Former Soviet triode GM70

Equipped with the former Soviet GM70 with Pp=125 W. With a plate voltage of 1,050 V, 30 W+30 W (4 Ω) and 20 W+20 W (8 Ω) output, it can drive low efficiency speakers. *Two models with graaphite plate and copper plate.

Two-stage configuration with C3g

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 input.
