ST70 Output Stage Schematic
in the above link you can click to zoom in or download it.
1) What are all the parts that comprise the "output stage"? For question number one here, I'm not looking for a comprehensive parts list. For me it would be easier if you could answer this question by refering to the attached schematic and use the red line in it.
2) what function do those parts in the output stage do? again, not a comprehensive write up just in general summary format
3) in the attached schematic did I draw my red line correctly? I'm trying to include within the red line only the parts that are considered as parts of the "output stage"
if I drew the red line correctly, the output stage only consists of the following; two EL34 valves, and three resistors (R8, R24 & R25). That's it?
just five parts? no capacitors nothing else is part of the output stage in this schematic?
So what does the output stage in this schematic require as inputs? In other words, what are the parameters of the audio signal immediately before they enter into the output stage? And what are the parameters of the audio signal at the exit point of the output stage?
I know I need to learn many more complex things but at this phase of my learning, I need to first learn the basics of the output stage expressed to me without any formulas and without any technical jargon (well maybe a little jargon, like I know voltage, ohms and capacitance, and amperage and audio signal, etcetera). And I know there are two output stage sections one for left and other for right.
