The JBAA tube amplifier can use a 12AX7, 12AU7, ECC82, ECC83, 5751, 12SL7 or 6SL7 in the driver position while 6V6, 6AQ5, 6005, 6Y6G, EL84, 6BQ5, 6F5P, 6P15P-EB, 6Y6GA, 6K6, 6W6, 6GV8, 6BM8, ECL82 or ECL85 can be used for the output tubes. The schematic is similar to the PoddWatt design and able to use a huge variety of tubes. High Fidelity Tube Junk Box Audio Amplifier - 10 November 2019 NEWīruce Heran outlines the design and construction of a High Fidelity Tube Junk Box Audio Amplifier (JBAA). For more DIY projects, use the navigation menu on the left hand side of the page. A great project after all, and i'm sure i'll get an other one in the near future to run them as monoblocks.These are some of our featured DIY audio projects. I now use it with 89dB sensitive diy speakers, and for normal listening volumes that +/- 8W is enough (altough i plan to build higher sensitive speakers for it). But the sound is open and detailed and the harmonic distortion that is inherent on this topology is never an issue, it's rather subtile and only an advantage. I also use a commercial tube amp (Prima Luna Prologue 4) that is not better but it has a slightly different sound (due to the different topology). On sound i can absolutly not complain, it's a great sounding amplifier that does not sound worse as the class A amps i heared in the past (Sugden, Pass Labs, Musical Fidelity) that costed way more as far as i can remember. And the person who did the soldering and assembly for me did a great job so it look very good on the inside also. But i would clear that out even if it's a very minor issue. But with a little experience and logic thinking it's easy resolved. Also the biasing process is not fully clear explained. Twisting leads like explained in the guide is not that good, it's better to bind them toghetter as example (and so we did). Parts are all high quality, and nothing mssing (i had parts to much i think).īuilding it was relative easy (a friend who has experience with building electronics did most of the work, while i was assisting her), but some details in the guide are not clear for the 1.8 version i have or not the best practice. The case that came direct from the supplier in Italy took a bit longer, but still reasonable.
