I have gotten back into SWL'ing lately ... (ain't like it used to be
either!)

Got a couple of old Hallicrafter receiver rigs and replaced the front end
tubes with some GaAs semi circuits, done on a pcb board and serves as a
direct replacement for the tubes--except for the need of filament current,
they are "work-a-likes" ... gawd, bet those old boys wish they would've
have had those when they engineered the rigs ... I just love the look of
these old "solid" rigs! (solid as in "weighs a ton!)

I am interested in anyone else who has "tweaked" old rigs with various
"kludges" and gotten good results? Comments? Advise? Construction?
Results? Ideas? Unique construction? Anything? ...

Now, this post might NOT be "right on topic" for antennas, but darn close,
we DO have to consider what our antennas feed, right?

Warm regards,
JS

Hi John,
You might want to post in the boatanchors group or the shortwave group
also.
I well recall collecting "tubistors" at Dayton some years back for a friend
who wanted them for his S line. They were plug in replacements for the
tubes.
