So. I bought this cheap tube tester test the tubes on my 38-116, this is just a cheap one to test for continuity but could it be used to test for more?

It is a a model FT435. I just plugged them into the octal port and then turned on the power to see if the lights lit up... does anyone know what the other red and black wires are for? Are they hot, how would you use them, I just left them alone.

So most of them seemed to light up fine, but as you can see a couple of them just barely lit up the lighthttps://www.flickr.com/photos/58236519@N00/16482485859/in/photostream/
and it seemed to flicker a bit, two tubes did this. But most of the tubes looked very bright when plugged in like thishttps://www.flickr.com/photos/58236519@N00/16642701416/in/photostream/

There was one tube that felt like the tube part was kind of separated from the black base and it kind of wiggled and spun around and you could here like wires moving sound so I figured it would be shot but when I plugged it in the indicator light shinned brightly.... But I really don't think I should put it back in, it feels like it was going to fall apart anytime.

I know each tube is different and probably has different outputs but for the two tubes that barely lit up, is it safe to assume that they need replaced or is this common. All of the others varied in indicator light intensity a little bit but they were all pretty bright. So any thoughts on should any of these be replaced.

Also one of them seemed like the plug on the chassis was a bit wiggly.
