hi guys,

can someone tell me the difference between the f4 and ba2 output stage, if they both have the same number of output transistor at the same bias?

or what is the difference between the capacitor arrangement responsible for push-pull driving?

i guess the sound difference is very subtle if unheardable, but what is the advantage of using one over the other. One(f4) is symetrical with 220 UF caps and the other(BA) has a coupling 10uF cap with a 1000uF to ensure a push-pull.

i looked a bit for the answer but it couldnt be found anywhere...

No. Just more versatile. In truth, the output stgae should be better, as you have dropped a stage and source of possible distortion. Every component takes a little bit of life with it, some more than others.

Both same, basically, as ZM said. Question is, how to get rid of it.

they're enough the same

to get rid of it ..... you need FE more glued to it .... in other words - FE with implemented biasing for output stage
