hello guys im trying to do a report about audio amplifiers that don't use opamps. only transistor which all parts can be simulated so I can calculate the input/output impedance, voltage gain and power effiecncy. do you have some schematic? i really need some help. plsss

 

Is this a school/colllege/workplace assignment?

for college report sir. do you have any?

 

If you do a bit of googling you should find several published schematics for hi-fi amplifiers, e.g dating from the 1970's onwards.

Is this for a circuits or other EE course? If so, I would expect that the idea is for you to write a report about a discrete amplifier design that YOU designed.

 

Here you are, a nice one I had to repair the other day - Denon 435R. The power amp is all discrete.
