High-End GM70 Mono Block Valve Tube Amplifier Split Single-ended Class A ()

Description GM70 Mono Block. The amp sounds VERY powerful, with strong bass, pure trebles, scary close mids, deep 3-d soundstage - all I wish for and more. All are 100% handmade with the best materials (say no to China) The frame is made of monolithic aluminum with high precision, very strong I hope there is nothing that can fail, even after 30 years of service. The my choice for this project is the GM70 because in a direct comparison with the 845, the GM70 have the same sound quality. The main advantage of the GM70 is the high voltage gain so it is possible to use a simple one stage driver stage. us have used a load of about 10Kohm to get a good damping factor (less than 2ohm) and an anode voltage of 1050V to get a power about 48-50w/ 1 channel Maximum output power: 50W * 2 (Type A) THD, 1% 1kHz response Frequency response 10Hz 35kHz （ Rat 87dB S / N ratio (weighted A) Input impedance 100kΩ Impedance Output: 4Ω, 8Ω, 16Ω Power co
