I have several 1kW television transmitter modules that will work fine on
6 meters.

A full write up and pictures are available here.

These are the "low-split" modules that do not require any further
modification.

With some work, these amplifiers will produce well over 1kW on 2 meters.

RF input and DC input connectors are included but other parts are needed
to get operational. DC power supply 50V @ 50A, RF coaxial relays,
cooling fans, etc. Some assembly required.

Price as per the web page above, $370 plus packing and shipping from
Nova Scotia, Canada. Total cost approx $455 - $470. Proceeds of the
sale go towards my ham club.
