Please Help! is working on an updated Manuela design and this new clock will allow the user to select from a variety of top-view tubes.  Jürgen has been working hard on the design and he has a question for the community.  One of the options is a set of six SIEMENS red coated nixie tubes.  Alternatively, Jürgen can coat much cheaper IN-12 tubes and achieve a similar look.  Which option do you prefer:

Option 1: Siemens. And tell me when it's ready to ship. That enclosure looks great!

Siemens - although will most likely remove the red tint....

I vote for the real thing, The Siemens Tubes. I would ask though how he plans to coat the IN-12's? I have done this with a glass paint and although it looks great, it is not a very durable finish.

Enclosures are arrived...

Hi @ all,

the enclosures are arrived today so I'm ready now for delivery... :D
And the new frosted (not white) front cover looks awesome :roll:

As I've told Brian, the first ordered clock "kits" with AEG / TELEFUNKEN or SIEMENS tubes you get ready assembled and tested for free (this means a complete clock ready to go).

Quoting Michael Barile:
I would ask though how he plans to coat the IN-12's?

It's very easy: First clean all tubes with dipping into spiritus. This specially removes the "OTK" stamp.
Than fill your dipping laquer into a glass jar and dip every dried tube fully into the lacquer. Now keep them drying for around 30 mins.
As you have now also lacquered the socket - this gives a good isolation - now only the sockets needs a bath in brush cleaner to remove the lacquer from the socket pins.
The coating is absolutely durable...
but this is a big efford and only practical when lacquering a bigger batch of tubes - not only 6 pcs...
