80's HITACHI TRK-8190W Boombox Cassette Belts Replacement

This is a HITACHI TRK-8190W, A 80's holy grail boombox. It was kept in good condition except the cassette deck. One of the main flat drive belt was melted away. So I replaced all drive belts and cleaned inside out.

I always enjoy watching these restoration videos. It's like giving them a new life. As always, great video!

Hi, Miguel. Thank you for your compliment on my work! I'll upload more videos so enjoy them! Thank you again.

[@Sheffield_Steve]

Just happened upon this restoration after 4 years since it was done. I wish I'd have been able to save pocket money for a ghetto blaster like this in the 80s. Great restoration, looks brand new, you would only need to pull it of the original packaging to fool me!

[@VytautasAkulavičius]

With the help of this video i replaced all the belts on my TRK 8190E without any problems. Thank you very much sir!

[@markpointon2126]

Hi can I ask where you got your belts from thanks

@@markpointon2126 Hi. I just ordered a bunch of different belts and then replaced them by comparing with the old ones. You can get such belt sets at Ebay or Ali for cents. Cheers

I have the 8290 stripped down on the bench now. Only the long flat belt is in one piece, the others are goo. Surprised how different the mechanism is to the one in the 8190. Your video has given me a number of Pointers though. New belts ordered from the USA.

I like Hitachi. I just aquired a new in box Sony MHC 3600 mini system. The duel tape decks need new belts and pinch rollers. I found the cd player had a delayed power up. It had a leaky cap. I had to replace it. But the cd player is still taking a minute to power up. I think it was stored in a hot climate. Rubber speaker surrounds are still good though. Another great job Teddy

Oooh! So this is THE Hitachi you mentioned on the other video. I can see why you decided not to mod it. It’s a total peach, what a beauty! I only question that “18w” on the front. That’s quite a bold statement. Other than that, very neat equipment. Nice tweeters, too.

[@teddyhashee]

Yes, this is the HITACHI that I was talking about. I just wanted it as original state as possible. The end of the restoration it shines like new. Hitachi TRK-8190 was 16W, but this model this 8190W is 18W. Massive sound.

These are very well-built, and loaded with features. It's too bad Hitachi quality started to decline 2-3 years later.

[@teddyhashee]

Hitachi is a famous company with its motor. Hitachi made many appliances but not much audio electronics items. So that makes Hitachi boombox so rare and precious. Thanks for the comment!

[@80s_Boombox_Collector]

They also made many transistors used in other brand boomboxes.

[@Aetila]

I wonder where you can buy flat driver belts for Hitachi boomboxes? I only see simple "round" belts on Ebay in packages but not those flat driver belts. I want to know it before I buy a Hitachi renovation object.

[@RodrigoVolta]

Whats the products that you use to polish acrilic and chrome parts? Thanks.

[@teddyhashee]

I use goo-gone to clean the whole plastic body. And I use plastic cleaner as well as chrome cleanser bought from Japan. The company name is Soft99 www.soft99.co.jp/english/

[@cassetteaudiostilllive611]

your restorations and your videos are all very very beautiful and interesting, I love to watch even the longest ones in full! if I can afford it, you should make an even more accurate check of the recorder, not only in play mode, but also in rec! in this boombox, in fact in play mode the left channel is very very weak, it seems that only the right channel works, also observing carefully in the meter and this has also happened in other videos

[@WalkingPez]

Impressive attention to the details.....everything made sense to me except 6:35 to 6:50.....were you de-magnetizing something, by chance? I'm preparing to recondition my father's TDK-8290H

Buna ziua! La acest model, care e cauza derularii casetei cu viteza fluctuanta? Multumesc!

[@hemiolabooks450]

Thanks Teddy for putting this up! You inspired me soon after to take apart my old TRK 3D2 and finally take the plunge on these machines. Two questions if I may: what is the spray you use at 5:40? iso alco? The other thing I'm not sure about is whether the plastic gears should be greased at all. It's hard to tell after 32 years whether the factory did 'em or not? All I know is the mechanism is sounding a little noisy these days. Anyway, great job.

[@teddyhashee]

Hi, thank you for the comment. I used rubber rejuvenator to clean and restore the rubber parts. amzn.to/2KrnJoL Some gears need grease, some do not. When you clean these parts, you see that original grease is there or not. Mostly they used black color grease and easy to locate them. If you see the residue of grease, you want to replace it with new grease, if you do not see them, you do not have to.

