Hi everyone-I need some help on this:
My GF-9595H is playing a little slow and it doesn't rewind.
Well I have it all apart and there isn't anything wrong that I can see for the rewind.
It engages the thing but there is no rewind at all on the left spool.
Now all the belts look totally fine.
I'm cleaning up the motor tomorrow and all the mechanisms-I ran out of cleaner.
I'm sure all belts are there and in decent shape!
After I clean with tape in play as I can check speed(hopefully this will help).
But the rewind does baffle me-no belts missing but something isn't engaging or ??
The most important thing now is the play speed.
I'm hoping after the cleaning tomorrow that will help.
Has anyone worked on one of these?
I have the back off and the whole thing pulls out to-kind of neat.
I did have to pull off the circuit board and move it to the side to access all cassette belts and mechanisms-Not to bad.Just concerned about motor-is it adjustable?It's probably dirty.
Let me know any tips of info-it would be greatly appreciated-GB.

the 9696 is simular but do not remember about the rewind some have a square belt on a small wheel you can un screw the front cover and take a peek and look carefully

check the tyre idler on the capstain. it always gets worn away on these models . . look for the rubber around the capstain , you will see if it is worn.

most likely the idler tire will look like this

it's a common defect on the GF 9595 / 9696

it should look like this

It the capstan idler tire is nothing but black goo, you can use silicon fuel tubing available at R/C Hobby shops.

happy birthday fatdog and yes i did the rc fuel silicon tube replacement and it works real good just have to cut the right amount not to big not to small

Hi guys-Yes my idler wheel does look really worn like that.
What does this have affect on? Does it make it go slower or does it not want to make the rewind engage?
By the way-had the front off also-can see that the ff has a belt on the front.The rewind does not and there is no belt wheels on the side on the front so there is no belt for rewind on the front.
I'm getting my cleaner today and I will let you guys know by tonight or tomorrow what's going on after this.
By the way how do I fix this idler wheel again-silicone?
I'm not sure I follow.
I really appreciate all your help so far on this-GB.

In play mode , the rubber roll on the capstan makes the take up idler turn. If this rubber thing is worn , the tape gets stuck everywhere.
It also makes Fastforward and Rewind work.
It's essential for good functionning of this tape deck.
A very bad design of Sharp but easy to fix

Some members here use Silicone tubing (used in remote control cars for the fuel)
I use Hama beads with heat shrinking tube around them( works like a charm)

and the belt you mention is probably the belt for the tape counter

it a process of removing the capstan wheel notice the pic of wheel touching that rubber tire you have to cut a piece of silicon fuel tubing that you can get at a rc hobbie shop,then once you clean that little window where the tire sits mine became goo so i had to clean that sucker real good,,make sure when you are removing the capstan wheel from behind make sure you do not lose any springs or plastic parts that they do not fall out of postion as you pull that stuff apart,,the tubing should be the small diameter one you will have to test slipping a piece on the shaft to make sure its not loose,, when you cut it..it should not be to big or too small i cut one two big it kept on jamming then i cut it to short and it worked for a couple of seconds and when all the way to the bottom,now if the tire that you pull out is still intact then i would cut it to the same size,the rest of the process is to put the tube inside that little window push the the capstan shaft untill its though the tube it may try to push the tube out with a little patience and the finger in front of the little window once you get it though just turn the capstan and see if the tube is not jamming os slipping downward it should stay toward the middle that why once you press play the wheel makes good contact and that my friend should never give any other trouble for at least the next 3000 years

Hi ramon & everyone here:The tire roller for the capstan looks good-the idler wheel that's on the back is pretty worn(it's against the big wheel on the back).
I probably can take this off without too much problem.
I put it back together tonight after a serious cleaning.Tape is still slow though.

Just noticed:When you first start the tape it seems to play at the right speed and slows down right away!
It seems as if the speed is varying when I play a tape.
It seems to slow down a bit but then seems to speed up a little at times.
Could this be the little wheel on the back that goes against the big wheel on the back that spins everything(it's not touching anything when in play mode)??
I'm confused-if I replace the tire thing I wonder if it will fix the speed?
My guess right now is the motor?
Slowing down and then speedinmg up-Hmmm.
Any more suggestions on this.
I love this stereo but the tape deck needs to work.
It's funny about the speed varying like this and also when I start it up it seems to be at about the right speed.
Belts are all in decent shape-no slipping.
I'm listening to it right now.
I do really appreciate all of your guys help on this.
I will replace this wheel later this weekend when I take this thing apart again.
Thanks guys-GB.

Hi-I noticed one thing: If you run the APLD and when it starts on the next song-The speed is o.k.!! Then it slows down right away.It seems the more I run the APLD it sees to work better.Motor is slowing down again!.
Could it be the motor??
I'm guessing it's not the wheel.
Just giving you guys more to go on.
I'll run the APLD a few more times but it does seem to slow down again after this.
Thanks guys-GB.

It's getting somewhat better as I use it.
This thing is lighting up like a Christmas tree-I pulled the ant's all the way out and set it up for FM reception and now the FM Stereo & Tuning lights are staying in which is way cool.
Now if the Power light will stay on.
It just needs be used!
It's old and I think the poor little tape motor might be dying-It sounds this way slowing down and kind of speeding up.
At least now everything else is good.
Anybody else on this??
It's a super stereo-just need to get this cassette issue worked out.-Thanks tons-GB.

