At first I thought just the tubes for this must have cost several thousand dollars, but it turns out you can buy these 6N3Ps for as little as 50 cents a pop (allegedly Soviet NOS), which probably makes these the lowest-cost vacuum tubes around, by far!

I bet there are more that aren't visible, so it should cost a few hundred dollars. Still, it's a huge steal compared to what a comparable tube computer would have cost back in the 60s.
