New versionin 2021: MUZISHARE R100 will be an upgraded version with a new price;
MUZISHARE R100 upgraded version,
1. The front tube 12AX7 is replaced by Czech JJ ECC83, 6SN7 is replaced by Russian EH 6SN7, and the other 5 large tubes are specially customized black core carbon spray screens, of which 300B is a customized re-engraved western power tube.
2. The internal circuit Optimized and upgraded the choke to a fully shielded Z11 iron core single crystal copper choke,
3. Add infrared remote control function
MUZISHARE R100 have 3 version : 845/211/805 , the exterior of amplifier are same between these 3 different version ,but each version is definitive, it can NOT exchange the power tube between these 3 differents version
Features: 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
