The book provides value to everyone at any level. If you are new to building audio projects, you can build exactly what is documented with confidence that you will have working results. For those beginning to branch out on their own, the great tips and known designs provide invaluable reference points. For experienced builders, the compendium of design information in one spot will save time, lead to better results, and trigger new ideas you can bring to the next level. The book is worth having on your bookshelf. It will be relevant to tube amplifier audio design for a long time. I predict that years from now, it will be considered a somewhat legendary reference source, providing a unique contribution to the tube amp audio world.
