805 Triode single ended mono blocks

Designed in Leicester by David Shaw, founder of Icon Audio the 805 valve is capable of making golden sublime music. 

A sister valve to the RCA 845, the 805 is capable of greater power output, but is extremely demanding of the driver stage. They have used  4 6SN7s and 2A3 power valve to do this.

For some people only a large triode valve like the 805 can give the golden warm tone which is so pleasing, with its feeling of air and space and sense of realism. But many 805 amplifiers are low powered. The MB805 is designed to deliver 50 watts. More than enough to play large orchestral works and modern music.
