[Hallicrafters] Vacuum tubes discovered at NAB

[Ed]

I would like to share this with all of you, my friend just returned from NAB this morning and this is a line from his email:
I attended a session Saturday at NAB - about VACUUM TUBES. They billed it as the first session at NAB about tubes in 30 years. It concentrated on the sound from tube-type audio gear (is it better or just different??). Thought about you.
