Class G

[Sonce]

the 4b is not recommended for 2 ohm loads.

Really? Who didn't recommend that? When? Where? By the way, "recommended" is not the same as measured or used in the real world.

more than 90% of class AB amplifiers in the 70’s could not do 2 ohm loads well this is a known fact and youre arguing with me even going as far as saying i said something i didnt say.

Really? You said:

problems with 2 ohm loads 100% depends on the class of operation per the time in history it was built lol.

AGAIN 2 ohm loads ENTIRELY dependent on class of amplifier per the time in history it was built

Wrong!
Again: problems with 2 ohm load do not depend on class of operation at all!!! It depends on how many transistors are in the output section and what is the size (wattage) of the power supply. For tube amplifiers it depends only if there is a tapping on the output transformer secondary winding for 2 ohm load.
I gave you a lesson from history of amplifiers, but obviously you didn't read it. Here it is, again:

First class A audio amplifier was AT&T telephone line tube amplifier from year 1914.
First class AB audio amplifier was tube RCA Radiola Balanced Amplifier from year 1924.
As with all tube amplifiers, output transformer can be built for any load, without any other modification of the amp circuit: 16-ohm, 8-ohm, 4-ohm 2-ohms, 1-ohm, and so on... Often, output transformers have multiple taps for different loads.
So, class A or AB amplifiers, when they were first time introduced in history, were never troubled with 2-ohm load (or any other load)

Again: class A and class AB amplifiers, when they were introduced for the first time in history, never had problems with 2 ohm load - it is easy to get 2-ohm tap from the secondary winding of the existing output transformer (higher ohm load - bigger number of secondary windings). You should read some introductory book (for absolute beginners) about amplifiers.

more than 90% of class AB amplifiers in the 70’s could not do 2 ohm loads

You are contradicting yourself! If "more than 90% of class AB amplifiers in the 70's could not do 2 ohms load", then there are 10% of class AB amplifiers which can do 2 ohms load!!! So, class of operation of the amplifier is not important at all when dealing with 2-ohm loads! Simple logic!

class D amplifiers generally perform well with 2 ohm loads.

Well, if class D amp can deal with 2-ohm loads, and also class A and class AB (when they were introduced for the first time in history) did not have problems with 2-ohm loads (as I shown you), what on earth is your nonsense you keep repeating?

problems with 2 ohm loads 100% depends on the class of operation

If you came here to argue for argument's sake, you are in the wrong place.
The 'You Are Wrong" and I Am Right" attitude doesn't fit well within our forum. Life is not black and white.
First and final warning.

Few G class amplifiers in live audio that have a rather almost religious following.
Typically still working 30 or so years later.

Matter of opinion typically like many things.

What really actually ends up in landfill, more often does not really need to be discussed.

I wouldn’t call it religious, but you’d have to pry my CA18’s out of my cold dead hands.
