A digital desk clock with 4 old Nixie tubes, type ZM1000, used. Red PCB version.
Electrically this is a fully operational clock as sold in my shop www.etsy.com/shop/betatronics . IT HAS TWO (purely cosmetic) FLAWS; there are some fine scratches on the top aluminium plate (really fine scratches, see 3rd photo), and it is fitted with used ZM1000 tubes. Apart from that, you will receive the same quality clock with printed instruction manual. The price is accordingly reduced.
This Nixie tube clock is fitted with rare western made ZM1000 type Nixie tubes seated on their (even rarer) original sockets. The listed clocks are the last ones available. The 4 ZM1000 type Nixie tubes are all the same quality brand (Valvo, RTC, Philips) with equal internal construction. (Independent of the brand, the tubes I have were all made at the Philips Heerlen factory, Netherlands.)
Two custom-cut silver anodized aluminum plates protect the user from touching the bare, still visible board. This gives the clock an industrial and 'geeky' look. The clock is hand-soldered, hand-assembled, and tested. It will keep track of time even with no power connected thanks to the large internal supercapacitor. It comes with a printed user manual and one-year limited warranty. You will need to provide your own 9VDC 500mA wall-plug power adapter with a standard 5.5mm/2.1mm circular connector.
