i have one that looks like that one. But the needle indicator is misalign with the varicap. with the varicap fully closed the need should be in a 180º angle?
I just checked, with the cap fully closed, the needle should point all the way to the left, lining up with the bottommost tick mark below 160KC. With the cap fully open, it points to the opposite end of the dial.
Nice vid overall. My $.02 you didn't ask for and probably don't want... I did feel the Streetview of the old Allied building and extra details of finding an old catalog & value in current $ all seems like filler. Seeing the actual catalog entry was worthwhile and a nice addition though. Also, the transition to another video detailing the functioning of the generator was a bit jarring and could have done with better audio leveling. Might have been better to just mention the results, with maybe a couple screenshots, and include links in the details. FYI, easier to just replace the old connectors with modern BNCs and more useful in the long run. Building the specialty cables seems like more work and $, plus you're left holding onto extra cables, either getting mixed in with regular or having them stored separately, all instead of just using regular BNC. They're also a better design and easier to use than the old ones. Can always hold onto the originals to reinstall them if it turns out the original parts really matter somewhere down the line, but that's not hugely likely with most of these inexpensive old kit devices.
What kind of audio output does this thing make? Or is that just a pass through? I’m a synthesizer guy and just saw one locally for cheap, wondering if it can be abused to make some noise? Sorry for the off topic question, but thanks in advance!
If you cut off the center pin of a PL-259 flush with the phenolic insulator, it fits those connectors perfectly!
I see a future electronic engineer, here.

Add link to schematic...
What size are the connectors just got the same generator this Ray

What is the tube tester that you are using?

It's a fixed 400 Hz oscillator, and a pretty decent sine wave.
