Thank you :)

Thank you :)

Yes, it's one fault after the other - I could have kept this video going probably for another hour, but eventually I decided the condition it's in now is good enough for me :)

I actually used to use some real dental floss that I had left over for things like this, but I ran out of that dental floss years ago...

Was ist denn der Unterschied High Com oder nicht? Habe selbe ein Telefunken RC100

@@kl6990Nun, HighCom gibt Dir einen um einiges besseren Rauschabstand. Meiner Meinung nach klingt die Musik mit HighCom besser als mit Dolby B und C....analoger, aber auch brillianter. Selbst bei einem Frequenzgang bis max. 15khz ( Telefunken RC 100 ) sollte das evident sein.

Vielen Dank erstmal für die nette Erklärung. In den 80er war ich froh überhaupt ein Gerät zu haben, welches Kassetten abspielt.Erst heute hinterfrage ich solche technischen Details. Ich kann aber beim Umschalten auf Com keinen grossen Unterschied feststellen bzw eigentlich gar keinen.Vielleicht liegt es aber auch an den Lautsprechern.

Ich habe das heute für 35€ erwischt, braucht nur neue Riemen. Zustand ist auch noch ziemlich gut

@@felixlutticken5694 Sehr schön! Herzlichen Glückwunsch. Derzeit habe ich auch die Auswahl an günstigen Ersatzdecks Telefunken RC 200 in Frankfurt / Offenbach( ab 35 -55 €), falls ich mich dazu entschließen sollte. Wenn ich nicht schon 6 tape decks hätte:).

Thank you! :) Sanding the surface of rubber idler wheels and pinch rollers is not that difficult. For sandpaper, use the finest you can find, the finer, the better (highest number). The fine sandpaper will not take off much material at a time, so the risk of creating a flat spot by taking off too much rubber is very low. Ideally the wheel or roller is rotating while sanding.

You should change the orange capacitor in the old electronic board (6,8nf) and will work

Yes ! Telefunken RC 200 and Blaupunkt XC 240 are most most similar, because Both Tape Decks are made by Funai Japan ! You can identificate Devices are from Funai : The Order Number of Printed Circuit Board are 7 Digits, beginning with 161....

Viel Erfolg bei der Reparatur! Dieses Video sollte da hoffentlich ein paar gute Hinweise geben.

I have previously turned idler tyres inside out, but in this case the tyres are too small for that to really work.

Very interesting, thanks for the info!

The replacement motor that was in this cassette deck I put in 8 years ago. It was lubricated back then to fix the same noise that the motor had re-developed in this video. So adding oil was not a permanent fix which leads me to believe there is something else wrong with the motor.

Thank you :)

HighCom is one of the best consumer noise reduction systems. It's based on the professional Telcom C4 that Telefunken developed for studios and broadcast applications. HighCom is far better than Dolby B and C, better than dbx thanks to better circuitry and certainly about as good as Dolby S. Nakamichi later on developed the HighCom II system that was based on HighCom. Unfortunately HighCom was more expensive to license and produce than Dolby, so the Japanese industry was not interested. So HighCom faded away together with the German consumer electronics industry in the mid 80s.

@@DrCassette That's fascinating, DBX never really worked for me although I have seen Techmoan do a demonstration of it with an encoded record and I was blown away! All that I ever got was a very unstable level where loud parts were too loud and soft parts couldn't be heard! Either I was using the wrong cassettes to record with or I just didn't know what I was doing LoL.. So basically it's always been Dolby C for me. I have noticed that not all Dolby Noise reduction chips are the same, some Dolby C chips perform better than others, I remember finding a list on line of all the different Dolby chips used by manufacturers of cassette decks. I think that one of these days I'm going to get my hands on some HighCom chips to experiment with, there's also a noise reduction chip that was made by National Semiconductor which didn't have a licensing fee. So if you come across a cassette deck which just has NR but no Dolby, it would be a national... If you daisy chain then, they work better, two Dolby B in series gets you one Dolby C... Same thing for the National...

As I explained in the video, all tyres are now the original sizes again.

How long does the boiling method last? It can't be a permanent solution? I still have the original belt, so I could give that a try, but not if it only lasts for a month. I do have the equipment to get a direct recording, but I don't need all of KZfaq's self declared experts on everything to then use that direct recording to point out everything that's not perfect with the cassette deck.

@@DrCassette My very fuzzy excuse for a memory says that not only do the boiled belts hold up pretty well, the procedure can even be repeated if needed. I think @12voltvids has resorted to this on occasion (even using a microwave) when there was no matching size in the stash. For obvious reasons, 1. the belt needs to be the right material for this to work (synthetic rubber) 2. you want to be using a *spare* pot, cup, glass or whatever that no longer gets used for food items.

Thanks for the info!

