anyone know where to download a program that will insert tubes, resesters, caps etc---?
Not sure what resesters are, but for many years I've just used Visio for most of that.
But there are simple CAD programs that might do a better job and are either free or nearly free.
tks! sorry about the spelling! was in a hurry!
I use Kicad on Linux. It's got a learning curve, but show me a CAD program that doesn't.
Once you have the schematic built, you can assign parts sizes and perform component layout and board design. It's pretty amazing.
sorry windows only ! tks!!
It is a 2-part question.
You will need a drawing program that can also handle printing, etc.
THEN you will need a library of symbols that you will be using.
This is important IF you will be drawing legacy symbols (tubes, gaseous regulators, etc.)
Bing or google EXPRESS PCB or EXPRESS SCH. Out standing programs with a direct tie to the pcb maker. When you get it done if you want pcb's you have a quote in about 10 seconds.
Try Tiny CAD, available at link below. It's free, and has tons of features.
Eagle cad has tubes in it's parts bin.
The gEDA spice suite is a little more of a pain to use, but once you've drawn up the schematic, you can then run simulations to test your design. It works better than you might think
I've been using WinDraft and WinBoard for years. All of the artwork in the old Communications Quarterly Magazine was done using my WinDraft software. At one time NTE was selling the product, but it may be discontinued now. I'd look online for a free download with a
limited "pin" count.
I use ExpressSCH and created my own vacuum tube cells. I also made some for other devices that I prefer over the ones they offer.
I also use ExpressSCH, it works good, and is free. You can create your own components, if they are not in the library.
The common technical term is “schematic capture” and as pointed out by others it can be combined with circuit PCB layout or circuit simulation.
The catch is – sometime it locks you into vendors circuit fabrication.
And as always – size does matter is some free software also! HI HI HI
You need to plan ahead what is you ultimate goal.
Another vote for express PCB, the simplest, easiest to learn, and most versatile schematic program out there, and its free. You can easily make any type symbol you want with it. This is a simple example of what it can do.
https://www.circuitlab.com/ Give "Circuit Lab" a try. All online, no download.
Tks. I have downloaded it and it works fine. I only find triode and pentode tubes in it. I think I need to do some more digging around in the program.
Nice program, but no tubes!
That is the problem that I have had with these programs -- narrow focus of component libraries.
I have used Express PC for common solid state and passive components, but for vacuum tube era work -- you really have to start building your own component library.
When you deal with "just released" ICs, you have the same problem -- but on the cutting edge.
This was really troublesome when the "new" USB bridge chips came out over past decade.
You will either end up using a few packages -- or selecting best fit and building out the library for those items missing.
Does the New ARRL Handbook still have the Vacuum Tube Pin-outs in the back ?
I know that was handy in the good old days. Could use that to build your library.
73 , Happy Easter All.
For those moving from paper to electronic,
The TDSL (Tube Data Sheet Locator) Personal Edition provides information right on your PC for a large number of vacuum tubes.
