I received the auction today. Good and Bad news. Bad news is that 1 of the 11 tubes is bad. Cracked at the base, but difficult to see. I proposed a refund of 1/12th of the payment.12th being the socket and known bad tube instead of requesting 1/11th. So, 10 more tubes for

If you already have any nixie clock then I would pinch the 170V from there. Make sure you run the anode via a suitable series resistor. Use the specifications for the device to calculate the appropriate value R = (supply volts-maintaining volts)/Cathode Current so a tube with maintaining volts

Cheap HV power supply method : I built my own HV power supply for testing nixies.  Look around at second hand or thrift type stores for a single use camera with flash and manual film advance with a single or two AA batteries    Ones with a neon ready light are best  These have a 330 volt DC

John, Marcin used to sell (many years ago) a simple tester with flying leads that you could just attach to each cathode (and one for the anode) and it would automagically cycle around the digits or you could manually advance. All you really need is a 170V DC supply, suitable resistor (8K2 or

Ahh, this is for testing them as they arrive, then shelving them for future projects. I saw Marcin Saj has a few testers, but they seem more for socket-pin tubes. The knobs also don't have settings I can set it to for different tubes, or a display for the current voltage or current. -- You

My Nixie watches use B5870 tubes with flexible wire leads. I use tweezers to form them to the arrangement of the socket and plug them in. I recommend that you solder socket pins into one digit of your clock, and plug each tube into that socket before soldering it in. Better yet, build the clock

I like to use "clamp type test probes" for that purpose, they work quite well and are easier to deal with than alligator connectors. Jens On 2020-01-30 11:23 a.m., John Snow wrote: I have some not-NOS nixies arriving, and they have flying leads instead of pins - what's the best way to test

I have some not-NOS nixies arriving, and they have flying leads instead of pins - what's the best way to test them prior to soldering them into place? I've heard of using a plasma ball to ionise the gas to see if it's still sealed, but is there a gadget I can buy that clips onto the leads? I'd
