Download or read book Audio Amplifiers with Tube Preamp written by Klaus Röbenack and published by Independently Published. This book was released on 2021-02-19 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amplifiers equipped entirely with tubes require a great deal of circuitry and mechanical effort. A conceptually and technically interesting compromise is the combination of a tube preamplifier with a transistorized or integrated power amplifier. This approach, which has also been implemented in quite a few commercial devices, is the focus of this book. The described tube preamplifiers can of course easily be combined with other amplifiers.
