Two colors are available: Black and Silver Willsenton R8 is an integrated Amplifier, it is a Power Amplifier too (there is a group Power amp input), it is a Headphones amp too.  One amplifier can used wiht tube EL34, KT88 or 6550, so, you can get 3 kinds of sound from different models tubes if you buy more 2 new sets of tube.  Triode and ultra-linear Switchable.    Normal we suggest customer choose the upgraded tubes version Features  • Pure hand-made, the whole...

Purchase tips: The appearance of 211.805A.845 is roughly the same. 300B pushes version 805. Special external high-pressure cap is available for players to replace the 805 tube to play, adding fun 3 types of circuit design are different Power tubes cannot replace each other, each has its own merits 845 tube version: 805 tube version: 845 Features:  Hand welding point to point, the main circuit adopts shed welding  Two high-end EI type single-ended output transformers with high-end...
