Default Pcb software for tube designs

Can anyone tell me which software package for pcb design has tube base outlines in its parts library. I have not found one yet. I had to make up the outline but am not happy with it.

Thanks .

Hi !

I'm also interested for library for P-CAD or any other PCB software with tube support.

Thanks,
Leon

Why bother. Unless you plan on doing a production run or building some complicated ARC type behemoth, there isn't a need. Point to point it. The parts are few in number and usually larger. It'll sound better anyway.

Cheers

I use CadSoft Eagle (http://www.cadsoft.de).

There is a seperate package/library you can download (tubes.zip)
that has quite a large list tubes (mainly Novel and Octal types).
I also find it very simple to use.

Regards,
Tim

I have modified the library a little to make the pads and holes
a little bit bigger for Novel tubes.
Works a bit better with my current supply for Ceramic PCB mount
based (from TheTubeStore).

Regards,
Tim

All,
i have such on my back burner but it is not yet ready. It is an AutoCAD plug-in, written in LISP and also supports p2p-wiring as the logic behind is not coupled to the graphics as is with usual ECADs. PCB components, p2p components, schematic symbols are completely equivalent and contain the same data. To enable bidirectional annotation. But one warning: fancy rubber bands and density histograms and autorouters will not be part of the show. It is not your task to check connection state but it is your task to draw routes on the PCB and wires and lines in schematics yourself. OTOH, if oyu know what you are doing, you can use teardrops and other fancy PCB stunts like provided only by $$$$ ECADS like PADDS.

It is part of my AutoCAD utilities which will be downloadable from my website soon.

Watch out for my announcement that NetCAD is ready if this part of the routines are the only part of interest to you.

Libraries: can be created from AutoCAD drawings; i will provide example drawings.
Consider this is real CAD and you can draw everything like you want it, not as withing the limited limits of ECAD.
The routines also contain a powerful automatic symbol/component creator and update routines for existing library drawings.
If i find there is sufficient interest, i will increase my priorities on that project; currently priorities are low.

Below i have a schematic drawn with it.It is an obsolete version of my phono preamp

Iīm using Protel 99SE for simulation and PCB. At the moment I only have a problem with the tube library, īcause 6DJ8 and 12AT7 didnīt appear, but Itīs no problem If you only need the PCB facility.

Marcelo

Ivex software has schematic layout and PCB design, and decent tube libraries for each. They've also got some Spice libraries for simulating tube circuits.

Default Most of the PCB programs have edit

Ultiboard has a component shape editor. It allows one to draw lines, arcs, pads etc. I've used this with some of the National Semi chips like the LMD18201 H-Bridge Controller and the LM3875 single chip amp as the pins are on 67 mil centers.

Ultiboard isn't the easiest program to use, but if you are going to do anything with more than a few components you really should have a program which allows you to create and route nets.
