Willsenton R800i 300B 845 Tube Single-Ended Class A Integrated & Power Amplifier Balanced XLR Input

Main Highlights

Hand welding point to point, the main circuit adopts shed welding
Two high-end EI type single-ended output transformers with high-end special technology and high-quality broadband response made of Z11 iron core.High-voltage power supply and filament power supply independently use high-efficiency toroidal, high-power power transformers with Z11 cores and special materials.
Power-on high-voltage delay and mute delay function (about 30 seconds),Use Japanese ALPS high-end potentiometer
The 845 tubes can NOT work on a 805 R-800i amplifier, the 805 tubes can NOT work on a 845 R-800i amplifier. They are completely different amplifiers.
What is difference between 845 and 805 tubes? Usually, the 845 tubes have a smooth sound, it is good at human voice, very nice sound, but the power is not too high, so, 845 fits the speakers are high efficiency. 805 tubes have a high power, so, it work well with most of speakers(but please don't use 805 at a pair of very high efficiency speakers), and 805 is good at large dynamic musics like Symphony, jazz.
