- Hi Folks,
Here's a Sharp radio cassette recorder that needed some work. Dirty, intermittent controls, lack of radio reception, and no cassette drive. One problem led to another, so join me as I tear it down, clean it up - and work around the idler tyre, capstan rubber and pinch roller issues. A labour of love, but I didn't want to give up....

Thanks very much for your support 😊👍
Your work is interesting, wonderful and very useful
Thanks for watching and taking the time to comment 👍📻
If collecting o rings becomes a thing your well sorted, fantastic stuff love the vid .
Thanks for watching. You can never have too many O rings 😁👍📻
Very informative and I look forward to the next nice edit on that 8080 refurb', out of my league but always enjoy learning.
Thanks as always. Hopefully sorting this will give me the parts I need for the bigger 'GFs' 👍
Great work :-) definitely a lot of improvement with the new pinchroller. However I could still hear a lot of flutter in playback even at the end of the video. These machines are definitely meant to have more stable playback than this, I reckon it is the tubing that’s still throwing it off a bit, I bought the replacement tubing on eBay specifically designed for this machine. Or I think the tubing a lot of people use is RC fuel liner. Another trick that apparently works well is to put layers of heat shrink sleeving around the capstan till it’s the correct diameter.
Thanks! I agree, it's not ideal - but that may be the belt, or even still the roller, which seems good but is ultimately a repacement from another machine. I'd be interested to see how much run-out you had with your capstan bush. The main issue is that there is only a 1.5mm wall thickness, so any tubing of the correct OD and ID will still 'cam' - that is afterall why there's the sprung loaded take-up mechanism to accommodate it - as the extrusion process is at it's absolute tolerance limits at this point. Just 0.1mm off-centre on the hole gives 0.2 runout, and at that RPM it's going to start bouncing quite nicely...
My original tubing should in theory have been OK, and I looked at RC fuel line as an option before I found the other stuff (which I bought in the hope that it was made (or at least QC'd) as well as the picture in the advert), but the RC line would still ultimately suffer the same tolerance issues - it just happens to be available in the correct ID and OD combination, which is why it's an available option.
I have some other GF's to work on, and I'm hoping at least one will have an intact bushing so I can observe it's behaviour - but I fear they may have turned to tar, as it such an age dependent. Gotta love the old machines 🤣
Thanks as always for watching - greatly appreciated
👍
I used a pipe cleaner for the capstan bush and chrome polish for the corroded flywheel (works great).
Orderd a , non 3D printed, plastic spare part on ebay. Replaced the pinch roller with a new one.
But the sound of that thing is rubbish. The speakers are not very good.
Thanks for watching. Good idea about the chrome polish. I've used Ali polish in the past - similar result I guess - cleans up without being 'too' shiny. Great that everyone works things out differently. They aren't the best sounding GFs, but I still wanted to save it. Thanks again 👍
I had a GF6060E (and still have) & it has been an absolute workhorse, the only difference appears to be the lack of silver knobs, & SW2. the Z at the end of the model number indicates it was not originally sold here in the UK. as far as I am aware, the Sharp numbers with E on the end were UK/Europe based
Yes, the 6060 was similar to the 6161 (such as the GF9090/9091) - I think newer model year with a few updates.
The 'E' were European models, as you say. Not sure about the Z to be honest. The JVCs use different model suffixes (which I know a bit more about because I collect more of the JVC stuff from around the world). I'm looking to get a GF-6060 in to see if the mech is same as the 6161, with the capstan bush, etc. Thanks for watching!
I love your videos, but I have a question. How come the sound of your microphone is always a little muffled? It kinda lacks the higher frequencies.
Thanks for your continued support, and for your question. Short answer - I'm unsure - I edit the video with decent headphones and the sound is genuinely much better on the raw footage. I notice the frequency loss too (even on the music) when I see the uploaded version, so it will be something to do with the compression for upload. That being said, I am looking to invest in improved lighting and microphone (maybe even a better camera) later this year. I'm a little tied, as I actually have 2 UA-cam channels, with the best part of 3K subscribers, 600 videos and 620,000 views between them - but I am yet to earn a single penny from any of it. On average, I spend around 10 hours a day on this channel, and want to continually improve - but I was rather hoping I would be able to gather some financial contribution to help it grow. I'm super-excited about this channel though, and I have so much to come - so watch this space and I'm sure it will become even better soon. Thanks again!
you can buy new boom boxes ,there one brand called studebaker cd and cassette player
Great presentation. Audio needs improvement. Mic is jarring.
Thanks for watching. Yes - there's something going on with the audio when it uploads. I'm trying to get to the bottom of it.
Once again enjoyed the work around with the tubing and pinch roller fix, interesting little wobble could so throw you off the scent, well done again, unsubscribing due to the bad music, seriously , you don't need plebs like that, learning tips and tricks is worth it. Joe
😂Thanks as always! I might kill all but the intro music from now on. I think my subscribers seem to prefer the sound of screwdrivers instead 😁👍
I'd watch these videos with interest were it not for the awful music. Unsubscribed.
Thanks for stopping by anyway. A lot of people don't care for silence when there's something happening on screen that needs to be shown, but there's nothing to actually say. And we aren't allowed to use music that is commercially available. Anyways, thanks again for stopping by.
@@retro_restos There's a huge amount of music available in the youtube audio library to use.
@paul1153 yes there is, but it's a retro repair channel - not Spotify - there'll always be personal preference. I value my channel community highly, as they are overwhelmingly enthusiasts, ex sales, repair or collectors, so the minority that judge 50 hours of work on whether they like the music can come or go as they please. I'm always looking to improve the content as far as finaces allow (e.g. I'll be investing in better lighting, audio, etc soon), but the music is not what genuine followers are here for. Although I might add that I've had some commentators say that they love the music...
