hi-fi amplifier (1)
Best vintage stereo amplifier, vintage hifi stereo system, tube amplifier stereo, studied on vintageshifi.com, with their instructions, service manual, and for the most part the list of transistors and their equivalents to carry out a careful restoration. Come explore these some 120 pages devoted to these bestsellers of the hifi and take the time to browse the site. When it comes to reproducing and amplifying sound, some of our older stereo amplifiers have nothing to envy today′s audiophile devices. Their only problems are the resistance over time of their most sensitive components. It is for this reason that it is better to buy restored devices, and it is even preferable to choose a device of a certain level of the range from one of the best reputable manufacturers specialized in high fidelity. The extent of our hearing field has not changed (20-20.000 Hz). You can buy a vintage amplifier, but some devices! Yesterday like today everything is not advisable.
