Triode vs. Pentode


I've been switching between Triode and Pentode modes on my VAC amp during the past week. This has been my first experimentation between the two. I'm having difficulty discerning a clear difference, and I'm enlisting the advice of you tube heads to explain what I should be listening for...

Thanks in advance!

Zaikesman- The best post I have ever read on the subject. Like my Atmas or my Cary; emotion and truth. Sciencist and philosopher. I am humbled. I have no idea if the technical details are correct, but I understood! Kind of like a triode tube amp.
