Vacuum tube type stereo power amplifier with direct heating triode GM70. Plate voltage 1,050V, output 30W+30W. No-feedback technology creates a three-dimensional effect and a sense of presence, and expresses a clear sound.
Soviet triode GM70
It is equipped with the former Soviet GM70 with Pp=125W. With a plate voltage of 1,050V, 30W+30W (4 ohm) and 20W+20W (8 ohm) output, it can drive low efficiency speakers.
Two-stage configuration with C3g
It is equipped with the ultra-reliable C3g, developed by Deutsche Telekom for telephone repeaters. The thin grid lines and large distance between electrodes enable high linearity amplification. The C3g is soldered directly onto the board to reduce noise at the contact point.
Large Output Transformers
The large output transformer developed exclusively for this product is installed. Multi-layer sandwich winding drives both small and large signals over a wide bandwidth. Low winding resistance and drive capability, so it has a damping factor of more than 5 despite being a no-feedback amplifier.
Normal, Dual, Bridge Mode Switching
One more unit can be used as a bi-amp to drive the high and low frequencies. In bridge mode, the output can be driven by 1.5 to 2 times.
*Except in normal mode, it is valid for Lch/XLR inpu
