Hey guys,

I just powered up my walkmans after a long time of inactivity, the simple mechanical button activated models are working fine but the other ones with feaher touch are wobbling slightly on A side, weirdly the B side is ok, does anyne have any ideas to fix it?

Try a range of cassettes, a stiff reel may effect the power of a weak/small motor.

tried many cassetes, same thing in my aiwa px357 and panasonic sx75. The panasonic is very slightly noticeble but it's very obvious on the aiwa. Cracked the thing open but it seems like I need to de-solder a whole lot to get to the belt. I just wnted to try solutions that do not need me to open it up before going all out.

This is the panasonic, i just put it up for kicks.

check the belts maybe warped with a kink on it.Take the belt off and check the circumference is circulur.
the teeth of the capstan flywheel also tends to attract dirt in the gear,which could do with a good clean and pinchroller, hopefully stop the wow and flutter.Also note the takeup spool gear teeth may need a clean.

i know what you all mean...i try to get a walkman out of storage as often as possible and run it for at least an hour. i see way to many belts with sharp kninks in them not to mention all the ones that were round that start to turn to there new shape of oval. i really believe now that not running a walkman on a regular basis does alot of harm. even if they are mint i still run them...winter is really bad as the belts dry up faster when the furnace dries out the air.

The belt is perfect in physical appearence, the walkmans were not used for a while, i think the plastic roller is not gripping the belt as well as the metal fly wheel. I need to get a new belt but I cannot find belts for this model in part store.

hi..if you think you can get through that without messing anything up i would do this. get the belt out and measure it. they are usually square or round. go to turntableneedles.com. then go to the belt section which says "not for the faint of heart". they charge 3-4 dollars each and free shipping but you must have a minimum order of 2 belts. i try to order one the correct size and one smaller just because that is the error side for me. it's nice to have a see through ruler to do it. easier yet is to cut the belt to measure it once it is off the player...good luck if you try. that one sure doesn't look like a piece of cake to me.

wonderful site dude, i hope the belt size is 0.7mm(square type) i'll take it apart tommorow and measure the length of the belt.


BTW:- Great news guys, finally after 3 days, 5 battries and a bit of oil to the gears the panny is virtually wobble free.

I was just scanning through ebay and came across a manual for a feather touch style kenwood walkman, I didn't know that kenwood built walkmans unless of course if it's a rebadge.

does anyone here have the pleasure of owning such a walkman?

hi again..believe it or not i have one. it is a very greyish black color and in a very plain metal case. i didn't get any extras except the player itself. it should come with a remote and headphones but i did't get those parts. it runs only on a gumstick battery and works well except the play and auto-reverse are messed up. i have to start it and it wants to go to fast forward so i insert and remove the headphone jack 2-3 times and it goes into normal playing. if i were to put the setting on auto-reverse it will do the same thing which is go into fast forward until i do the headphone thing again and it slows down to the normal play mode. i don't even want to think about why this strange thing happens but it is a very usuable player as is. it's the only one i have ever seen in 3 years of watching ebay. it's just a crazy little kenwood cp-c7. anybody else out there have one ?

Hi there, it must be awesome to own such a rare piece, How is the volume on it compared to an aiwa, can you post some hi-res shots?

thankfully we just got a digital camera for christmas. i am just starting to get the feel of it. i am just on the chapter on how to get your pictures on the computer. soon i will get this camera doing all it can do. i will get some pictures up soon. i didn't know it was a scarce player although i have never seen another. it was on ebay and i took a chance for 14 dollars delivered on ebay. the sound is fine and it has b&c noise reduction along with base boost which makes for good sound quality. the volume is adequate but not excessivly loud. some of the old sony's can blast your ears off but this kenwood is not that loud. i think there was at one time a stand for recharging also. playtime on the gumstick is only 6-7 hours i would guess. not quite as much as some of the late sony's can do especially a sony wm-ex921 i have which seems to run forever.

oh k most of the players equiped with gum sticks are a bit on the weaker side. Are there any newer models with a loud range, the aiwas with the AAA batteries are some of the loudest I've heard, the older sony have better bass but I was never a big fan of the quality of sound they produce. They are built like tanks but sanyo and aiwas are leagues away in the sound department.

P.S The two sanyo walkmans that I have are post 90 and the mechanisms on both of them are from the panasonic RQ-V75 series but sound entirely different.

the 4 or 5 sanyos i have are back in the 80's and all are very good sounding and fairly loud. one of them which is an m-g4 has finally gotton to the point where it needs a belt badly. i haven't looked inside yet but with 2 speakers in the rear i am not looking forward to it. i hope it isn't one that is wired in to much. a few weeks ago i bought a small deal of 1990's realistics. without knowing anything about them i powered them up and was surprised by the sound. ok i just turned up the volume on one and it is loud+. it is heavy for it's size and i have come to believe some or all of these realistics were built by aiwa. this one is an scp-27 and is mid-1990's looking. it is made in singapore for radio shack. it even has a push to open door latch. the 3 i bought are just a cut above anything i have from the 1990's except a couple of high dollar japanese players but they are far from what i would call loud. if you bump into a 1990's realistic give it a listen and you will be surprised as was i.

Looking by the picture of the Aiwa, there mightn't be any screws holding the main board down-so if that user wants to replace the belts/other parts, they will need to remove the solderings.

got one, too...

also a cp-3 and cp-5 (cp-3 - a.k.a. some Sanyo or even Grundig, cp-5 a.k.a. some Toshiba, cp-c7 a.k.a. some Aiwa, Grundig etc.)

On the Realistic Walkmans I spoke with Radio Shack owner in town weeks ago when in for AC adapter who has worked for them 35 years now owns store here. He said that late 70's early 80's AKAI built cassette walkmans for some of Realistic models and also Reel to Reel units rebadged built by Akai. This relationship ended I think he said in 84 with batch of Reel to Reel's that Radio Shack dumped for $300 and it cost them $450 to make. Owner distinctly remembers the reel to reel was great quality retail over grand. FYI

sure enough...if i put the kenwood cp-c7 next to an aiwa hs-p202 there is alot of similarities. both even have a smoked glass viewing windows. to bad though, the aiwa has a sound problem. it has a load humming noise that goes right up in volume as you turn up the music volume.

Can anybody post hi-res shots of the kenwood and aiwa for comparision.

I have a Sony WM-701C and Panasonic RQ-S75 that both in one direction play correct steady speed in other direction noticable but not bad wow/flutter or wobbling sound. Do I read correct that this is a belt problem if so anyone know how hard these are to replace? thank you JOHN PS have not taken a player apart yet. Picture of the two models.

you have to de-solder the pcb and replace the belt for the panasonic, for the sony, you can look at the service manual from the link posted in the service manual thread.

You were totally right about the kink dude, The belts have a very bad kink and it's affecting only the plastic fly wheel for some reason, I temporarily put a sony's belt on both the walkmans, both are playing flawlessly on both the sides. I think both of them have rpm sensors as although the belt was considerably tighter as it was shorther than the originals, they played at normal speeds.

Im going to buy new belts for the players in a few days.