OK-I really think you guys are right-just noticed the tire wheel in front adjoining to the capstan-was watching it in play mode-ireggularities in wheel.The rubber looks somewhat good but I do think the wheel is out of round.Making it sound funny and making it not right.
I will get to these in the next week.
I do think with replacing the rubber on these 2 wheels that I found might do it.
As far as the speed of the motor-could be restrictive also so who knows.
I will let you guys know how it goes when I tear into it again.
Just noticed-The rubber interior of the capstan itself is worn with irregularities.
Yes-the rubber roller is good-The capstan itself rubs against the wheel-well the capstan's rubber interior is badly worn.Can these be found and can they be replaced without too much hassle??
It seems after I've cleaned this off the speed is getting better but this thing has to be replaced.the rubber roller wheel that goes against it in play is like it's on a bumpy road!
This may be part of the whole problem-GB.

Yep, my 9696 has just developed the exact same fault, gotta tackle it at some point

Hi everyone-Now get this: The speed is pretty good after much cleaning and some tapew operstion(use)and the sound is much more smoother.
BUT-This is crazy-if the volume is low-like 1/4 volume or lower the speed is almost normal-very close to right.
BUT-if you crank it up on cassette the speed slows down!!
Now this ought to be good-very challenging.
Power supply,bad motor,what??
I'm confused-The radio is totally fine-it's the cassette-I'm not sure what to say now.
Help!!
Have a super Happy New Year-GB.

I would check the power supply.
Seems that the voltage it delivers is not enough anymore.
My guess is that the capacitor of the power supply has had it.Dry caps are normal after 20 - 25 years

Yep , although i had many issues with my 9595 , i stil love this one.When i bought it it was 100% non functional but the shape was near mint.
Thanks to other members here it's 100 % functional now.I replaced the power supply capacitor(C507 3300µF /25V) with one of 4700µF , just to be shure.
You can find these in any electronic shop. Just be shure to buy one with the same distance between the 2 leads. This looks the best AND solder the new one in with the right polarity.

IS SOME ONE HAVING PROBLEMS WITH A GF 9595?????

All problems can be fixed, right Eddy, Ramon????

With time you will be happy having spent time on it! Just take your time and put some love in it! And DO listen to all these guys!!!!!!!!!!!!!!

Good luck...

Hi everyone again-I do appreciate all your help.Eddy-I'll look into getting that capacitor.
Is that the only one I will need? Going to check my voltage output on cassette and then on FM to compare outputs but I think it is a power supply issue with the tape slowing down like that. Need to invest in a small soldering tool also.
Also not to be dumb but could anyone show me a photo of the power supply capacitor or the right area to look into?
The cassette is the only thing slowing down when the volume is up.It doesn't do anything other than work perfectly on radio.
I appreciate all you guys help-GB.

Sounds like things are covered.......

Right on Brian , almost anything can be fixed
That's why The GF 9595 is still my favourite box.
Hard work but so rewarding. So your 9595 is still going strong , Brian?
GB i will post a pic of the power supply later today. I would start replacing that capacitor.
The others may be just fine

OH YES Eddy! Oh yeah!!!!!

But....... Still need a silver bat. door for my silver 9595....

So it wasn't you that bought the Silver 9595 on Ebay.de a few days ago. I believe it was 49 € BIN

Yo Ghettoboom. Here's the picture with the location of the power supply cap
]

Hi Eddy-Thanks for that!!
I'll check into getting this capacitor within the next week or 2.
I'm not near a electronics store right now but I will be doing this when I get the capacitor.

By the way it doesn't work on batteries.
I'm looking into that tonight.
It pops once in a while when the batteries are in there even if the power is off.
I was hearing this little pop over the night and was wondering what in the heck-It's the 'popping' boombox.Also-my power on light doesn't stay on-when you power it up,it comes on briefly then goes out.Even when the a.c power is on and it's working it doesn't stay on-just a note.

So I took the batteries out until I can see what's going on with the dc power.

Thanks again Eddy-I'm sure I'll get this going.
Is there anyway to test this part or just check the voltage on this power supply?
Thanks again-GB.

I tested the voltage before i closed the box.
I believe the voltage was just a bit under 15 V DC.
There are meters to test capacitors with.
They are called ESR testers
The usual capacitor meter in a multimeter is NOT the right way to test capacitors by the way

A ESR tester like the one a bought a few years ago
Peak electronics

Nope.... And I will not be buying for many weeks, months or years now.... All set I am with my colection!!!

I will only be hunting down the parts I need!!!!

Voila!

yes the sharps are a joy to work on...

Most of them are . Changing belts in a 777 is a bit harder though

Ehhhhhh..... Not hard, but...... Just, well, longer.....

Hi everyone-Further info on this unit:
Well if you crank up the power on the radio I find that it turns out the stereo and tuning light s and distorts pretty good-Has to be power supply.
I'm going to get my tester in there later this week and test this thing out.
Also-I noticed that somebody has done some work on this unit before-By the power switch voltage selector there is a switch missing and I noticed that the wires going to the voltage selector have been cut-onlt the 110 side is hooked up it looks like.
I have cleaned up everything but still no power on batteries.
I'm going to take some detailed photos of the parts I have in question-I first want to get the proper voltage out of this thing then I can tackle the battery problem-think they're related?
It still pops if it's plugged in-switch is off-the power light is coming on and it's trying to turn on-wierd!! Switch is probably dirty-cleaned them all though! No it's better with firm switch off.
This one is a serious project!
Thanks guys-GB.
(Photos soon on the board and the capacitors when I tear into again.)

Ahhhhhh..... Souinds more like a human is at fault and not Boombox age!!!!!! Interesting! Get those pics on here so all can see and help!!!!!

I wish that some of these week-end woriors would not put there hands in to Bboxes!!!!!!! Look what they have you doing!!!!!!!
