 So I decided to do a real test:
 Two ARC-5 receivers, side-by-side on the same antenna,
 receiving the same WWV 5 MC signal
 the first with a completely "stock" audio output
 and the second with one of the more common
 "CQ-VooDoo" extra-tube hacks.
 (note: both files are 0.5 megs)

 The first clip is the "stock" receiver, outputting its
 clear, crisp and ample audio:

 The second is from the ARC-5 receiver
 that has had the "CQ-VooDoo" audio hack done.
 If you listen closely, the distortion and
 chaotic noises on the WWV signal created
 by this "VooDoo" hack are obvious:

 You can't beat a scientific experiment for proving a point!
