What makes difference in some amps?
I have been reading watching you tubes, and the Ameritron amps AL-82, AL-1200, AL-1500, the 3 amps have same transformer, but 2 of the amps share ceramic tubes that's are very very expensive but last, the other AL-82 has a pair of 3-500z's glass tubes yet see all 3 perfom toto 2k to 2.5k+, explain why one would be better than the other in short and long time running. To me the AL-82 seems best with tubes running @300 give or take a pair vs 900 to 1900 a pop.
Are ceramic tubes that much better for the expense of them?
