Radio constructors '' Tonar-1 '', '' Tonar-2 '', '' Tonar-3 ''.

Radio and electrical constructors, sets.Power suppliesRadio constructors "Tonar-1", "Tonar-2", "Tonar-3" have been produced since 1984. From all three radio constructors, you can independently assemble a high-quality audio amplifier for a home radio complex. The set "Tonar-1" allows you to make a power amplifier from a set of parts and assemblies. From the '' Tonar-2 '' set, you can assemble a pre-amplifier with a tone block. From the `` Tonar-3 '' set, a power supply unit with a housing for accommodating all the amplifier parts. The main technical characteristics of the radio designer "Tonar-1": rated output power at a load of 4 Ohm - 10 W; nominal frequency range, with uneven frequency response no more than ± 1.5 dB - 20 ... 30,000 Hz; harmonic distortion no more than 2%; nominal input voltage 0.25 V; maximum current consumption at a supply voltage of ± 18 V - 1.5 A. Radioconstructor "Tonar-2": nominal frequency range 30 ... 20,000 Hz; rated input voltage 40 and 250 mV; rated output voltage 0.25 V; tone control limits ± 8 dB; harmonic distortion 0.5%; current consumption 50 mA. Bipolar power supply unit and case `` Tonar-3 '' (described in accessories). The power supply unit provides unregulated output voltages of +18 and -18 V, which are required to power a power amplifier and a pre-amplifier with a tone block. The dimensions of the metal case of the set are 300x260x130 mm. In the case, in addition to the power supply, it is possible to install 2 power amplifiers and 2 pre-amplifiers with tone blocks on the chassis, that is, a complete set of units for a full stereo amplifier.
