45 Watt Single Ended Triode Monoblock Amplifier
" This amp sounded extremely sweet, and yet VERY powerful." Dick Olsher ...more
The deHavilland GM70-A is a 45 Watt 100% pure Class A single-ended triode zero negative feedback amplifier. The GM70-A directly heated triode vacuum tube is the largest output triode available in audio today. The sound is sweet, detailed, and stunningly dynamic. The 300B combined with the GM70-A with innovative circuitry maintains the right combination of space, sweetness, and speed. The dynamic presentation is convincingly that of an amplifier many times greater than it's rated power output.
Historically, SE amplifiers have been limited in power, largely under 15 watts. Most listeners have had to employ horn loaded speakers. The deHavilland GM70 amplifier, with 45 Watts, will perform beautifully with your favorite loudspeakers whether they be medium efficiency dynamic or high efficiency horn type loudspeakers.
And think about reliability, with only three tubes per chassis, diagnosing any tube problems that might occur after time relatively simple Quality, Value, and Performance, by deHavilland , hand built in California with a passion for sound.
