Here's an opportunity from the esteemed amp gurus who hang out here to enlighten some of us normal guys. How can you determine if your amp is class A? Using a multimeter, is is possible to determine an amp's class of operation? How do I do it? In order to head off certain responses, let me say I'm not caught up in the class A hype. My amp maker's marketing says my amp is class A (Savage Rohr 15 - dual EL84, cathode biased, push-pull). Whether it is true or not, I do not really care. However, it would be fun/interesting/informative if I could identify operating class myself. In asking this question, I'm trying to learn about amplifiers. This is not about exploding marketing hype or about being sure I buy a real class A amp!
