In this video i assemble the 6j1 tube preamp/headphond amplifier.

A few curve balls and problems along the way but nothing that i couldn't figure out and share with you how to avoid.

There is an extra diode that i have to trace the board to find where it belongs and the polarity it belongs in. jump to 5:30 to see this

I share the location and orientation of this diode so that you don't burn up your circut.

Ebay has lots of these kits available cheapish so grab one and give it a try!
