    I think you could find the socket from Antique Radio Supply
    The Swan 500 manual will provide a basic guide on how the accessory socket is hooked up inside of the radio. You will have to do some working between the two schematics to get it wired right.

    I did end up giving the presentation and it went well.

    For casual operating, I prefer my hollow state rigs over my more modern solid state stuff. While the no tune aspect of my IC-765, and IC-740 really come in handy for the S&P/frequency and band hopping style of operating I do (due to running 5 watts [QRP], or 100 watts of power) during contests, since I don't have spend time re-peaking the finals and/or the driver/preselector after major frequency changes (that gets to be a drag after a while), I prefer the audio of my tube rigs. And yes, my tube radios are sooooo quiet compared to even my relatively modern IC-765, which make listening quite bit less fatiguing on my ears. For the TDN, I plan on using my Yaesu FTdx-401 (ya gotta love that it has 20 tubes!). It's good for about 250-300 watts (PEP). I'd use my Swan 700CX (which'll do about 400 watts PEP), but I haven't gotten around to neutralizing the finals on that radio yet. :eek:

    Trivia of the day:

    The 8 pin is called "octal"

    The 11 pin is called "magnal"

    Never saw a name for the 9 pin.


    One work-around, if you don't mind modding the rig, is to replace the 9 pin connectors with the much more common 11 pin.

    9 = nonuple

    Only marginally on-topic....

    The day I finally found a Gonset G-76 at a hamfest, I looked at the power connector, made some simple notes, and went looking for one. Lo and behold somebody had one and gave it to me for free!

    That happens more often that we give credit for.
    Well this is more on topic than the silliness about naming connectors for the number of pins on them.
    No self respecting Geek would do that.
