Hi lcc,
there are tubes meant for use in sockets which have quite thick and short pins and such that are meant for soldering with quite thin wires.

I would urgently recommend never to try to solder a tube meant for use in sockets! Through the thick and short pin you will transfer too much heat to the vacuum sealing of the pin. You will most likely damage the vacuum sealing of the pin which doesn't need to have an immediate effect.

Regards,
Torsten

Good point Torsten. I had not thought of that. I guess we will see how my soldered tubes hold up over time. So far so good.

Look into it later when the dust is clearing off the crater.

this is going to be a tricky one haven't soldered yet have three other numitron clocks that have sockets for the tubes and i am very reluctant to solder them in on this kit could get sockets and wire them up to the board

Hi,
I know there are special low temperature solders, like this older solder wire on eBay or this lead free solder paste from Almit.

But I don't know how suitable they are for such a job.

Regards,
Torsten

HI
when i get round to soldering them my plan is to have the pins flush with the bottom of the PCB and i have a pair of tweezers that will clamp on to the pin right where it meet the glass so hopefully will act as a heat sink
