pure class A?

Thanks for the responses. I have a little bit of a back ground in electricity. So, I believe I have a pretty good grasp of what you're saying.

Thanks again,

Damon

Audiofile9, what you describe is known as a push-pull arrangement in terms of one output device "handing off" to another device as the signal changes polarity. These types of devices, especially SS models, are typically sold or marketed as "complimentary pairs", etc.. This somewhat assures near identical operating conditions for each polarity of the cycle. This is very similar to the way that running matched pairs in parallel assures that they share the load equally. Sean

Sean, your the man. I've read numerous descriptions on the differences of "class", but yours is the most lucid and succint yet. Thanks.

Unsound, right on! Sean, thanks for the clarification. If you would be so generous, perhaps you could explain the difference between "Single Ended" and "Class A" (and how "push pull" relates)? I've always been fuzzy about the differences there. Perhaps like many others, I assumed Class B was synonomous with PushPull, etc. Have seen the many threads that touch upon these subjects, but have not found any bearing your excellent analogy as above.

Audiofile9 makes a very good point (request). I once recall someone telling me that while you may understand something, the true test is being able to explain it in simple terms to others, so that they understand it. That said, I felt I understood class B vs push pull, but clearly Sean's articulate analogy shows he REALLY understands this concept. And while I also feel I understand "single ended", "triode", "pentode", and "OTL" I don't think I could do the explaination justice--but hope that Sean will.
