Features:

The Export version use the piano lacquer transformer cover that show it very high range.
The Export version use the Special Tailor-Made tube socket for the 805, so, make the tubes very good connect and strong, tubes get long life and have nice sound.
Hand welding point to point, the main circuit adopts shed welding
Two wide frequency high-end EI type single-ended output transformers with high-end special technology and high-quality broadband response made of Z11 iron core to get the sweet sound.
High-voltage power supply and filament power supply independently use large high-efficiency toroidal, high-power power transformers with Z11 cores and special materials with sweet voice.
High voltage and low voltage dual power transformer, double insurance design, lightning protection and short circuit protection and electronic tube insurance are adopted to prevent the electronic tube from burning the transformer. Level meter and bias meter switching use. Blu ray dual meter design, true full balance input and pure rear stage independent input.
The whole machine is designed with aluminium alloy casing. It adopts imported materials and is tested and inspected in strict accordance with European standards.
The front stage uses one 12AX7(ECC83)(Brand JJ) and two 6SN7 vacuum tubes; the driving part uses two 300B electronic tubes to amplify the rear stage.
The front stage uses a 274B(fishhook style) for rectification
The rear stage uses two 805A vacuum tubes for class A single-ended power amplification
Five groups of signal input A, B, C, (D) BALANCE, E (PREIN) This machine is specially equipped with balanced input function and pure rear function

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 music like Symphony, jazz.
