Questar Power Cord
Posted 16 February 2014 - 03:05 AM
Does anyone know if there is an after market cord that will work. I need the un-polarized cord, which I don't believe is available from Questar and longer.
Thanks for any suggestions.

Questar will service any scope they ever made. They will likely have a new power cord for your Duplex. Questar works best when you give them a phone call and ask for Jim Reichert. You can also have yourself listed as the new owner of the Duplex. Questar keeps a record of all their scopes.
Now even without a proper cord, the Q is still a very enjoyable scope, so make sure you get out under the stars and have some fun with it.

Thanks much for responding to my post and for the contact name at Questar. I believe the person I bought the scope from is going to contact Questar on my behalf.
The Questar website indicates that the old style, non-polarized power cord is no longer available and the new polarized cord requires a change-out of the receptacle in the base of the Q. I was hoping to simplify the process by finding an old style power cord through some other source. Probably a long shot to find a similar cord.
Thanks again. Clear skies to you and warm regards,

Did you miss my post ? The non-polarized ones are called "Cheaters" and are available on Ebay. See the link I provided. The cord in the listing is the same one that came with my 1961 Questar and is non polarized. You just need to replace the 110 volt plug end and that will cost about $2.

So sorry, I did miss your post. Thanks much, I'll check it out.
Take care, Tim

Hi Tim. Are you sure you need an "UNPOLARIZED" cord ?
Here is a photo showing the base and the cord of our 1971 Questar. The two pins in the base are a different size, and so are the plug prongs; that says "polarized" to me.

You are correct, the base in the picture is polarized. This is interesting because the Questar I bought is a 1978, but has the base plug with the prongs the same size, which would mean it is unpolarized.
I had better look again to make sure. Thanks for the great picture.

I just looked again and both prongs are the same size. Curious that the earlier version is polarized, I would think it should be the other way around.
Wonder if anyone knows when Questar made the switch.
Thanks again, Tim

" NOTE: The electrical plug is polarized and goes in only one way. If your cord becomes loose you can repair it by squeezing plug with pliers to close holes. "
I removed the base cover on our Q for a look, and both wires going into the motor housing are the same color, black.
Unless you have an electrical tester, you might want to give Questar a call at 1 (215) 862-5277

I'll post the results once I've finished the install.
Thanks and best wishes, Tim

You can rely on Questar for your scope needs.

What I have found out is that there are tow options. You can get old power cords on eBay that will work with Questars that have the un-polarized plug. They are $12 and you will have to cut off one end and install a common lamp cord plug. Total cost about $15.
The other option is get a replacement cord setup from Questar for about $16 plus shipping. This includes a polarized cord and a replacement plug assembly that needs to be installed in the base of the Q in place of the non-polarized plug assembly. Based on the picture that was shown in this forum thread, it should be very simple to replace the plug in the base of the Q.
The second option is probably the best from a safety point of view, but either approach will work.
Thanks again to all who answered my initial question, clear skies!
