You are absolutely right about pseudoscience.
This here 500C is a tube gear, and the vintage tube is a disappearing lore, so it does pay to heed the experience of the older folk who dealt with it in its heyday. I know that me being an EE, I don't know about the tubes and their application nearly as much as some guys here who are not even necessarily formally trained in electronics.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
