Ｈｉ，Ｅｖｅｒｙｏｎｅ，
Ｉ　ａｍ　ａ　Ｆｉｎａｌ　Ｙｅａｒ　Ｓｔｕｄｅｎｔ　ｈａｖｉｎｇ　ａ　ｐｒｏｊｅｃｔ　ｏｆ　ｐｏｗｅｒ　ａｍｐｌｉｆｉｅｒ　Ｃｌａｓｓ　Ｂ，　ｎａｍｅｄ　Ｂｌａｍｅｌｅｓｓ　by Dougles self. I new to the LTSpice and now i requested to use the LTSpice Software to simulate the circuit. but unfortunately there did not have the Model Transistor BC 550 ,BC 560 , MJE15030, BD 139, MJE 15031.. all these types of transistor. BY simulating, i using the model in the LTspice Lib given which is nearly to the expected Vceo and Ic that I need.
I found this
More LTSpice models

and I followed the instruction to import but still cant work it out.
Could anyone give me some advice on how to do it.

Further more, I having the problem to simulate out the DC graph, AC graph and transient graph for the Class B Blameless Amplifier.

Hi nicholas1113
I’m not an expert on LTspice, so I can’t help you.

Maybe you should ask your questions in the software-tools forum.
Hopefully you’ll get an answer.

Cheers
