Last OTS Stratojammer (9V)

thingiverse

15 Feb 2020 EDIT: If you're making these, please use hot glue and threadlocker to secure the screws and headphone jack, respectively. I redesigned the faceplace and case to allow hot glue over the screws and a recessed headphone jack nut. Also, make sure you're summing the amplifier outputs into the output jack. Otherwise you're leaving half the volume behind. ___________________ This a very specific headphone amp for 10 ohm, low freq response, mono headphones. If you’re not familiar with the term “stratojammer” you can still use the 9V holder! Feel free to make as many of these as you want. No secret family recipe or anything. I charge $50 assembled.
