    Nice work as usual! I found with the more aggressive contact cleaners, they sometimes dissolve parts of the plastic from the spray caps, that might be why the liquid looked a bit red. Had the same effect with another brand of contact cleaner after I had it sitting unused for a while. Didn't seem to affect the contact cleaner in any way apart from the slight discoloration though. Interesting that the lighter fluid did such a good job. I might try that in the future. I am always very hesitant about using any chemicals at all on the pinch rollers.

    DrCassette, may I kindly suggest you use potentiometer cleaner. Or maybe not all are the same...I am using, altough not often as you, of course, MA potentiometer cleaner. I have "repaired" some scratchy pots and a recording switch as well. The main difference from a contact cleaner is that it leaves a somewhat oily residue which not only lubricates the switch but it also acts as a protective pelicule and keeps the oxide forming. To be honest I have not used another type of potentiometer cleaner as I have this bottle for 2 years and is half empty. But the reason I have tried it is that the contact cleaner made had the same issue when spraying an old Sharp personal cassette player volume pot. i am sorry that I cannot insert the image here. It was also very cheap, 4 Euro's in Romania

    Interesting method to restore the record/play switch. However, as these switches are not available anymore, in many cases it is needed to remove the switch and dismantle it to check how good the contacts are and clean them manualy one by one. The TC450 is worth being repaired. This models from Telefunken were among the first ones to be capable of recording tapes with high frequencies reaching up to 18khs and above, a truly remarkable achievement for that time.

    • @DrCassette
      @DrCassette  3 ปีที่แล้ว

      A Telefunken TC 450 over here is worth maybe 30€. That is not what I consider worth the effort of completely removing and disassembling the record/play switches. Sorry.

    • @senilyDeluxe
      @senilyDeluxe 3 ปีที่แล้ว

      I've been using the same method for decades. It's unreliable, but it'll work eventually. Good if you need the machine to be working now. Like if it's the bottom machine in a tower or something.
      If it goes on my nerves enough or someone wants it, then I dismantle the switch and clean the contacts one by one. By now I take about an hour for the complete process (plus an hour to disassemble the machine to get to the switch and reassemble it back afterwards)

    • @profibere
      @profibere 3 ปีที่แล้ว

      Yes, your are completely right if we take into account only the price of the equipment now. I was talking about the personal value of preserving the memory and history of the cassette decks. The majority of the models of the same era are not worth the effort to preserve them, in my opinion, because they were too bad even in those times. It´s not the case of this Telefunken, that was among the first ones to reach high frequencies as high as 18 to 20 kHz, a tremendous achievement in the 70s.

  • @BijanKafi

    Be careful with Kontakt WL. Contrary to what one might expect, it’s not a “neutral” liquid. It aggressively corrodes plastics, particularly those types that where surface-treated and widely used in the early 90s as cases for Walkmans or other stereo equipment.

    • @DrCassette
      @DrCassette  3 ปีที่แล้ว +3

      In various online forums I read that Kontakt 60 can be washed out either with IPA or WL. I have found that in most applications I used to use WL for, IPA works just as well, while being cheaper and causing less of a mess. So one reason I chose to use WL was actually because it seemed like a way to finally use up the can of WL that has been sitting around for ages and that has lost all of its pressure. What a bad idea that was. It took ages to clean out the WL with IPA afterwards...

    • @BijanKafi
      @BijanKafi 3 ปีที่แล้ว

    I have seen a trick where someone used the car tire nipple, pulled off the cap from the can with no pressure and placed the tire nipple over it and put pressure back into the can with the compressor!
    I haven't tried it myself but I have remembered it just in case I ever run into the same problem again for which I have in the past but didn't know about this particular trick...
    Great job on the cassette deck! I still have yet to come across a HiCom machine in Australia! I would love to know how it sounds compared to Dolby or JVC's noise reduction...

  • @19janiboy96
    @19janiboy96 3 ปีที่แล้ว +2

    The most reliable technique to clean switches is to use Kontakt WL or Tuner 600 to flush the particular control then blowing it dry with compressed air. Afterwards you use 1-3x squirts Teslanol T6 Oszillin, then just a little compressed air. Finally some Deoxit D100 or White grease Spray to seal and just a tad compressed air. Also don't forget working the control back and forth at least 10 to 20 times. If come to this conclusing after 6 years of Repairing audio gear and working at a professional repair shop for some time.
    Although if you have the time and patience disassembling and cleaning manually is always the best option.

      Ajax Soap works well to clean rubber parts in tape decks.
      Seized mechanical parts can be made movable by heating them with a hair dryer, then some Kontakt WL. Afterwards some mechanical oil.

