The one valve kit is based on Armstrong's original design, which was popular to constructors through the mid 1920's and into the 1930's.

Easy assembly, for example no coils to wind - that has already been done for you! And  simple to follow instructions with both schematics and wiring diagrams!

You get a manual, all the parts including valve, sockets, jack plugs, tuning capacitors, coils, resistors, wire, nuts and bolts etc, and we even include  an earpiece.
