    Original Sunn Power Cord Needed

    Hi guy's.

    I'm looking for an original Sunn 2-prong powercord in excellent condition for a restoration project.

    Any chance anyone has one they could sell?

    Thanks!!!

    I just have to ask why you would need an original Sunn 2-prong power cord? I really don't think restoring that brand of amp that anyone is going to care really if it has an authentic power cord or not. Also, why not update the power cord and amp to have a 3-prong type installed?

    Thanks for the response.

    The amp currently has a grounded plug. This is the rare exception where a 3-prong is not necessary. The amp is for a museum collection where it needs to be all original.

    Hmmmm, Do you know what the original looks like?

    I have years worth of 2 prongs I have removed from amps. I bet some are from that era of Sunn, but not really sure which one came from which amp

    I have some new old stock two wire power cords, they are very nice cords with rubber jacket, but are not Sunn brand.

    Thanks. I have been looking for any old photos of mine with the hope of finding one with original cord but no luck. Does anyone have a close up photo of the two prong cords from 67-70?

    If you can find a picture, I have a box of power cords that I've chopped off of amps to install grounded cords. If I've got the right one, I'd be happy to send it to you.

    Do you know when and who they were made for? Might be an option but would really like to find an original. I'm surprised I can't find the one I had here from that amp. Generally that is not something I would have misplaced.

    Wish I had a close up photo of one. Still combing my old photos in case I happened to take a detailed shot of one...

    Not made for some brand of amp, I think they were Beldens, but not sure. That is not the sort of thing a technician worries about, we leave that for the amp fans.

    They would LOOK totally in place and reasonable on the amp. Would the molded plug have the exact shape of the original? Probably not.

    Images are a lot easier to find if we know the model name/number.

    Generally when I replaced a two-wire cord on an amp, I discarded it. I had no need for it, and they were usually pretty beat anyway.

    Even a shot of the receptacle on the amp would help.

    They certainly won't be sunn brand AC cords, they would have used what is commonly available at the time. So a picture will be about the only thing you have to go on.
    But put it this way, if it's this tough to figure out which is the correct type, no one will never know if you have the incorrect brand 2 prong cord on there either.

    This amp might not be original. The line cord is 10 feet long. The PT is from one of the original Sunn vendors, WTC but there is a sticker on it from 1979, about 10 years older than the amp. There is some kind of staining inside the chassis under the PT, so it might be a replacement. There is also a mod to the preamp filtering, a B+ cap has been glued down in the preamp area.

    Picture could be better, I'll post another after my camera charges up.

    If that's the one, I have the exact thing right in front of me. And, it is about 10 ft. long.

    The funny thing is, I just took it out of a Vox Essex Bass amp yesterday to install a grounded cord.

    Along the cord the following is impressed into the jacket. P. E. CO. 18/2 SJ 300V
    There is a funny little mark just after the SJ, maybe a lower case i but with no dot.

    I'm not sure you mean that as a complement?...... 4 posts to describe a simple power cord?

    Edit: n2000s, If you want it, PM me. I'll happily send it to you.

    Well, when I started reading this thread I really thought there was no way this guy was walking away from it with an original 2 prong "sunn" power cord. with combined knowledge and some junk laying around you got it. and not even just down to the look, but even down to the correct type on the cord. I believe LT too because he always seems extremely knowledgable on sunn gear. I'm pretty impressed

    Sunn amps have managed to avoid the steep appreciation of a few other brands from that era, quite luckily for prospective collectors.

    Bravo to anyone who helps vintage equipment live on, love is truly in the eyes of the beholder.

    Sunn amps were respected and substantial players back in that era.

    So with an amp as a museum piece does that mean it is never turned on and played ever again? I would assume that would be the case but not sure so that is why I ask.

    Really don't know but I'd like to think they get played occasionally. It would certainly be healthy for the amps/caps to be powered up every so often.

    And yet that's where we end up with the quandary of "safe to use..." Would your average museum worker be passionate enough to know what to do if the museum-quality amp shocks someone or a small child? Would they know enough to try to flip the plug in an effort to reduce hum? Would they know the best practices to implement if someone gets to play said museum-piece? Do they know rubber-soled shoes, dry air, no concrete, no mics, etc.?

    Are they willing to take the potential liability for electrocution?

    And this is why I personally think that even perfectly mint and completely original amps need to have 3-wore cords installed. My desire to play and to have others play these cultural icons SAFELY overrides any "collector status" they may carry. And I feel the same way about capacitors, and other routine parts.

    We add stuff to museum displays all the time - picture frames, the wires and plaster bits to the dinosaur skeletons... those are two that that come to mind easily. Nobody complains about that... if they're going to sit in a museum, even then they SHOULD be used, more than occasionally. These things are an interactive experience - they are practically meaningless if you never plug in and see what they can do. Those who have never had any interest in playing guitar don't look at these as anything particularly special, until someone plugs in, turns up, and rocks out! Then even the uninitiated and ignorant (in the truest sense of the word) will have that moment of comprehension - oh, THAT'S what that funny-looking stereo system is supposed to do!

    All of that said, I do wholeheartedly support an individual owner's right to keep his amps totally original, so long as they themselves or anyone who uses their amps are willing to accept the risks. Personally, I would try it out. I would <NOT> unleash it on the masses without conversion. My post only is speaking in terms of literal "museum pieces."
