I also relied immediately on receipt of the posting without any results
whatsoever and wasting time corralling resources for the pick-up. Perhaps in
the future only the actual owners of the equipment should post or contact
details should be provided, rather than attempting to be a go-between.

Thanks, Robert, VE3BE

I think he is interested in a Collins "power pebble" that is free for
the taking in Camden NJ.   (the 5 KW version was called the "power

I sent him what I could find about how to get hold of the guy who wants to
get rid of it.

This rig, if I have the right one in mind, is the last tube rig Collins made
for 1 KW AM broadcasting.  Came out around 1975.

Collins sold that part of their business to Continental who made and sold
the same design rig as the Continental 314.

It is a pulse width modulated rig.  Only tubes are pair 3-500Z in the final
and another 3-500Z for a pulse switching tube.

A couple guys have put them on 160.  Don't know about higher bands.
The B+ supply is 8 KV.  I am glad some guys can use this rig but it doesn't
interest me all that much because about all I get is high level plate
modulated class C rigs.  I understand the general theory of the class D
stuff but it's too out there for me.
Also, 8 KV is full of surprises unless you know how to deal with it.