I have a Sony tape recorder made of Japan, but the sound is very low, ears have to listen very close, so much IC is bad or something replays please

[@adrianfox9431]

Great video. I "restored" one of these recently as an amateur, but I think one of the belts I got in the kit, wasn't correct as it doesn't take-up when the reel gets heavy with tape. Also, I broke the solenoid for the music search system the auto stop doesn't seem to work and when I record the sound is very faint, not sure if I caused these. None of these are deal breakers apart from the weak belt. I'm nervous at taking it apart again.

[@teddyhashee]

There are many factors that take-up reel does not work well. If the mechanism include the drive tire ( not drive belt), then the tire may worn out and it may be causing the slipping. Anyway, I always do the re-open the body and re-do the work as many times as I need to. If I need to re-do the process, I will do until I solve the problem. So you do what you have to do in order to bring your precious boombox back to live!

[@adrianfox9431]

@@teddyhashee Thanks for the encouragement, I'll have another go with a finger on the take-up spindle and see what is slipping. Did you have to un-solder anything as part of your strip-down? I struggled with the tape mechanism as it seemed to have wires soldered to the main board that I was reluctant to de-solder so I couldn't dismantle it to the extent that you did. Any pro tips on fixing Auto-stop or recording level? btw, I now have a Sharp GF-9191 on its way that I'm going to attempt to restore as well. Once again thanks for the video, will give me more confidence now with my unit.

[@teddyhashee]

It is depends on the wiring, if it is too short wire to clean the cassette deck, I de-solder the wire, or just cut them in half and later I connect them by soldering. There is no easy way to fix the auto-stop or such a common problem. You need to observe the cassette deck each parts, and need to locate which one is causing the problem. Remember, restoration needs your patience and great amount of time, need to observe from top to bottom. You can do it.

[@adrianfox9431]

@@teddyhashee thanks again, I now got the cassette working okay but this unit seems determined not to let me win. When I put it together for the final time I noticed that the radio (now?) doesn't receive stereo FM (the light doesn't come on and the sound is indeed monorual) :(

[@neiloliver7950]

Teddy, I have just finished restoring 8190E and 8290E models. Your video really helped my have the confidence to dive in. I am now working on an 8190W (same as yours) which has the dual voltage input, no LW but two SW. I know there was also an 8190H. I think E was for Europe, H for the US and I guess W was for Worldwide?? Do you know? Thanks Neil

[@teddyhashee]

Hi, Neil. Congratulations on your success restoration. Here is a info about 8190. "The TRK-8190E model, shown below, was sold in Europe, and is set for 220 or 240 volts. The TRK-8190H model was sold in North America and is rated for 120 volts. The E model has a black tuner dial, while the H model has a brushed aluminum dial. And there's another version called the TRK-8290 Perdisco, which has all the same features plus the ability to play a wireless FM microphone." From www.wikiboombox.com/tiki-index.php?page=Hitachi+TRK-8190

[@hunterwells3410]

Hi Ted, firstly thank you for making the video (whether it be from my request or coincidence). I'll probably watch this video half a dozen times over while restoring mine. I have a couple questions as well... the first, what do you use to polish the clear plastic (tuner windows, cassette door windows)? Also, mine has some sort of electrical issue it seems. When I turn on the radio, the sound quickly fades to nothing. While doing this, the led meters either flash randomly and flicker, or they simply shut off.... What could these things be due to? Also, sometimes when i turn it to radio, i can her popping in the speakers.... Any idea what that could mean? Thank you in advance for any info/guidance

[@teddyhashee]

I used plastic cleaner from Japan www.soft99.co.jp/english/products/carcare/body_cleaner/plastic_cleaner.html?pid=09066 However, you can use any other plastic polish products you can get from Amazon, eBay amzn.to/2FUqZaY Here is my video that I tried remove scratches from plastic lens on the clock. It may help you. kzbin.info/www/bejne/o5XIiYmOoZ6ci5Y If it is deep scratch, then you need to sand them down to remove it. Some of my boombox video, I used water sanding to remove most scratches from lens, but it will take a quite time. If the only radio has problem, but cassette deck plays well, then it is not from the power supply neither tuner/amp themselves. Rather I guess from selector switch connection. Did you clean the selector switch with contact cleaner?

