Highlights
This is a bare PCB for the Pocket Class A Headphone Amplifier. It is a custom designed SMT and through-hole 2-sided high quality FRP PCB. Dimensions are 57mm x 38mm z 1.6mm thick and designed to fit inside an Altoids type mint tin with room leftover for 2 9v batteries. The sound quality from this single-ended pure Class A amp is unbelievable. You can order the parts (BOM) yourself or through this shop.
Note that boards are now in premium ENIG gold finish with blue solder mask. Still the same price.

Reviews for this item
Item arrived securely packaged. It is quite well made, excellent quality. This is true of all of the purchases I've made from this company, and I've made several.
Good quality PCB, delivered quickly.
Not only are the PCBs amazing, the person who represents the company is too. I am still in contact with them figuring out my second and third amplifiers that I will build! Totally recommend, for the sound of the amps, and the awesomeness of XRKAudio
Great quality, although I wish there were other pcb colors! Used a reflow oven to solder SMD, and then hand soldered the rest. Very good instructions on building. Be sure to know the impedance of your headphones, as this will determine which components need to be procured.
