The latest stereo production

  

  Hardcover book. Valuable book that mainly only explains production of tube amp in Nagaoka [tetsuotoko] teacher's book. It slightly explains an analog player, the speaker system, and how to make besides the tube amp. The number of books on the speaker making by oneself increases to the Nagaoka teacher after this and the book written only about the amplifier is not published.

  Because this book is a book to which it was written to have been published by about 40 years ago 1969 and now, prices might differ, and be now and corresponding difficult purchase and making the same parts. The spirit of Nagaoka [tetsuotoko] "Can may be the very cheap one be made?" is carried out here.
