is a workshop dedicated to design and manufacture valve amplifiers. We have had more than ten years experiences on this field and had great achievements on Power Amps especially High Power Output Single-End Valve Amps. Please refer to below for a few products we developed recently.
1) 100W 7092 Direct Heater Single End Amplifier.
Designed by RCA, 7092 is still manufactured in China and widely used in various industries. This direct heater tube has astonishing 800W plate dissipation and quite linear operation. We are using two stages-6SN7 direct couple 300B to drive 7092, the sound come out quite good. We also installed a special designed safety switch to protect circuits from surge voltage and currents to en-long the working life of tubes and to improve safety and stability of the amp.
2) 85W 833 Direct Heater Single End Amp.
With 300W plate dissipation, 833 (China’s FU-33) has plenty of inventory and wide usage in China. We are using 5687 direct couple 300B to drive it. 100W output make it easy to work with modern low-sensitivity speaker system. The Surge-Proof safety switch had been also implemented to protect the safety and stability.
3) 40W 805/845/211 Direct Heater Single End Amps.
We are using 6SN7 direct couple 300B to drive the DHT 805/845/211 in this amp. Besides the safety switch system, this combined amp has a few modern functions: 1) 80 Steps Remote Volume Control; 2) VFD Display; 3) USB I/O and channel decoding and sampling IC to couple with emerging HI-Fi Audio Resource like MP3 and IPod.
4) Preamp.
1) 12AU7 Direct Coupled;
2) 80 Steps Remote Volume Control and VFD Display;
3) USB I/O and channel decoding and sampling IC to couple with emerging HI-Fi Audio Resource like MP3 and IPod.
We have abundant experiences on designing and manufacturing valve amps. We are looking for partners around world to work together to develop and grow in the market.
