Z504S dekatron replacement

[Oleg B]

Hi, I’ve been designing and building Nixie’s clocks since 1970. The first one has been launched in 1973 and is still up and running. One of my recent clocks is combination of Nixies (ZM 1040) and dekatrons (Z504S) driven by PICAXE chips with brightness control, alarms, chimes and WWVB synchronization. After 4 years of operation one of the dekatrons start loosing the brightness. I cannot find replacement on eBay and wondering if someone from this group has one Z504S (or ZM1070 or CV8292) for sale.

Any help/ advice would be highly appreciated.

Kind Regards,

OlegB
