alamo 5W header Download the funky Alamo Challenger.

The Alamo amp is a great little Class A 5 Watt all tube amp with some really different technology.

EZ to build with a single 6L6, a 12AX7 and a 5Y3 tube. The challenger has the Power tube Direct coupled to the 12AX7.

This makes the amp have almost unlimited frequency response - a neat trick.

The circuit appears to be set up for real good highs and a somewhat scooped midrange, pretty much the opposite of the Supro 5W Download project.

Fun to build and real different - a great download project.
