Doc.

Electronics layman here..

Does complimentary output split rail mean "push-pull"

Cheers

Alfi.

It does with valve amps. Marco has a push pull valve power amp he tells everyone is class A, same lies it is class AB.
Can't forget that. Where I fell out with him by agreeing with you on HFS. LOL. Just can't understand people who think having class A gives them brownie points. No wonder manufacturers call amps Class A if they can get away with it. Amps heavily biased into class A get very hot and best not left on. MF A1 toaster comes to mind.
MF F15's can get a tad warm too.

Yes they are lying as we have discussed here before recently, and the lie has been used so much it has become common amoungst hi-fi people. You see the problem is a class B can be biased to simulate class A, which is why it is called class AB, for part of its power range, even up to fairly high levels by setting a high bias current on a class B amp you simulate class A. That is why it is called class AB, but the class A is not the same as a true class A which is single rail and single ended, the Monarchy and the Krell and many others that tell this lie have complimentary output stages and split rail so are class B, as I say the bias makes them AB. They are not real A and can never be real A, they are AB - full stop.

It is a marketing con job and a lie that has been used so many times it has almost become accepted, apart from by people who know it is a lie. We have a hobby now dominated by bullshit, this is just one example, we will point out many more as time goes on.
Well it like adding "Ology" to words to make it sound impressive and new, "A" Class implies now days it is good and wonderful. Like Gay means happy.
And like German Cars with two brains the cars and the driver, shame the human one is normally here OFF and the car is not telepathic so no signals etc.

So we can have "Cabology" and "Ampology " next and of coarse "Crappology" for digital crap. Cool. :hbs:
It can be done so imagine it.

My Rega Elicit-R is described as having: "a low source Class A driver stage, based around a complementary pair of Darlington output transistors, forming an emulated Class A driver stage". No idea what that means or if it is 'better' than being Class A, Class A/B or anything else, to be honest. Sounds great though, doesn't it?! :grin:

I had a sneaking suspicion that might be the case!
