Audio Amplifiers with Tube Preamp: Building Simple Circuits Yourself (Paperback)

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.
