12AT7 Regen: Catching Kuwait (9K2KO)
In this video, we put the 12AT7 regenerative receiver to the ultimate test and manage to pull in a signal all the way from Kuwait (9K2KO). It’s a great demonstration of what these simple vacuum tube circuits are capable of when the conditions are right! If you're interested in how this specific receiver was built, check out the technical breakdown and the full build series below.
