Dear friends.
I build this vintage quasi amplifier in ltspice. I just start using ltspice a few days ago so i wanted to know that how to simulate it. Need advice and tips.
Thanks in advance.

Your scheme is very strange. Look at how to do it. It is necessary to add temperature stabilization.
Thank you sir i have seen your schematic it looks great.
But some components are missing in ltspice like in4148c or 2sc3503 or c5200k how can i get them all in my ltspice to get full simulation.
Actually, 2N3904 are not good enough for a supply voltage that high, but LTC spice does not simulate Collector avalanche voltage.
Yess thats looks pretty nice and very simply schematic & also very easy to build.
I like it.
Many thanks steveu sir.
I will build it soon 🙂
You were properly guided by Mr. Steveu. I'd like to provide you with a schematic that might be useful in building the amplifier of your dreams.
Zohaib Ahmad, look at this option. There are even fewer distortions. The supply voltage should not be increased.

Good work printnik sir you make my amp more stable.👍🏻
You know very well about buiding amps in ltspice.
Many thanks all of you for giving me your rare time.
Facing problem in importing cordell models in to the ltspice.
I have import models into ltspice library but they are not showing in ltspice.

@Zohaib Ahmad re deleted file.

Mooly sir i am trying to importing bd 139 bd140 and others ltspice models in to ltspice library but they are not showing.
Any easy way to import cordell model to ltspice library?

Here is a diagram with BD139, BD140. You can take models from Cordell-Models.txt and insert them in text form into the diagram. You can put this file in the same place as the .asc file and link to it : .inc Cordell-Models.txt .
Sorry sir but it is not working i have tried many ways to put cordell model to lt spice but nothing is showing in ltspice.
Change the directive from a comment to spice directive (right click each one).
You need to add a directive to include the name of your text file.
The models you use must be exactly as written in the test file. So RED for the LED and 2N5551C and so on.
I find it much easier to paste a model file into the C drive root directory and just add a single directive on each sim.
