[Amps] HA1YA amplifier modules

[Sandy Ganz]

Does anyone have any experiance with the HA1YA amplifier modules? I am
looking at building a VHF amp and like that I can get the VHF module
complete which is the hard part for me to make. I'm looking at the 750w
units with either a pair of GI-7's or one with a single GU-74. I'm
favoring the single GU-74 tetrode tube vs the triode pair.
Advantages/Disadvanges to
either? Any other links to kit's or semi assembeled RF sections?

New to the list as well.

Thanks

Sandy
