By fully exploiting the parts and expertise, we adopt a stable all-stage direct connection OCL pure complementary circuit. Moreover, by adopting a parallel push-pull circuit boasting high output and low distortion ratio, the total harmonic distortion rate, cross modulation distortion ratio, power band width from the small output to the high output also changes from 5 Hz to 40 kHz 0.1 We guarantee under% with sufficient margin.
A large-sized power transformer and a large capacity capacitor of 4 × 4, 700 μF are used for the power supply part.
Bass and treble are ± 15 dB at 3 dB step, ± 5 dB at 1 dB step of mid-range only, and Ideal curve is obtained, TTC (triple · tone control) of only Sansui is adopted.
The TTC amplifier uses low noise FET to ensure high input impedance in the first stage, and it is NF type of three stage direct connection, two stage direct connection circuit.
Checked, serviced and adjusted.
