Hello from a longtime lurker….
 
The point first…I need 2 clear 568(0) tubes :-(
 
The back story….Ages ago in the 70s when I was in my teens I built a very
dangerous small 4 tube nixie clock.. using modified guts from an old
pinball machine and an electric clock motor from an old range. As the
second hand on the clock made an electrical contact on a set of points from
a distributor… The modified pinball score counters would make contact and
change the numbers on the Boroughs tubes… I can still remember the smell
of the ozium and the sound of the zorching ..Sort of think of bumper cars
:-) and the spark and smell!
Time moves forward and I found a guy named Jeff Thomas and bought one of
his very early NIxie sat clocks….Think of opening the box and getting a
major prize… Just like the leg lamp in Christmas story!
I love the clock! It stopped working… I find a guy That is really really
helpful and incredibly knowledgeable and nice! Michael at bad nixie Got it
up and running again beautifully with a new gps puck…with a motion detector
…new firmware and made all necessary component mods ! He does amazing work.
I can’t recommend him enough!
The clock sat on the window sill since I got it about a decade ago… while
the clock was out for repair… The cat who came to my home after the clock
about 6 years ago…Decides that it’s now OK to jump up on the vacant
windowsill. Clock comes back… Clock is working for about three months…
Owner comes home last Thursday night and notices clock on floor!
One tube completely smashed and the other tube is missing a tiny point at
the top… Just enough to have let all the gas out. Fortunately the other
four are in good working condition.
 
I need two good functioning clear tubes.. if anyone here has a pair I am
very willing to talk and spend within the “new normal”… Or if anybody has
advice on where to get them I would be very appreciative for your
recommendations. I love this clock I really would like to get it going
again… Soon!
 
I already have a new spot for it in a sealed glass bookcase!!!
 
admittedly I’m a little conflicted because I love the clock… And love the
cat… And currently in that order :-)
 
Any and all help is greatly appreciated!

Nice find Martin! I have a collection of Eldorado counters... they're
really nice. What's the one on the right with seemingly no markings? I'm
curious what that thing is?

The one to the right has a decimal point, which would suggest voltage. But
it has a lot of precision for something that old.
Maybe it's a digital readout for something like a machine tool or a
microscope positioning system ? The 'space-age' format might be appropriate
for a something like an electron microscope.

I think I've seen that display on a CMM. But the front panel had markings
IIRC.
 
Terry S <tschw...@gmail.com>: Jun 21 07:13PM -0700

I should say a similar display. It had multiple nixie readouts.

I think it may be similar to my X Y display for milling or lathe back in
the day. I have a large nixie display that shows X and Y. The vertical on
the back maybe gives it away idk?
 
I'll eventually put up video of mine. I have so much stuff it's out of
control. I always think wow that's really cool then move onto something
else. Now my house is full of test gear. It's all got a story though so I
hope to one day tell it in more detail. Vintage display technology nut,
voltnut, and timenut is basically me outside of work.

The Beehive one looks pretty rare to me. If it's from the 1930's that's a
keeper. I've seen the other one before... not sure what the use was but
they're more common.

Yep, UK, I got the bulbs from a salty old sailor ( actually a photographer :) ) in a London boatyard when I fixed his RAID disk array for him! He got them in a jumble sale years ago. Funny where these things turn up...

As some of you know, I am fond of vintage coin slot amusement machines.
If they contain nixie tubes, then what's not to like even more?
 
The Golden Mint slot machine was made by Sturgeon Electronic
Manufacturing Co. Ltd. of Bognor-Regis, Sussex, England in the 1960s.
There were 240 pennies in a pound, so this was not gambling for high stakes.

I hope you've been able to visit Tim Hunkin's creations. He provides some
clips of them on his youtube videos (secret life of components). No idea
when I'll ever be in the UK again, but I'll be sure to visit Novelty
Automation.

I don't have a date for this rare English coin-operated machine, nor
even a manufacturer. Nor do I have a picture of it lit up. You set a
number - today's stock price, or whatever - on the nixies using five key
switches on the front panel. The payoff depends on how many of the five
numbers you match. The reels are motor driven steppers. The five 'match'
nixies in the round windows are 3 inches in diameter, very desirable. I
wish I had more information.

It's unusual (for me, at least) to see them in an application that isn't
electronics or laboratory. Even in pinballs I've never seen them - they
went from stepper reels to panaplex panels and then to dot-matrix.

Hello.
Last weekend it was [electronics] flea market time! It was very nice to
attend this kind of event after 9 months, while it was sad to see on the
tables "new" stuff that belonged to who has passed away.
 
Besides the whole display board from an expensive Rohde&Schwarz EK47
receiver with sockets, 74141 and 6x ZM1182 Nixies, I scored a NIB Philips
CRT: *DP7-32-01*. While the cardboard box has been opened, the tube is
still sealed in the plastic bag and part of the marking has stuck to it.
 
While I know the DG7-32 part, I cannot find online a datasheet for DP7-32
CRT. Comparing other Philips datasheets (
https://frank.pocnet.net/sheetsD1.html) the *DP* marking should refer to
dual-color/persistence tube: blue with short, greenish-yellow with long
persistence.
 
Am I correct to assume that D*G*7-32 and D*P*7-32 should have the same
electrical characteristics?
 
A clock with this kind of tube does require a custom firmware with proper
effects.

Hi Paolo,
 

 
Indeed the tubes are electrically identical.
 
The second letter in the type number denotes the phosphor color and properties.
 
The tube has a symmetrical deflection. Important for a clock J
 

 
Here a copy of my Philips Pocket Book for Ham’s with the explanation of the Pro Electron Code (European equivalent of Jedec) and the data of your tube.
 

 
Have fun,
 
eric

Isn't that the one used in the Marantz 10B (and presumably the Marantz
10)? You can probably infer a useful set of operating conditions from the
service manual.

Whittaker Bros., from Shaw in Lancashire, England, produced a variety of
simple coin-operated machines with interchangeable perspex screens.
 
Two nixie tubes were placed in the eyes of various characters. Your job
is to put a coin in and use a button to stop the display on winning
numbers, to gain a payout.
 
I have details of machines various called "Beat the Blinkers", "Beat the
Bandit" and "Beat the Clown".
 
The machines featured a standard GPO (the UK Post Office) Strowger
uniselector, a bell-type system to step the selector and the two nixie
tubes.