[@hunterwells3410]

Thanks Ted, and not yet I haven't, I'll have to get some contact cleaner soon.... And also, it does the flickering and popping/fading/tuner lights dimming while switched to tape too.... When i got it, the deck worked but the belt snapped as I was playing the tape.... (also, can you remember the belt sizes by any chance?)

[@teddyhashee]

I did not record belt size, sorry. You can test different size of belt to find out best fit one as I always do. After that, you need to adjust motor speed that's also shown in the video.

[@bigcheesevirus]

I hope this helps I ordered a full belt kit 4 weeks ago for my trk 8190e from stores.ebay.de/phonohifishop if the shops not showing any email them at [e-mail] or through eBay the cost with shipping to the UK was around 10 pound

[@80s_Boombox_Collector]

LOL, mine acts kinda like yours. Except it takes 30 minutes or more for the radio to fade in power. When it happens, I can see that the LED meter output has dropped to maybe half. If I jiggle the function switch, it goes back to normal power/volume. I tried spraying the function switch bar inside, but that didn't solve the issue. Strange.

Please sir, two questions. What is the piece of equipment you move in and out slowly? demagnetising the head?? Also, what is the mobile phone app for with the A,B,C and D? Thank you.

[@teddyhashee]

Head demagnetizer amzn.to/2DqYUdP App is called Tuner T1

[@flyone8350]

Could you do one of the TRK 7700H ? I'm just looking to disconnect power from the tape player so it's not running all the time. I have to unplug this thing to shut it off. Not so easy with taking out the batteries to shut it off. Something stays running in the tape player and it don't work anyway.

[@teddyhashee]

Probably main switch is not good. The model you have has logic button that means the motor always spinning when you turn the main power up even you do not use the cassette deck.

[@user-nv2fq7pb7o]

Good afternoon! I asked about the dimensions of the drive belts, the translator was mistaken.

[@teddyhashee]

This Hitachi, right now not in my possession, therefore I can not tell you the size of the belt. However, you can easily find out the size by replacing belts with many sizes. I always do with this way. Teddy

[@catleaderk]

この機種がとても気になっております。ちなみに、なぜカセットテープを再生した時に、左チャネルはあまり響かなかったのでしょか？磁気ヘッドはまだ汚かったのでしょうか？

[@teddyhashee]

この機種は基本的にcapacitorを交換しなければならない状況でした。私はそこまで時間が無かったのでそのままにしていますが、いつか根本的にアンプ部、プリアンプ部、および電源部のcapacitorを全て交換する必要があるでしょう。左チャンネルが弱いのは、左側のアンプ、あるいはプリアンプのcapacitorが古くなっているからです。

[@catleaderk]

なるほど。コンデンサの問題ですね。ビックカメラや他の電気屋さんのオーディオ専門家に聞いたことがありますが、コンデンサはバッテリーと同じ、何回充電すると、寿命になります。しかし、あくまでもコストの問題だと個人的に思っております。例えば、今私の手元に持っているYAMAHA NS-1000Mは、３０年以上のものですが、ヤマハさんのサービスセンターに送って、専門の技術者にプロ審査をさせても全く問題ないと判明して頂きました。実際な音を、私がアプロードしたNS-1000M映像をご覧ください。 ちなみに、Teddy Hasheeさんのコンデンサを交換する映像をとても見たいです。いろいろ勉強したいです。@@teddyhashee

[@catleaderk]

追記：メール連投大変失礼致します。もう一つを言いたい。もし本当におっしゃった通り、「左チャンネルが弱いのは、左側のアンプ、あるいはプリアンプのcapacitorが古くなっているからです」というならば、なぜラジオの時に問題はなかったのでしょうか？@@teddyhashee

[@teddyhashee]

この短いビデオの映像のみでは正確には検証できませんが、ロジカルにラジカセの音の問題を解決していくときにまず考えるのは、ラジオの音がステレオとしてまったく問題ない場合、しかしカッセットの音のみが片方音量が落ちるとき、たぶんプリアンプに問題があるのだろうと推測し調べていくことになると思います。この日立のラジオは片方の音量が低い理由が当初ボリュームおよびバランスのスイッチの汚れの問題と思いましたが、しかしそれだけでは完全には戻りませんでした。よって次はcapacitor、その他の電子部品の交換が必須となると思いますが、その先までは私は作業をこの時にはしていません。よってKAIさんの疑問に正確には答えられません。

[@karloflochalsh8817]
