MUZISHARE R100 300B push 845 211 805 Single-ended Class A HiFi tube Amplifier Balance & Phono output
All items ONE-YEAR WARRANTY !!!
We can Declare the Value of the Order as Customer's Remark!!!
1. Handmade, the main circuit is scaffolded
2. Two high-end special process and high-quality wide-frequency high-quality EI single-ended output transformer made of Z11 core
3. High-voltage power supply and filament power supply independently use two Z11 iron cores and high-power power transformers with special materials
4. The front stage uses two 12AX7 and 6SN7 vacuum tubes; the push part uses two 300B tubes to directly couple to the latter stage.
5. The second stage uses two 805 goods 845 or 211 vacuum tubes for Class A single-ended power amplification.
6. Six groups of signal input: (PHONO, Line1, Line2, line3, line4, balance, pre in), this machine is specially added with balanced input function and pure post-level function.
7. Boot high voltage delay is very silent delay 30 seconds
8. Select Japanese ALPS high-end potentiometer
9. Easy to install plug-in vacuum tube cover
10. Peripheral power tube bias current adjustment function and power output level meter sensitivity selection file
