A 300B or a 2A3 tube drives an 805 tube for 40 watts of clean SET power. These well constructed and chunky mono blocks weight 27 kg a piece and are equipped with an independent power transformer . The front panel features volume control and blue power indicator light.. On the right side panel is an input if the mono block is to be used as a power amp along with a switch to use the mono block as a “straight in” power amplifier. As in most of Ming Da’s products high quality components such as gold plated RCA-inputs, hand crafted transformers and Alp potentiometers are used to create a long lasting product with outstanding sonic qualities in this price class. The amplifier is robust enough to drive Hi-Fi speakers with a sensitivity of more than 83db and a power range of between 100 to 300Watt.
