is this amplifier is working?
does it sounds good?


Audio Amplifier 90-100W with 2N3773

yes it will ...only think you need to do is to take care of the classical construction notes ...this is a very old circuit and since its a bootstrsap quasi without vilimiter its expected to play but not perfom stable under peaks or heavy loads especially 4ohms

Thank you sakis

How can i add vi limiter to it can you please guide me

[sakis]

VI limiters will perform beter in a classic complementary amplifier if a re getting in to the story of adding things in to the circuit then you may as well pick another more modern circuit

depents a lot also on the application ...if you built an amplifier like that for home use you might get away with it if you expect more then choose another circuit

hi shreya ,
how did ur simulation go. Neways this circuit will work but u can opt for better circuits . I have a collection of circuits that i have made and they work real well. Pm me if u need any thing.

The design is from the 1970's. I designed and built many similar amplifiers in the 70's.
As sakis said, this design will work okay into an 8 ohm load and at moderate audio levels. Don't push the amplifier too hard.
A newer design would be a better choice.
