The OG-7 is identical to the OG-4, but with an argon fill gas. The OG-7 also has identical pinouts and internal construction as the OG-4, but its counting speed is rated at a brisk 50 kHz.

Soviet OG-7 50kHz counter. The OG-4 and OG-7 are arguably the best choice tube for a novelty project. They are easier to drive than the single-pulse OG-3, and can be readily bought from sources like eBay in fairly large quantities.

OG-7
