This is quite a long video, but I thought it might be of use to anyone that has one of these or something similar. A friend of mine asked me if I could take a look at what can only be described as an outstanding Boombox from the early 80s. In this video I sort out the cassette deck and do a quick look over while I was at it.

I was shouting at the screen the first time you took it apart “Change the feckin’ belts and pinch roller!” 🤦♂️
I also had a feeling your test cassette choice would be the Thompson Twins - Quick Step & Side Kick 👍🙂
I know should be all or nothing! haha and I have more than one copy of that Cassette. This is the only i keep for testing as its had a few chews over the years haha!
It’s a1978 model. The last of the premium models towards the end of the 70’s.
hello , I'm still struggling with putting that small pinch roller , its so tight. did you remove the copper fit , on top? or you force it in that small hole ,? thanks . desperately needed help. thanks.
Hi! I have a sharp gf 9090, which I believe has the same cassette mechanism as the 9191 one, and my problem is that when I press pause, the cassette tape still goes on. I have took it apart to have a look at it, and it seems to me that when I press the button, it doesn't pull the idler wheel away as much as it should, so the tape is still being driven by the motor. Any advice on fixing it? My idea is that I have changed the idler and the capstan rubber which you have replaced in this video, and maybe it's a bit bigger than the original one. Moreover, the auto stop system doesn't work at all. Thank you in advance!
Hey guys
can somebody help me.
I recently found one on my grandfathers attic.
I put in some new batteries but it won't work. I have absolutely no clue about that thing but i really wanna get it to work.
A remote diagnosis is definitely difficult but I would be happy about any help. Thanks ;)
Well it will certainly need a clean certainly the battery contacts then you might get something out of it like the radio but the chances are all the belts and so on on the cassette deck will need replacing. And then all the controls will probably need cleaning as will the big switch on the circuit board for record and play
Thanks for the video i will now replace the belts and keep it in my mancave
Great stuff
Thank for the great video and explanation. Recently buy a 9191 HB ,defective for the moment,lots of mechanical issues no ruber belts and more...
i will apreciate if you share the dimensions of the ruber belts at least the flat one from motor to capstan.
Thank you in advance.
No Idea I just bought a set.
Hı my have sharp9191 record button dont working plase!help
The first thing would be to make sure that the lever is aligned up with the switch on the circuit board and that the circuit board switch is cleaned
The keen eyed will have noticed 11 September written on the sticker of the motor of this machine at timestamp 23:49. It's successor, the GF-9292, was well into production by August 1979, which suggests this machine dates to 1978.
Well spotted
How do you tighten the handle on these? Mine has come loose
Hey BiGuP & thank 🙏 I hope to bring mine back from the grave on your tips and confidence you’ve given me.. Cheers again boss
Good Luck
Hi mate, I've recently found one of these in my grans attic! (gf-8585) it works amazingly, but just one problem... the left hand speaker only works at low volumes/doesn't work at all. any ideas?
Id guess clean the volume and balance sliders with contact cleaner first
done that now, still no sound coming out of the speaker unless its at almost zero volume, could it be a problem with the pre-amp? Thanks for your help!
Great unit sharp made really nice units in the boombox Era, glad i watched this video i was working on a sanyo m9970 and after taking it apart and changed the belts the keys were frozen, i saw you moved the plate , and the keys began to function, do you think i should move the plate around and solenoid ,don't wanna trash it 😢, any help would be greatly appreciated, looking forward to other restoration videos
Now that i found this video, i decided not to sell mine but replace the belts and listening to my old tapes!!
That Makes my heart glad
Well u know how to Sort man I've got one Hitachi smaller same era but took certain bits apart but certain rubber belts- (drivers) stretched or keeping in Dampish areas so now sitting in outhouse Ile send to you if you can get needed bits to bring back to life Radio& Speakers fine ..
Sadly I don't have much time for any new projects at the moment.
@@MatthewNorthMusic ok I may ask again when your not so busy .
Enjoyed this video thank you. I have the sharp gf 9090c
Hi! Where do I get a hold of this idler tire for capstan at 8:43?
eBay
Great vid well done 👏 it would have been in the bin by now 😂
No never do that esp any boombox from before the mid 80s.
I hope you don't charge by the number of times you took that thing apart, lol.😂
Lol

Glad it was helpful!
*Promo SM* 🤭
Phew, ten out of ten for perseverance Matthew. Well done.
Thank you.
Great video and nice boombox ! , the capstan is massive for a portable .
Big is best :)
The GF-555 and GF-666 have large metal capstans and sound good with powerful speakers, compared to the later models that have cheap, flimsy plastic parts and tiny speakers. The GF-9191 featured in this video is one of the "beef-eaters" of the early '80s boombox era.
