Swan 350/117C power cord connector

(1/2) > >>

David P Smith:
I have a Swan 350 with 117C power supply that appears complete except for the power cord.

Is there an online source for the power connector and/or wiring diagram to use this power supply on standard 120VAC/60Hz?

The radio looks to be intact and I have been cleaning it up--would like to see if it is still working.

Thanks,

 W6DPS-

It sounds like you really have an excellent find for yourself. I collect and repair antique radios including classic Amateur Radio equipment like you have. Before you do anything else, I would carefully visually inspect the inside top chassis and bottom chassis of the transceiver and power supply. This is routine to detect components that have discolored from overheating, faulty solder connections, wiring issues, etc. Then I would find someone who has a tube tester and test all the tubes one at a time. If you do not know of any local Radio Amateurs who have a tube tester, try a local antique radio club. Once you have done this check the receiver by turning it on but with the AF gain all the way down. If there is only a slight amount of AC hum this is acceptable. Anything much louder you will have to replace the power supply filter capacitors. Does the power supply AC cord and interconnect cord physically appear in good condition? This will get you started. When you have done all this report back on this topic on what you have found. I am happy to assist you. I hope this will help down the correct path!

Bob Scupp:
My apologies! You did say you did not have an AC cord.
You can find an instruction manual for the Swan 350 on BAMA's website:

I have found a manual, checked the tubes, cleaned the cobwebs out fo the chassis, etc.

I still haven't found a connector to feed power into the 117C.

I also discovered the radio has a mod to allow selectable sidebands.

Dave-

Thank you very much for the update on your Swan 350 w/power supply. Ok on the mod. That is really interesting! That power cord may be a problem finding one. I do not know if it is generic but you could try an electronic surplus store if one is available. Are there any Amateur Radio outlets (stores) where you are? Another idea is to post your need for the AC cord on Amateur Radio Swap and Sell websites in your area. Or list it on the air if you have any local Swapnets? Check with local clubs or research Swan users groups on the Internet. If you need any more assistance please send me more e-mail or post it here.
