GM70

GM is a well known Soviet era tube, that belongs to DHT kingdom, and reigns supreme as one of the most powerful, reliable, well behaving , long life, musically engaging tube. Frankly, I haven't yet found a 211, 805 or 845 that could hold a candle to the GM70.

Downsides?  It is hard to implement (my problem, not yours) and it is HOT. Very hot. That's why I never use more than one tube per chassis.

Monoblock amps based on GM70 are very attractive proposition. Compared to say , very popular 300B tube, GM70 has 3 x the power, , better bass control, better sounstage, and similar mids and highs. GM70 is cheaper tube, lives longer and has a fun factor of 10.

To implement this tube, we use custom designed power transformer, custom designed output transformer and custom designed filiament transformer for heaters. This tube needs 10 times the heating of 300B.

The resulting sound, on speakers of say no less than 90 dB/W/m is phenomenally dynamic, rhytmic, spacious and colorful. This amp brings back the joy of music and the smile on the face.

SOME MAIN FEATURES

Manually controlled bias, bias meter for real time verification, ultra short signal paths, no silicon in the circuit, no interstage transformers, three separate power transformers, with total of 600 VA of power, idle consumption 180 Watts per channel, 4 and 8 ohm outputs, one or two SE inputs RCA, stepped resistor ladder volume control with very precise 48 steps. Dimensions H = 30 (with the tube) , W = 43, D = 52.

On the rack shelf it needs 40 cm total clearance and 60 cm total depth and that includes cables.
