HF High Power AM Transmitter Project For Sale

[Switzer, Emil]

I have the following items for sale. The plan was to build an AM modulated
amplifier using a pair of 813's plate modulated by another pair of 813's
connected as triodes.

Most of the mechanical work on the main amplifier is done.

This package is too large and too heavy to ship. I can deliver to Dayton
this year or am willing to meet someone within 200 miles of Ft Wayne, IN.

I am asking $375 for the entire package. If anyone is interested contact me
and I can email some photos of the individual components.

sides
