content: After doodling around with class d amplifiers for some time i have decided to go back to where it asll started, the Class A amplifier, but won't discuss it any further here.

content: What you really want is a class AB amplifier. Carefully designed, they give outstanding performance and have a very small idling current.Class A amplifiers are easier to design and build, but they're horribly inefficient.

content: NO! I do NOT want a class AB amplifier. I have already built more class ab amplifiers than i know what to do with and will not take this discussion any further on this forum.

content: QuoteNo Class B/AB amps will leave class A at clipping. If Class B amps fits that bill.QuoteThere were those "variable" / "sliding" Class A amps (that alter bias with input signal). What ends up happening is that people quickly realized that you need a far better amp to alter the bias than the amp you are tryign to build.As a result, they have go out of sight for 40-50 years by now.

content: QuoteYou wouldn't know if you don't try.What this forum is NOT is that people here are not expected to wholesale take whatever other people give to them. You will get a lot of perspectives, many of which will differ from your own.If you value other people's views and feedback, this is the forum. Otherwise, no.

content: What the hell happened in this thread? To the casual outside obcerver, it seems the OP didn't like that people were voicing their opinions while helping...@ the OP: Why would you post a thread saying that you are leaving a forum? Also why are you so set on a class A amplifier instead of class AB or better?-kizzap

content: Quote from: c4757p on October 16, 2013, 03:23:11 amClass A amps easily drive electrostatic speakers for that sweet sound. (low impedance at high frequencies is a challenge) Mine is 150 Watts per channel. Very inefficient, gets really hot, couldn't care less.Love beer, especially Belgian.couldn't give a hoot about people who criticize class A amps and beeryou need a Kwak

content: Quote from: c4757p on October 16, 2013, 03:42:48 amI was never a big fan of beer (there, I said it!) when I was younger. One stinking hot day working hard and sweating profusely on the hot deck of a ship, we were invited up to the ship's bar and offered a cold beer. I could not imagine anything more thirst quenching and satisfying. Needless to say, big fan since then
