CAD for Tube circuits

[NZkeith]

Greetings Folks.... Firstly ...." diyAudio ", what a great forum and always somebody out there willing to share and help
My questiion:- I am still very much ' A Tube Virgin ', although being over 60 already. I have a few circuits that work really well and would like to 'draught' them in a CAD program. I have found quite a few FREEWARE packages, BUT very few with the basic tube amplifier components, diodes, triodes, pentodes, resistors and different caps etc., ALL in one place. I have tried 'TinyCAD', but struggle to find an EASY WAY to create say a 'diode' within the package, as there are only 3 valves 'supplied'.
As this is only a hobby, one does not want to go out and spend $100's on something that you might use only a few times.
I would really appreciate ANY input and help......
Very best wishes and thanks in anticipation.....

There are packages for ExpressSCH/ExpressPCB with tubes. And it's free!

If you have Visio, there's tubes in the library as well.

SY I just tried a new download from ExpressPCB and still don't have tubes! Is this someplace else or did you roll your own custom symbols?

No, I got the tube package off another site (years ago, can't remember which, but Google is your friend). I think there's a Yahoo group for ExpressPCB where there are also libraries.

That makes sense. I just drew my own. I also had to redraw some of the transistors because on some pin 1 is the collector and on others it is not!

Hello there Simon, thanks for your input.... YES... You are correct.... ExpressPCB does not seem to have ANY tubes, yet it does look like a great package. Just wondering if anyone has or knows of any 'tube/valve' add-ons for ExPCB ????

Thanks again.... looks like quite a good thread has been started, could well be a common problem....

Cheers, be assured, all inputs well appreciated...

Hi there too ALL.... I have just done a bit of a GOOGLE search and THERE ARE some add-ons for ExpressPCB..... Actually found a link to a thread in diyAudio !!!!!!! There does not appear to be any tube/valves, but the various sockets and MANY components are there. Kindly posted by member " Ivey " of diyAudio....

Thanks for that...

Most CAD packages allow designing of your own components.
This is often better than relying on someone elses attempt.
You can make pads the size you want.
