I have recently bought a non working Sansui CP-7 component system. It's the digital tuner version. How rare are these? I've never seen one before. It powers up but no sound the digital display is unreadable. The cassette seems to be stuck in play mode as the heads are raised and won't go down. Its in great physical condition and needs a clean. Is this worth spending some money on? I paid a ridiculous £3 for it. Any ideas? Thanks.

Shortly before 10:00PM Eastern Time (ET) tonight, I posted a message on YouTube commenting on a video clip (under four minutes in length) that I'd watched a while earlier today. Sansui boomboxes aren't a cheap lot; I found three on eBay minutes ago with the search term "Sansui CP-7." (Two aren’t CP-7s, though.) They each cost hundreds of dollars before an extra financial lift is needed for the cost to ship that bulk to you.

But I seem to remember reading or hearing somewhere that Sansui sound systems were of above-average quality -- perhaps even top-class machines -- "back in the day." (Though the "average" person on the street might not quickly recall Sansui when stopped and asked to name high-quality electronics brands of the 20th century.)

Is the stereo worth the financial lift of getting it repaired and serviced -- detachable speakers, flip-down, knobs-hiding panel, digital tuner and all? It's up to you.

The audio and video quality of that May 2013 YouTube upload of the Sansui CP-7 in it were not great.

So maybe someone watching that video won't be convinced that one should spend good money on it. (Perhaps over a hundred times the three quid that you paid for it, depending on if you have the stereo shipped off to -- and eventually back from -- a distant repairer.)

But it's worth saving these electronics from the scrap heap. And it'll be fun to see how well a reasonably good servicing brings this frugal find to match a "New/Old Stock" or "Like New" eBay gem (same brand and model) selling for a mortgage payment or two. A repairer shouldn't find the job to be a nightmare: unjamming and rebelting the cassette-deck mechanism, applying suitable DeOxit squirts to the switch contacts inside the boombox, calibrating the tape deck's speed with a proper 440 HZ "A" note test cassette and with a frequency-calibration smartphone app', wiping down filthier parts, etc.

I say: go for it!

Yes it's one of the best sounding boomers

Be aware the speakers might need re-foaming

I've got one, they sound amazing. One of the best sound units in its size class for sure.

Highly recommended!



Rock On.

Rotten foams on the speakers are the sign of a good boombox lol.
Some of the best sounding boxes suffer from foam rot.

Are you in the UK Phil? I can help with repairing the cassette deck & tuner, but re-foaming is something I have never done before! I understand it's not too difficult - I tend to replace knackered cones with new speakers, however it is best to get the originals repaired!! I love Sansui boomers they are quite straightforward to repair :-)

I love mine!
The CP-5 and CP-7 are pretty rare.
You probably won't have to reform the woofers.
Mine has rubber surrounds and are originals.
The bass radiator looks like it might be foam surround though so check those.
Here is mine with a few pics.

Cool pics. Yes that passive surround looks foam.
I like how they mount from the outside instead of the inside. That's a more sturdy approach. The woofer is 5 inch maybe?

The Sansui literature says the woofers are 100 mm or almost 4 inches. :yes:
I took mine out of the cabinets and they have pretty large magnets too. :w00t:

Wow, they were pretty conservative with their measurements. I guess if you measured just the paper cone they'd be 4", but total frame width would be at least 5"

Yeah that seems correct. I didn't think they were only 4 inchers.

In good condition very, very hard to find. The transport can be released if you're comfortable opening it up.

I have a load of Sansui gear. Can probably answer a good deal of your questions too as I have the service manual.

Three quid is a steal.