    Hallole! Das Kontakt60 benutze ich seit 30Jahren nicht mehr! Das ist der Poti- und Kontaktekiller schlechthin! Auch nach dem spülen hat das munter weiter gefressen. Leider wird das auch heute noch häufig benutzt. Die Freude ist groß wenn nach der Anwendung alles wieder funktioniert; die Enttäuschung groß wenn nach einigen Monaten der Totalausfall kommt. Reinigen mit Alkohol, wenns dann nicht funktioniert die Kontaktleiste demontieren und zerlegen, Ultraschallreinigen, spülen mit Wasser anschließend mit Kontaktfett wieder zusammen bauen. Bei hartnäckiger Korrosion vor dem Ultraschallbad mit Messingpinsel oder Glasfaserstift reinigen.
    P.S: Das TC450 hab ich auch! 🙂

    • @DrCassette
      @DrCassette  3 หลายเดือนก่อน

      Kontakt 60 nutze ich nur, wenn Tuner 600 keine guten/dauerhaften Ergebnisse liefert, und natürlich nur in Schaltern, in Potis hat das nichts verloren, das ist mir wohl klar. Die lassen sich ja auch noch halbwegs gut zerlegen für eine gründlichere Reinigung. Bei komplexen Schaltern kommt das für mich nicht in Frage. Es ist ein irrsinniger Zeitaufwand, und wenn man Pech hat hält solch eine aufwändige Reinigung kaum ein Jahr, dann geht es von vorne los.

    • @Black-ForestEnchantress
      @Black-ForestEnchantress 3 หลายเดือนก่อน

      @@DrCassette Das Problem ist halt folgendes: Im zusammengebauten Zustand sprüht man in der Regel immer durch Ritzen oder kleine Löcher/Öffnungen. Da kann man spülen wie man will, man bekommt nie alles raus! Deswegen zerlege ich Schalter und Potis wenn man mit Ethanol oder Propanol nichts erreicht; im zerlegten Zustand kommt man überall hin! 🙂 Je nach Material kann man auch das aggressivere Aceton oder Butanol verwenden; allerdings vertragen das einige Kunsstoffe nicht.

    One thing about cleaning the heads with IPA.
    I've got one case where erase head after cleaning it with the IPA got melted when the IPA started to vaporize. Finally the head surface got pretty much rought and it was needed to be replaced to avoid damaging the tapes.
    I've Had this in Grundig radiorecorder unit, probably RR 450 model iirc. I don't know from what material it was made, but the color of it was dark brown and it didn't like the IPA at all :).

      For some time Philips made erase heads that cause lots of problems. In some cases I have had, the surface had turned rough as you described, in one case part of the head had melted, so there was a sticky mess and metal components of the head were sticking out at the front. I would assume Grundig used one of these strange Philips erase heads.

    If I’d only had waited a week with working on my technics RS-M205 deck. It had a weird issue with the recording (the VU meters would hardly move whilst recording) and it produced a high pitch sawtooth tone when recording. It seems it had a dirty record/play switch as well. I cleaned it with Kontakt 60 and now it’s good. However, I forgot to rinse with IPA afterwards. The can itself is corroding quite a bit at the bottom, the can is about 5 years old now. With this deck, I record my own compositions to chrome trapes as well as backups of C64 games. Maybe it would be a good idea to spritz the contacts with IPA now since the Kontakt 60 is so corrosive……

      Another M205-owner here ;-). Tip: for backing up computer games: I heard it is better not to use a HiFi-Stereo deck for data, I can imagine that the 2 channels might interfere with each other and create a less quality (for the computer) signal. At least, with my MSX, I always had bad experiences with stereo decks for loading games...
      @DrCassette: Thanks for the tip with the IPA, I knew that Kontakt 60 is very powerful, but can also be very destructive. I always try to clean it off with a tissue, but in closed potentiometers and switches, that's of course not possible...

      The tape will have a tendency to mistrack. It will wander off to the sides, which will cause strange effects in the sound. In really bad cases the tape will be pulled through at an angle, causing severe damage to the tape. If a cassette tape gets wrinkled on playback, that is usually due to a bad pinch roller.

    I got this tape deck for a good price. I inserted a cassette and played it. The sound was very "rough". After about 20 minutes it suddenly stopped playing. The play button remained engaged (so it wasn't the final cut-off). You then have to switch it off for a long time and press STOP to disengage the play button. The belt for the capstan shaft is still in order. After about 15 minutes, playback starts again, but only for a few minutes. Then it stopped again. What could be the reason??????

      Hello, it's true, but Telefunken was fully based on Hitachi only after 1979. This model has Japanese components but it is still partly German design and production. This can be seen from printed circuit boards and some integrated circuits. Those marked with U or TFK are the production of Telefunken. Hitachi chips are labeled HA and HD. Electronics and so modules are, as I wrote above, a European project and German design with subassemblies partly European and partly Japanese. The mechanism with the Sankyo engine is already a Japanese job. But that's not full of Hitachi yet. It's partly Telefunken.
