Very cool.

Awesome piece of gear! These demonstrations are a fantastic resource for those interested in these great vintage equipment! Maybe you still can find those glass tube oscillators on ebay or vintage components' surplus shops. Their prices will vary all over the place (as will their descriptions!) so patience and perseverance will be required but I expect they'd pop up somewhere within 2-4 years' time. I don't know what kind of demand there is for them from ham operators that use vintage gear or from vintage RF equipment restorers but it seems this is a low frequency device so I'd imagine there shouldn't be any really.

Hi Tom...I have one of these units, and it's missing the crystals as well. I'm really interested in how you put those solid state oscillators in. I'd like to be able to bring mine to life. Please let me know if you'd be willing to show us that!

I got the bare 8 pin octal tube base with the pins and just soldered in the 100 Khz crystals, pins 3 & 7. All parts found at my local surplus, I'm sure you could find the parts on ebay. I think I could have bought the oem style but they were a hundred bucks or so, instead of like 10 bucks. oem tube BG9D-S

I want to buy this machine, is that possible?

Beautiful, I have a HP 334a distortion analyzer. I absolutely love looking at old HP circuit layout
