Due to the time and space involved, I have decide not to convert this
beautiful transmitter.  It is an original owner unit built by Collins in
1869 in 1969.  All original documentation from the factory and installation
is included.  Very large 8 1/2 X 11 notebook with all pages in plastic

The Collins 820D-1 uses a pair of 5-500's modulated by a pair of the same.
The transmitter is solid state up to the final and modulators.

 Most users converted the transmitter to use 4-400's by simply changing the
filament transformers. I have the new transformer designed for this

The transmitter comes with a remote control panel for operation from the
operators position.  The transmitter is designed to be placed flush against
a wall.  Everything is serviced from the front. It is 23 inches deep, 41
inches wide and 69 inches tall.

Complete manual with very large extra schmatics.  A spare audio driver card
and extra exciter unit is included. All iron is original and has been
removed and taged for easy handling.

The transmitter is located near Tallahassee, Fl just off I-10.  The
transmitter can be moved in a standard size pickup. Help will be provided
for loading.  The transmitter can be delivered within a 200-300 mile area.

Priced at $1200.00 and I will consider a trade or partial trade.

Thanks es 73,
