Esoter Evoque Pure Amplifier

[Stee]

this is a project based on my
"One to Hundered Rule"
a Quasi Zero Feedback solution
compared with a gain of 26dB natural
is set to do a gain 40dB
however, in order to correct the open loop

The first schematic look like a wikipedia picture while the second one
has the same tipography as Rod Elliott s ESP site....

Anyway , there will be uncontrolable DC output offset , largely
varying with temperature and quiescent current...

What's wrong with feedback? Oh and there is feed back in this amp you just make it at vas not on the output so you get the second harmonic of the outputs and other harmonics too.

Just why though?

I think it is "output exclusive" GNFB. You can test and service amps with this arrangement when the output stage is removed. Agree, you tend to get a pretty rough spread of crossover distortion harmonics this way.

I'm not sure it's a good idea to keep posting up rode's copyright material with just a few mods. If it's identifiably copyright, it's sending the wrong message to our membership and readers.
