Everybody knows that one inch of bad wire...
Sorry, I couldn't resist it.
Follow Ups:
Oh but it's true, it's true. This is why, for the test to be valid, you have to use the same wire as the wire leading to and from the fuse holder. :-)
I am so grateful that I received a good electronic education early in life so I wouldn't fall into the many traps of this nutty hobby.

"Still Working the Problem"
I do understand, Tre'. As an example, when I started fooling around with upgrading old tube equipment back in the early 1990s, a friend suggested I take a basic electricity course, which I did.
I was a Stereophile reader at the time, and when the instructor described electrons moving through copper wire, I clearly remember thinking to myself, "Then how can wire affect 'sound'?". Yet I had taken part in a blind (but not double-blind) impromptu interconnect listening test, where differences were heard by those of us sitting in front of the speakers.
My point is, if a basic electricity class caused doubts, then I can only imagine what having an engineering degree might do to my thinking. Voodoo and magic come to mind. I recently found a post by Twystd (link below), where he was comparing unbypassed cathode resistors, metal film to carbon film. His EE friend was there, heard the difference, and, "He immediately got angry and accused me of trickery, then stormed out."
So, like Lew, I'm somewhere in the middle. I have my doubts, but try and keep an open mind. Call it a Missourian "show me" approach, even though I've never been to Missouri.
But there is a problem right out of the gate. Do you know what unbypassed cathode resistors do to the performance of a tube?I'm not saying that resistors all sound the same, they don't. But the overall sound of a circuit using an unbypassed cathode resistor will be greatly compromised to start with so you might just end up just comparing crap to more crap.
I don't find much value in that.

"But the overall sound of a circuit using an unbypassed cathode resistor will be greatly compromised to start with so you might just end up just comparing crap to more crap."
After a quick look at the schematics, I don't believe any of my equipment uses cathode bypass caps!
At the risk of getting a legitimate STFU from the original poster, I'll post any further questions I have over on DIY Tubes.
Thanks Tre'!
