However they will be fairly affordable: in any case well under $10 each to people here.

Hi Ian,
I would also be interested in these. Please let me know if you still have tubes to sell.

Currently I only have some nice little Minitrons , but they're not really a good choice for clock building.

Torsten

Yes, I received the first batch, I will be selling some very shortly when I have tested them.

I might be interested in some too. I have a couple of DA2900. I can't decide whether I should try and get 4 similar tubes, 6 completely different tubes or just wait for more DA2900 to turn up (which seems unlikely!). Either way, hardware to run them would be interesting. Especially if it is wemos based - then I could shove my own software onto it.

Hi,
it's a bit off topic - I just ordered PCBs to build a test adapter with contact probes from Feinmetall for PCBs using NOVAL sockets. It will make testing of my clock PCBs much easier. Most likely I will have some PCBs left if anyone is interested. The biggest problem is to get the contact probes and holders in small quantities...

Regards,
Torsten

Hi Ian,
any news yet? BTW, could you please give me the exact dimensions of the DA-2000? I was planning to build a clock around by existing cases and a design similar to the existing one, but according to the Radiomuseum the tubes are bigger than the DT1704 (20mm ./. 18mm). But it looks as if the diameter at the base (socket) is a bit smaller.

Another point is to find a small lamp for the colon separator. The main problem could be to find a lamp with a similar lifetime than the Numitrons (~50000h).

With best regards,
Torsten
