Heising modulation and explain how it works?

Given a little bit of studying, yes. Do you want B or AB for the pp amp?

Heising is a plate modulation method for a type A amp.

Buzz, it's just different, not harder.

Ah, there is the key, "studying", not just memorizing. Once you study it
and know it, it isn't hard.

I studied for my extra test.

A person would have to be an idiot to memorize *especially* the Extra
test. You have some 800 questions to memorize. Not real smart to
memorize that many questions for all that appear on the actual test.

Especially when the actual test answers are juggled from the pool answers.
