Numeric Companion Tube for Z567M

[Mac Doktor]

I have a Z567M symbol tube (+, −, ~) that came with my Useless Nixie Device. What is the numeric tube that it was used with? I'd like to have one to display alongside it. Note that it has the red coating.

Thanks.

Thank you. Bonus question: what's a reasonable price range? It needs to at least look new.

[Nicholas Stock]

New ones appear to be anywhere from $55 to $65 a pop at the moment (or thereabouts)....used ones aren't going for much less. The Z5660M is the clear version.

New for a little more.

Best overall tube value in the market today, based on size, digit shape and quality.

Best tube overall, period. At least for me. Good size, digit surface to total surface ratio, nice tube proportions (Z568M are too bulky in my opinion), curved 6 an 9, thin anode mesh. They also seem to be long life, I have a clock running 24/7 for six years with no sign of wear - and those tubes were previously used for many years in Meratronik equipment. Don't be afraid of buying used Z566M if all the digits work properly at the time of purchase and the red coating isn't damaged.

Excellent. My thanks to everyone for the quick replies.
