Product Information 

Introducing the new deHavilland Ios Stereo 845 single ended directly heated triode amplifier.  The deHavilland Ios delivers the superb sound quality of the highly acclaimed Aries 845-G  monoblocks and features 25 watts RMS  power output per channel into  8 ohms. The deHavilland Ios is a 100% pure Class A single ended triode  zero negative feedback vacuum tube amplifier. The Type 845 directly heated triode vacuum tube is justly famous for its sweet tone and authoritative presentation of music. The tube complement combined with innovative circuitry maintains the right combination of pace, rhythm, and timing. The deHavilland Stereo 845  is designed to drive medium, as well as high efficiency speakers. The dynamic presentation is characteristic of an amplifier many times greater than its rated output.

There is no question of reliability with only three tubes per channel,  diagnosing any tube problems that might occur after time is relatively simple. With the on board meter, checking and resetting bias for optimum performance  is a real snap. Quality, Value, and Performance, by deHavilland, "Hand made in California with a passion for sound since 1997"
