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.

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.
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...

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.

Thanks 'Nigel', your input much appreciated, was trying 'The Easy Option' ..... As on does .... smile, smile, smile....

My CAD package has a "circular" package option which does valves pretty quickly from a few parameters.
I do a 10 pin package in a circle then remove pin 10 to get a 9 pin B9A outline.
Hi there to ALL.... ALL SORTED !!!!! I found a link here ... Adding custom components to ExpressSch - Hoffman Ampifiers Guitar Tube amp forum .... Many thanks to " EL84 " for their infomation. I hope that this info. will be of help to others. I did have trouble installing into the 'Custom Symbols', but thanks to my son, that is in the computer industry, he was able to install the new symbols in the standard 'Library Components' and I have 'saved' the ones that I would use most into 'Favorite'....
Thanks for ALL your input and hope that I have returned the favour and input some info. that others could use too !!!
Best wishes from New Zealand....

It's not CAD but I have used it to do design work for use on a cnc router. The package is called iDraw. Its a bit like a Corel draw clone, I'm very pleased with the software anyhow.
If you like working in DOS, I have the libraries for some single and multiple tubes for the old DOS OrCAD SDTIII (like double triodes, ECL82/84/85), etc...and can share it with you.
Hi NZ...I am having trouble installing the custom symbals....I have extracted them into the expressPCB folder but they do not show in the list. What did your son do????
Help will be much appreciated
If you are familiar with AutoCAD (or would like to be) but don't want to pay the price, try DraftSight. It's free, is modeled after AutoCAD (so looks and works the same), uses the same DWG file type (so files are interchangeable between the two apps) and is available for both Mac and PC. Yes, you'll have to create your own graphic library, but once done once, done forever. It's also, probably needless to say, perfect for drawing up chassis layouts.
