefit.

Just like your previous posts about group delay in black wire insulation you have no idea what the complex engineering terms you site really mean.

Why not get more electronics education before making these outlandish claims.
