Here are seven tube based decimal counting units, Beckman 775 and 775A's. These predate the Nixie counting modules and. Would make a wonderful digital clock, all tube based. One module is missing a tube and another tube looks to have lost it's vacuum. But otherwise they are in good condition for their age.
Tubes are 5963's or 12AV7's. See my other auctions for more vintage electronics.