That is the old Matsushita logo. Matsushita is the parent company of National, Panasonic, Technics and they controlled JVC until a few years ago. Recently they renamed themselves to their best known brand Panasonic, and took over Sanyo.

It certainly is possible, I have had this happen on various of these early full logic models...

Yes, the motor came out of that RC 100.

There will be more of these videos, hopefully soon.

This cassette deck is equipped with the excellent German HighCom noise reduction system. Better than Dolby B and C and dbx, but unfortunately not successful on the market. For playback of prerecorded cassettes with Dolby B NR, there is a Dolby expander.

I am not sure if Telefunken was active on the US market at that time...

The heatshrink tubing I have both in unshrunken and shrunken condition has a very smooth surface, not at all like rubber. So I don't think it would work very well, the idler tyres would not get a very good grip on that. But I have thought about this solution before.

I restored the original idler tyres by sanding their surfaces with a very fine sand paper. If the pivot mechanism that the idler wheels are mounted to doesn't move, check for dried up grease.

Telefunken is a German brand, this cassette deck however was already made in Japan, by Sanyo as far as I know. The Siemens RC 333, despite looking totally different, uses exactly the same mechanism and has a very similar power supply section - the metal shield I put onto the transformer in this video in fact came out of a Siemens RC 333 I took apart many years ago (before I knew how to repair cassette decks). Telefunken's top of the line model of 1981, the RC 300, was still made in Germany. Inside it looks totally different from the RC 200.

There are lots of very different mechanical designs. Maybe you can find some info in the service manual for your cassette deck.

There are electrical contacts behind the shiny silver pieces on either side of the cassette compartment. They serve the same function as the stop button.

Make sure the counter belts are okay. If the counter stops, it will trigger the auto stop after a few seconds.

@@DrCassette Cool! I will check that. Thank you! :)

Der im Glasreiniger enthaltene Alkohol ist geringer konzentriert als im puren Isopropyl-Alkohol, die Gummiteile sollten davon also weniger stark angegriffen werden. Meistens bringt der Glasreiniger auch schon sehr gute Ergebnisse. Wenn die Reinigungswirkung nicht ausreicht, nehme ich Isopropyl.

@@DrCassette Cool. Danke Dir.

Not sure what exactly you mean by silent mechanism. Is it a fancy one with 3 motors? In that case it's a variant of the full logic mechanism. Try to find the service manual for your cassette deck, it will contain further info.

For my repairs I use fine oil (sewing machine oil) and white lithium grease.

If I scrap a cassette deck I always keep the heads so I can re-use them in other cassette decks. I have no idea where you could get new heads today.

@@DrCassette Thanks Dr C, if I manage to find a supplier of new heads I will let you know

Designed in Germany, but made in Japan, by Sanyo as far as I can tell.

To connect the cassette deck to the scope all you need is a little RCA to BNC adapter.

HighCom ist eines der besten Consumer-Rauschunterdrückungssysteme. Basiert auf dem professionellen Rauschunterdrückungssystem Telcom C4, das Telefunken für Studios und Rundfunkanstalten entwickelt hatte. HighCom ist weit besser als Dolby B und Dolby C, besser als dbx dank besserer Kompander-Schaltungen, sicher ebenbürtig mit Dolby S. Nakamichi hat später basierend auf HighCom ihr System HighCom II entwickelt.

@@DrCassette schön das du hicom nach all den jahrzehnten noch so preist! technisch stimmt das ja auch alles, nur leider hatte man in der praxis wenig davon, wenn man mehrere tapedecks/autoradios/boombox bedienen wollte.

@@revolutronic Ach, nun sei doch nicht so negativ! Cassettendecks mit HighCom gab es in den frühen 80ern zumindest auf dem deutschen Markt reichlich, ein transportables System mit HighCom hatte Telefunken meines Wissens auch im Programm. Und Autoradios waren in den frühen 80ern noch nicht so weit, da gab es auch mit Dolby kaum Modelle.

I am here.

Thanks for your feedback. I told KZfaq to place ads at the start of the video and during the video, but it seems like they can't be trusted with where they place the ad during the video. I will have to place them manually to make sure the ads are at least 10 minutes apart. You really don't get much advertising on my channel, no sponsored videos, no videos of me advertising a product (turning the entire video into an advertisement). But I do want this channel to at least cover the costs it generates for me...

Well.. I have subscribed to KZfaq premium and didn’t see them 😁 - yes, I don’t like them, I assume part of the 15£ fee goes to your channel 🇬🇧

You mean the decorative metal flap that covers the mechanism? It is not supposed to open in any way, but it should move out of the way when you insert a cassette. If it does not, check that the heads are not stuck in the up position for some reason.

@@DrCassette Thanks for the reply, i fixed it. It seems i pressed play without having a cassette in, the two black arms popped up and didnt close back down, they kept the metal backside open. I opened the deck and manually moved the black arms. Now it works fine. Thanks for the replay but i should have deleted my message. :)
