HIFI SanKen1494/3858 Two channel Audio Power Amplifier Board Stereo 300W+300W
High fidelity power amplifier. The high-speed, low-noise audio tube is used as the input stage and
the boost stage, and the rear stage uses four pairs of 2SC3858/2SA1494 high-power tubes for
output current amplification. The line has the advantages of strong output power, good sound
quality, wide dynamic range, good transient response, etc., as well as delay and horn protection,
output midpoint protection, overload short circuit protection and so on!
The main parameters:
Peak power: 300W+300W
Frequency response: 20Hz ~ 20000Hz
Power supply voltage: AC dual 24V ~ 32V
(Note: the voltage should not exceed 40V. If it is over, burn it, it is your responsibility! Under the
condition of long-term high voltage and high temperature, a small instrument fan should be added
to assist the heat dissipation to ensure the long-term stable operation of the amplifier.)
Volume: length 230 × width 145 (including heat dissipation) × height 90mm (filter capacitor + heat
dissipation)
Net weight: about 1.05 kg
