I always make Rodd Elliot's P3A amplifier for friends, a simple, straightforward amplifier with excellent features, but, like most transistor equipment, it suffered (to my liking) from a treble handling that did not satisfy me. . While I'm not one of those audiophiles who can tell if you bought the speaker cable from Radio Nakama or Todo Vision, I am the type who has to "like" how it sounds. Lo and behold, some time ago I had experimented with an amplifier with a Mosfet output:
Amplificador 50W Mosfet
and it sounded excellent, the highs clear and free (excuse the marketing expression, but I can't think of another way to translate a listening sensation into words). From that moment the question kept turning over me... can something like this be achieved with transistors...? I started with a simulation on a P3A (sorry Rodd...):

Seeing that the thing worked, I began to make a real experimental platelet. The difference is in the output, since I didn't get original PNPs I made a quasi-complementary output:

The listening impression is excellent, finally treble as I like it in a transistor unit, I think the Miller effect.......
