LE Amplifier Book

Hi to everyone.

We would like to inform everyone that the availability of the book  entitled "A High Performance Audio Power Amplifier Design and Analysis" is currently unavailable. We are looking ways for a local publisher to do a low volume production to cater to our needs. Given that a substantial request will be for the book, we will let you know.

Thank you for your interest in our designs and we hope to hear from you all successful builders.

Until then, stay tuned.

Series 2 Quasi

Here is the quasi-version of the Series 2 Audio Power Amplifier design. Its output transistors are both NPN-type. Successful builders commented that its performance with regards to the low frequencies is highly exceptional.
