This is the highest quality DIY kit using quality parts with a detailed builders guide. First time builders have been successful but you should be able to read schematics, layouts and solder in order to assemble the board and wire up the amplifier using your choice of transformers and tubes. We recommend that you be familiar with high voltage tube amp construction, safety and troubleshooting and have some build experience.
Save yourself a lot of time finding and sourcing the parts, and get a professional build as a result.
