Directions Assembly and use instructions included (English language not guaranteed) Manufacturer's Description A Pristine, Compact Sound Amplifier You Build Yourself The HA-S is a Nutube-equipped DIY Headphone amp kit that will let you enjoy the highest quality audio anywhere. No soldering is required, so even if you are new to the world of DIY, you will be able to assemble the HA-S to add a warm, analogue tube-driven signal boost to any sound source in no time! Build your own Headphone amplifier This DIY HA-S kit allows you to build your very own Headphone amplifier in an easy and fun way, without any soldering needed. Not only that, it provides the authentic vacuum tube sound that audiophiles know and love. Built-in Nutube Nutube is a new and revolutionary fully analogue vacuum tube developed by KORG INC. The same as a conventional vacuum tube, generating the response and same rich harmonic characteristics of conventional vacuum tubes in a more compact, stable and energy-efficient way. The transparent case of the HA-S delivers a glimpse into this technology; allowing the glow of the tube to be visible at all times.The filament of the Nutube is powered by a DC to DC converter, which consumes less electric current and thus allows for a longer battery life than other vacuum tube equipped amplifiers. The design is so efficient that the HA-S can drive the Nutube with a line voltage of 26 V using only two A4 batteries, for a rich and authentic vacuum tube sound. Sound possibilities The HA-S has a special NFB (Negative Feedback) switch, that allows you to choose from a high fidelity clean and pristine sound, or a warmer, more harmonically rich sound as expected from a vacuum tube. For further sound modification, we have included two OP amp options for the output: the premium audio oriented "MUSES01" and the industry standard โNJM4580โ, both from JRC. These can be easily replaced so even the most purist audiophiles will be able to customize and adapt the sound of their HA-S to heir heartโs content. For advanced users who want to customize their amplifier even more, the circuit diagrams are readily available, making it really easy to change discrete components and make your own and unique headphone amp matching your desired tone and performance -, the possibilities are endless!

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days โ so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
