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.","brand":"INDEPENDENTLY PUBLISHED","offers":[{"title":"New","offer_id":67611578106146,"sku":"9798711423324-new","price":22.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/4755\/5618\/files\/9798711423324.jpg?v=1793072137","url":"https:\/\/www.albakireads.com\/products\/audio-amplifiers-tube-preamp-building-simple-circuits-yourself-9798711423324-new","provider":"AlbakiReads","version":"1.0","type":"link"}
