Trimodal amplifier schematic

princesa · 22nd January 2009, 04:42 PM

Hi this is Sofia. I am 22 and I am a last-year student @ ICAI, which is one of the best institutes of technology in my country.
The thing is that I am working on a proyect in order to establish comparisons between different amplifier and also developing distortion methods.

I just wanted to know if you could help me find the Spice Schematics for the Douglas Self's Trimodal amplifier... I just can't seem to find it anywhere and I am pretty sure it would help me save lots of time. Right now I am welding the connections of the real amplifier to test it but I guess it could be interesting if I could be able to compare it with the simulations.

I found in this post the pdf schematic but I don't know how to make it work with Orcad.. so I'd be really thankful if someone could help me.

Thanks for your time and patience:

Sofia

Sofia ,you would have to input (draw) the whole schematic into pspice, I do not think theres any way you can make a pdf file work in pspice, it doesnt take much time anyway. I doubt anyone here has simmed that amp and most of us dont all use the same simulation software.

BTW welcome to Diyaudio, I see you new here. For spice related help you could visit the spice simulation thread although most of the information is around the ltspice simulation software.
