Erik Konka Headphone amp #1 is designed by well known estonian tube amp designer Erik Konka. He has built and designed numerious high end tube amps, preamps, DACs during years and now we finally started to co-operate to create reasonable cost, but very high end tube headphone amp that is easy to build, even by beginners.
All the parts are mounted on single PCB that is connected to metal sheet where power transformers and connectors are installed. This structrure makes Headphone amp #1 very easy to build but still exceptionally good looking, when mounted on wooden frame. Beginner can build it in one or two days and professional in one day, or even in one evening.
Power amp is designed with NOS 6AS7 / 6080 tubes without output transformer (OTL). This is the secret for very good sound quality: output transformers are difficult and expensive to design and manufacure. OTL makes amps huge if lots of power is needed, but with headphones, it is just best possible design choice.

For whom this kit is suitable?
For all of you (us) who loves high end audio gears and like to do something with your hands. UralTone kits are easy to build, so they are also great for beginners. This can be your first project or your project no 134 - it's always rewarding to use something that you have built by your own hands.
Kits are also great for those who like to have boutique quality but cannot pay the price of high-quality boutique pedals.
What kind of tools do you need to build this kits?
Pretty basic tools are enough but, especially if you are the beginner, please use a good soldering station and good quality solder. Making good joints with lousy soldering equipment is difficult. We have collected a tool kit from the tools we actually use every day. These are not that expensive but works great for building pedals and amps. You can find it here:
