That would make it considerably larger. My idea is to get a fully functional universal clock on a smallest possible PCB. It would be nice to try and make this kind of a standard unit for clock builders.

2 mounting holes would be enough for such a small board.

For the resistors: You could sell separate tube boards for different model tubes. With the 26 pin headers and anode resistors for that particular tube soldered on.
This way people can choose to wire up the tubes and solder resistors themselves or buy a tube board which is plug&play. And perhaps a track layout whhich makes it possible to break off 2 of the 6 in case you want a 4 digit clock. Kind of a mini modular system :)

By the way, how do I send a personal message on these forums???
There's some other things I'd like to ask you Michael.

I dont think selling separate boards is good idea, since there are so many different tube bases. It would be efficient.

I think I like that idea, of a tiny universal clock ... can you describe its features? You mentioned 3x2 multiplexing, could you do a direct drive? (I would guess it would be bigger and more expensive).

I like the idea of having everything on one small board! How would you attach wires to the tube sockets? i.e. just a hole in the board? Maybe some sort of speaker wire screw post?

It's all been described in the previous posts.
If you want a board with screw posts you'd better buy the pvelectronics remote tube kit . We're talking as small as possible here :)

:) building a clock from the pv electronics kit now... its so far looks very good, I now need to wire the sockets, soon will be able to turn it on and test it..

The thoughts of having a smaller board, that would fit into a smaller box, sounds like a good idea. Might make more options for a clock case possible.

The thoughts of a temp display sounds really good:)
