My Kenwood CP-G5 and its mysterious missing part(s) [picture-heavy post!]

awm - 2010-10-06 06:29

Hi,

I've been out of this whole hifi/stereo thingie for quite a while (more than a decade, actually, strange story, please don't ask) but recently rediscovered my enthusiasm for everything that records and/or plays music.

The other day, I pulled out my old Kenwood CP-G5, which was actually my first 'Walkman' (ca. 1985), and I liked it a lot, even though I never used it very much (wasn't a big headphones type of person then, and in a way, still ain't). It was replaced by an Aiwa PX101 some years later, and basically sat in a box until now.

Here are some pictures of the device (pics 1-4), which I still consider quite pretty (I usually like that a-bit-of-understatement design, and compared to many other mid-80s machines, this one is not too show-offy).









After I had pulled it out, I noticed something weird (you maybe already noticed from the pictures above): The cassette door wouldn't shut correctly. I didn't remember it being that way, and by my cursory inspection it seemed like there was something missing, as the 'Open' knob wasn't there, and there was a door lock latch missing its counterpart. As to my recollection, that was never a problem, and so some parts seem to have got lost. Very strange.

Given that the unit never left that box for ages (a very big and convoluted box, I might add), the missing part(s) should still be around somewhere. But I have no idea what exactly to look for. Maybe someone also owns this unit and can give me a hint.

Pics 5 to 9 show the evidence. Pic 5 is the cassette door at full width where there probably should be something (some kind of metal bar?). Pic 6 is the side with the empty slot for the 'Open' knob, and the inside area. Pic 7 shows the part of the cassette door where there should be some closing mechanism, and the orphaned latch (which is also picured in pic 8). Pic 9 shows the empty 'Open' slot, and the sorry state of the non-closed cassette door as-is. I have no idea what the remnants of adhesive tape that are shown in the pictures might mean.

Does anyone else have this machine, and/or can point me to what exactly is missing here, and what I have to look for?











BTW:
(1) Does anyone happen to have a service manual for this device? This little machine could use a little servicing.
(2) Is there anyone who knows who actually manufactured the unit? AFAIK, Kenwood usually bought their portables from other manufacturers.

As an aside, here is another picture, which shows that there has been some leakage from the batteries, which unfortunately hadn't been removed. As the battery compartment isn't fully accessible, any ideas how to clean it without tearing the whole device apart?

Welcome to our forum and very good up close clear pictures ( WE LOVE PICTURES ). I have a Kenwood CP-G5 like yours and the latch assembly came loose on mine also. This model came with a FM tuner module that the radio was inside a cassette case. Very unusual rare for a tuner module is inclusion of LW band 160-260 kHz which this Kenwood has. ALSO unusual the Tuner Module was MADE IN FRANCE !! I have the original Tuner Module and the unusual material case. This is certainly a more rare model especially with tuner module. You are right Kenwood often used other companies parts and put their name on them. I believe the tuner module and probably many internal parts are from Toshiba. A note my belt had turned to complete goo a difficult mess on the pulley's to clean. You can buy at autopart stores Battery terminal cleaner that neutralizes acid. Probably remove the back plastic part of case and will expose length of battery area so you can clean. Hope you can find the latch assembly as parts for most Walkman are just not available.
I certainly agree with you that the exterior design was striking yet not overstated or flashy like so many mid 80's Walkman. Having a FIVE BAND EQ is also fairly rare on Walkman as most had 3 or 4 bands. Glad you kept it safe hidden away.
I do not have a service manual.

Hi John,

thanks for the welcome and congratulations for having the tuner module. A very unique design. I've never had or even seen one of those (not even a photograph), and I always longed for one back then every time I laid my hands on the little player (esp. since it is specifically designed to accomodate the tuner add-on, and the casing isn't even completely closed for that reason). It just seemed incomplete without it.

As for the latch assembly: Thank you very much for displaying it. A part like that would explain a lot. Weird that I can't for the life of me remember ever having seen such a thing. Maybe my CP-G5 was constructed a tad differently? I have no idea. OTOH, me not remembering the part may as well be due to ageing and dementia... Smile

A part like this would, OTOH, explain those remnants of adhesive tape all over the place and some scuffs (BTW: if they really assembled the unit with adhesive tape, that would be a strange way to do).

Could you post a photo of the back of the part? That might give me some additional clues.

P.S.: I have the same carrying case as you do. I always wondered what the outer compartment was good for. Now I know... Smile

Glad to be of assistance. My unit is at a fellow members having some capacitors replaced and waiting to find a new motor one I have is weak but plays almost right on speed. Am unable to provide any more pictures other than what posted for many weeks or longer.

Thank you.

I don't think it's a Hitachi. While the use of a tuner cassette may point in that direction, others, like Toshiba, used tuner cassettes as well.
In the meantime, I managed to spot the very same assembly of drive buttons (Reverse, Play, Stop) on Toshiba's 1984 KT-AS2:

So I'm inclined to believe that it's actually been manufactured by Toshiba.

HERE YOU GO a original KENWOOD CP-G5 SERVICE MANUAL ON EBAY
Item number: 200494987729

Would greatly appreciate if you could scan and send me copy of the Manual so I can do further work on my CP-G5.

Thanks. I probably should, however, find that missing part first, before throwing additional money at this issue. Chances to buy the part itself are probably zero.

i can asure you all, it IS actually a Tosh...

Greetings all;

This particular model KENWOOD-Trio is based on Toshiba mechanism but it's design and Features are Unique for this KENWOOD. I believe it was made in collaboration with Toshiba. this was only in the early years of the Walkman age.
Toshiba themselves don't have a similar Walkman like that in design and features.
However AIWA OEM for KENWOOD are plain AIWA in features & Design except the KENWOOD name and it's very obvious.

If you interested of selling it as-is please PM me.

Hello again,

 

have been away from this forum for a while (how could I dare?), and can gladly report that - by pure chance - I did find the missing part a short while ago. No photo, sorry, but it's exactly the part in John's photo.

 

Unfortunately, I let the chance to buy the service manual back then pass by.

But there are two on eBay atm.

 

I'll get one and can send scans to anyone who needs them after I received it.
