    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.

    It's easy.

    But there are simple CAD programs that might do a better job and are either free or nearly free.

    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.

    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.

    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.
