[Boatanchors] VHF linear amp?

[Ron VE8RT]

Hi Bill,

   before I ask how much are you looking to get, I'll ask what the
shipping weight would be :-)

   At the moment I don't have a 100W on 6M, only 10W from an IC 703 or
a FT 726R.  I do want more power, obviously, on 6M it would make
putting a yagi up worthwhile.

I have plenty of FM broadcast pulls, sockets, chimneys, etc.  I used to replace the driver tubes, annually, even if they were still providing full drive to the PA.  You could always hombrew an amp.
