tube fanatic Posted November 5, 2017 Share Posted November 5, 2017 The 6W6 was originally registered by Hytron in 1939 for use in the audio output stage of car radios. It enjoyed a very long and successful life until it was ultimately replaced by the electrically identical 6DG6. It is also one of the nicest sounding audio tubes I've ever heard. Power output of these amps is approx. 1.3W which is more than enough to allow very loud levels to be achieved with most Klipsch speakers. They are particularly well suited to systems which are set up in rooms which are not terribly large, or in near-field applications. One of the local guys has described the sound as being "smooth as glass" by which he was describing a very smooth midrange and top end. And, as is evident with the 320 Hz square wave shown below, the bottom end is very potent (and also extemely tight and well controlled). The "ear bleed" filter across the input allows tailoring the high frequency response to individual taste. The amps run very cool and can be played all day, every day, without breaking a sweat. Tube longevity should be extremely long due to the conservative operating parameters. Should you decide to build a pair, keep in mind that THESE AMPS OPERATE ON VOLTAGES WHICH CAN KILL YOU! DO NOT ATTEMPT BUILDING THEM IF YOU LACK THE EXPERIENCE TO WORK WITH SUCH VOLTAGES IN A SAFE MANNER. The schematic is attached as a PDF between the first two pictures. Feel free to post any questions and I'll try to answer them as quickly as possible. Maynard Little Bruiser 3.pdf 1 Quote Link to comment Share on other sites More sharing options...
Schu Posted November 6, 2017 Share Posted November 6, 2017 I am very definitely intrigued... no electrical abilities though. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted November 6, 2017 Share Posted November 6, 2017 A nice pair of mono amp sounds like a great setup. Nearfield or a smaller room would work well. Quote Link to comment Share on other sites More sharing options...

Attached is a separate link to make it easier. These amps are about as simple a design as I can come up with. If constructed with reasonable care they will give more than a taste of just how wonderful single ended tube amplification can be with Klipsch speakers. And, if wiring is routed appropriately, they should be dead silent as well. Maynard Little Bruiser 3.pdf Quote Link to comment Share on other sites More sharing options...
gfxmla Posted November 6, 2017 Share Posted November 6, 2017 Nice...been wanting a pair of Monoblocs. This might be the project for me.Best regards-Geoff.Sent from my SM-G955U using Tapatalk Quote Link to comment Share on other sites More sharing options...
