"Frankly, you would be crazy or foolish (take your pick) to spend more money on a SE power amplifier." Dick Olsher, enjoythemusic.com
"deHavilland Electronics...the room we revisited the most. Sound to die for." John Zurek, Positive Feedback RMAF 2008 Show Report
Product Information
Aries 845-G
Introducing the new deHavilland Aries 845-G Single Ended Directly Heated Triode amplifier. The Aries 845-G delivers the superb sound quality of the original Aries-845 and now produces 36 watts rms into 4 ohms, and 30 watts rms into 8 ohms .The deHavilland Aries 845-G 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 compliment combined with innovative circuitry maintains the right combination of space, speed, and pace. The deHavilland Aries 845-G is designed to drive medium, as well as high efficiency speakers. The dynamic presentation is convincingly of an amplifier many times greater than it's rated output

deHavilland GM70
We are very proud to introduce the new deHavilland GM70. We have surpassed our our design goals and now offer 60 watts of purist design Class A sound from one single output tube. The deHavilland GM70 maintains all the virtues and more of our highly acclaimed deHavilland Aries 845-G. With double the power output we achieve lower distortion at normal listening levels and greater headroom that can be imagined for a SET design. To quote Dick Olsher, Senior Editor, for EnjoyTheMusic.com, "There's a new heavyweight contender in the high-power triode class. Neither a 211 nor an 845 can hold a candle to the Russian tank tube- the Ulyanov GM-70." Never before has a single ended triode amplifier been offered to the music lover with such performance.
The deHavilland GM-70 is a 100% pure class A single-ended triode zero negative feedback amplifier. The GM-70 directly heated triode vacuum tube is the largest output triode available in audio today. The sound is sweet, detailed, and stunningly dynamic. The 6AU5 combined with the Ulyanov GM-70 and innovative circuitry, maintains the right combination of space, sweetness, and speed.
The deHavilland GM-70 amplifier produces 60 watts, and is designed to drive medium, as well as high efficiency speakers. The dynamic presentation is convincingly that of an amplifier many times greater than it's rated power output.

power output : 60 watts rms into 8 ohms
output class : Class A bandwidth : 20-35kHz
power triode : Ulyanov GM-70
driver tube : Type 6AU5

deHavilland Ios Stereo 845 25 Watts Per Channel SET Stereo Amplifier
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 compliment 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.

deHavilland Mercury Preamplifier
Product Information
We are proud to bring our top of the line Mercury vacuum tube line stage preamplifier to production.. It features the Type 85 six pin triode vacuum tube, and all vacuum tube rectification, using the 5AW4 octal tube rectifier. The Mercury preamplifier is the next step beyond the highly acclaimed UltraVerve preamplifier. We designed around the beautiful Type 85 triode vacuum tube because of, quite simply, its ability to touch the ineffable.
We developed this line stage to complement our single ended triode amplifiers. One of the things we achieved was to design a preamp that did not damage the dynamic quality of the music. The Mercury line stage is a true zero negative feedback Class A design. The tube complement coupled with tube rectification produces a huge, full-bodied soundstage and an angelically sweet and dynamic midrange. This preamp is just a joy to listen through.
The Mercury preamplifier features 100% hand wired point-to-point circuitry in the audio as well as the power supply circuit. The front panel is heavy duty Mercedes Silver powder coat with Steel Gray powder coat chassis. It features a soft start turn on circuit for gentle startup. The design places very little stress on the tube compliment. This assures extremely long service and sonic life of the tubes. Quality, Value, and Performance, by deHavilland, "Hand made in California with a passion for sound since 1997"
according to Kara:
The vacuum tubes we employ give you what in "Tube Lore" is described as "BIG TONE", something you just can't get with nine pin miniature tubes found in most preamps. 12AX7’s or 6922’s just can't get there. While many companies say that the simplest circuit is the best, they don’t practice what they preach -- they have miles of circuitry and solid state regulation everywhere. Our R&D shows that regulated power supplies can ruin the dynamics and imaging, just like too much feedback does. We spend more time and money on our filtering and use big, strong 5U4 and 5AW4 tube rectifiers, because they provide super dynamics. Furthermore, all of our power supply and audio circuit wiring is point to point, using the best wire available and the best dielectric known to man -- air. And while others may dress their equipment up with fancy gold or chrome plating and exotic woods that offer little or no sonic improvement, we prefer to use premium components and provide you, the listener with affordable, high quality equipment. Our gear is literally overbuilt to last a lifetime! At deHavilland, we are serious when we say that we want more listeners to be able to experience the beauty of single-ended vacuum tube sound, making this type of pre amplifier available to a much wider range of listeners -- that's our story.
Grid caps, custommade on our CNC vertical mill, feature pure billet copper spring loaded contact. Please note the grid caps are completely safe and do not carry any DC voltage.
