The RS-100 & RS-100U line Amplifier Circuit consists of special selected Dual-Triode Tube 6CG7(General Electric/USA) by SRPP system to improve high-frequecy range of the sound, and can supply a strong signal of 52V to the power amplifier. For lighting the heater of 6CG7 tubes, DC current(12V) is applied to minimize the noise of heating, and additionally, 60V bias is applied to the heater to cancel the noise caused from the heater. Other features:
* Two Outputs: One is Variable(with Level Volume) and the other is fixed.
* Five inputs plus Direct input.
* REC OUT/REC MONITOR IN
* Muting 30 minutes after Power-On.
* Natural wood Side Panels.

To avoid compromising sound quality using the NFB type, one of the solutions adapted is to completely protect the sensitive CR type equalizer was to originally develop for RS-30EQ a high quality "Orient-Core" power transformer perfectly shielded to shut-down hum noise from the transformer perfectly.It is with the finest available high-end audio components to keep the deflection of the RIAA curve below +/-0.2%.
