For Sale:
O2 Amp (built by myself) 1x/2.5x Gain Free Shipping and Paypal

Will Ship To: CONUS

It is kind of hard for me to part with this, but I am selling the O2 amp I built because I simply haven't used it in awhile.  All parts are based on the original recommended bill of materials by the designer.  I have set this amp to 1x and 2.5x gain to drive efficient headphones (Audio-Technica/Denon/IEMs/etc).  The reccomended batteries are installed and work properly.  The AC adapter is also included and is the exact one recommended for use with this amp.  I tested the AC adaptor with a multimeter to make sure it is still working, and it is fine.  The gain resistors can be popped out and replaced with higher gain resistors without soldering (I installed the sockets as recommended by creator).  I am not a terrible DIYer and have built and sold a B22 without problems, so I would expect this amp to continue working fine.  The front panel is made of black perspex and perfectly matches the power and gain buttons.  Please let me know if you have any further questions.

 

CONUS Shipping and Paypal fees are on me.

 

Sold!
