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!

To my ear, pentode gives me the impact on the head of the bass drum, while the triode pulls me into the middle of the tone. Pentode offers punch, while triode is seductive.

Just my 2 cent ears...
