The Classic Conion C-100F

conion c-100f


The Conion C-100F is one of the most sought after classic boomboxes. It was marketed under a few different names including the Helix HX-4365 and the Clairtone 7980 which I believe was marketed in Canada. Each version had slightly different looks but was essentially the same boombox. The Conion C-100F even had a proximity burglar alarm. It also has two shortwave channels. It's a huge boombox that uses 10 D sized batteries and epitomizes the 1980's boombox craze with it's size, flashy lights and chrome knobs.  Apparently the early models were made by Cony-Onkyo in Kobe Japan but were later produced in Korea.  This box can reach over $1000 on eBay in very good condition and even just a Cassette door alone can reach over $100.


Released: 1984

Dimensions: 75.4cm x 40.1cm x 20.4cm

Weight: 12.0kg

Output: 45W (22.5W/channel)

I've learned that apparently there was another edition of the C-100F made in 1991 as a sort of re-issue. It looks essentially the same as the original C-100F but does not have the meters in the upper left hand corner and the tape run lights that the original model had are not incorporated either.  The original C-100F had machined knobs while the re-issue had all chrome knobs.  The re-issue can get louder than the original as well. Apparently the re-issue is fairly hard to find and one recently sold for $675.00 in semi-working condition.

Update 1: A Conion C-100FF in mint condition , other than the fact that one tape deck needed new belts, sold for $1634.00. I'm not exactly sure what the difference between the C-100F and C-100FF is. Perhaps someone will chime in and let us know.

Update 2: Another Conion C-100FF sold 3-11 for $1026.00. It was in good cosmetic shape but with a broken antenna and one non-functional tape deck.

No, not right now. It’s a keeper for the time being.

I have the same one except is says Helix where the Conion emblem is. All original but has two knobs missing. I had to get the floor model in the day. I still love it and it still sounds great.

June 29th, 2010 at 6:15 pm

Hey, that’s my Conion pictured above. LOL. I owned it since new.

July 17th, 2010 at 9:23 am

I own a Conion as seen on the picture. I am soon to place it on e-bay, if any one is interested please contact me at:

August 2nd, 2010 at 5:41 pm

Really? How can you tell? It is one beautiful Conion. Very clean!

August 11th, 2010 at 6:25 pm

Hi, give us some more info on it like condition, functionality and the price you are looking for it. Perhaps someone here will make an offer.

August 11th, 2010 at 6:27 pm

Hey I just found a Conion c100f in my attic.

August 15th, 2010 at 10:50 am

It is not in mint condition but everything works well. Let me know if anyone is interested please let me know.

August 15th, 2010 at 10:53 am

I have one that needs some work in the tape section but everything else works as it should if anyone is interested in buying it.

September 27th, 2010 at 8:33 am

Does anyone know what the original price was for one of these when it came out?

I had one way back when, and I just bought one on eBay – lol!

$400.00 email me

February 23rd, 2011 at 2:34 pm

The re-issue is not louder and the sound is crappy compared to the ORIGINAL version made in Japan. The ONLY reason the price goes high on the cheaply made Korean version is because it is alot harder to find but trust me… it is made very cheap and not worth half the price.

I have a Conion C100F now. I am trying to get it repaired. Places to repair it don’t seem to exist. I found 2 shops willing to take a look. It is in good cosmetic shape, all knobs , both antennae, bottom cassette door intact. I had one of the drivers replaced 20 years ago. I plugged it up and I get NOTHING. Anyone know where to get schematics? It would be great to get the ole girl pounding again, if not then I will probably sell it for parts.

May 4th, 2011 at 7:23 pm

Update! I have just bought anotherConion c-100f for 300 dollars. The stereo and alarms work. It has all the knobs.The only things wrong is that it has no antena, the bottom tape storage drawer is gone and the bottom tape door is gone. The radio I originally owned has all of the things the second one is missing, as it is super nice cosmetically. Between the 2 I will get a working radio. Yay!!!

May 17th, 2011 at 7:54 pm

Nice going Egotrip! It’s hard to find parts for these nowadays. And, when you do find them they are expensive. Are you going to part out the one Conion once you take the parts you need?

Donald Kunkel:

I have one as listed above in very good condition and will sell to a serious buyer. Just e-mail me…Thank you.

August 6th, 2011 at 11:36 am

Thank you

im looking for a Conion C100F in good codition for sale .

November 23rd, 2011 at 7:47 pm

The C-100F was the first version and was 120 Volts AC only. The C-100FF was the second version and had switchable 120V/240V AC Selector.

April 25th, 2014 at 1:45 pm

My wife found her old C-100F in her grandmother’s garage. It’s missing the power cord, tape deck door. Both antennas are broken off and some of the knobs are bent. Does anyone know if someone out there dose quality repairs on these things?

August 28th, 2014 at 6:09 pm

It’s pretty common for the tape deck door and antennas to be broken on these units. Unfortunately that makes them fairly hard to find and expensive because they are in high demand. Still, if you check ebay regularly you might find one. You might try the Stereo2Go forum as well. Someone there might be parting one out. The parts aren’t usually cheap though. You might be able to replace the antenna and power cord with a non stock replacement. The guys at Stere2Go or Boomboxery would know. Good luck.
