Unless it's a Nakamichi, Sony ES or another well-sought-after high end deck, maybe a Pioneer CT-F1250 or CT-A9 or some older Duals, getting replacement gears is not worth the effort. Especially not for a rather questionable dual well Technics, probably with already-worn Ferrite heads that can't even reach 15 kHz 🤷🏼♂️ Technics had some killer decks back in the day, but this isn't one of them.
@@Remembergoodolddays Many decks had those mechanisms, many autoreverse decks from Technics and Panasonic (more or less the same company) and I think that also Denon used it.
Agree that this deck is probably not worth the effort, I've seen these gears on line as single units and larger quantities. My buddy who has just emigrated to oz is a Horologist and regularly files teeth in brass discs to make replacement cogs, using the old cog as a template. I used his equipment, desktop lathe, to ensure the 3D printed disc was round and the hole was centered. TUsinghen, using the old cog as a template I filed the teeth with a small triangular file that matched the pitch on the original cog. It certainly did a good job on my 30 year old JVC twin deck
I would have guessed the tape transport was from Philips as they were using such soft plastic basically everywhere, but it makes sense it comes from Alps. I can confirm the noise increases when the gear is replaced with a harder plastic type: I have a Philips CD 204 with a new gear in the drawer open/close mechanism and a portable CD player Philips D6800 with a new gear in the pick-up sledge movement. In both cases they work fine, but they are much noisier, the portable CD player especially is very noisy when changing track. But both gears are not critical for audio quality and I can live with the extra noise. (also both gears were already available, I just ordered them, no need to 3D design and print gears !)
I have been ordering from a guy on ebay out of Hungry for these gears. Done 3 decks already. They are louder but run like champs...push through the tapes reels quickly and don't bog down.
I have found there are replacement gears available, however, two of these gears cost more than a cassette deck like this is worth around here. So such a repair would be uneconomical.

I remember a little over 20 years ago noticing how many VHS VCRs were eating tape and it was almost always caused by the reel drive rubber tire glazing over or drying out. I was glad that the Panasonic VCRs we had at home used one of those soft (urethane?) rubber gears that never caused that problem and would seemingly last a *really* long time. Here we are a '*really* long time' later...and the rubber tires are looking a little better now since they're generic and more easily substituted. Not going to argue since you have more (and more interesting) decks come through your shop that might be a better use of the parts from this broken one.
Ugh I hated those awful tyres - high failure part found in a few 80s-era boomboxes as well; a royal pain to source and replace with new. The take-up spindle won't rotate if the tyre breaks, fails, or disintegrates, thus eating tapes.
I bought a replacement resin printed gear for my technics RS-B55 as it had the flexible gear with 3 teeth missing. The clonking has gone, but there is a low mechanical noise on playback, since I just enjoy playing cassettes and not a hi-fi buff it's not a big problem, but I agree with what you say in your video.
We have a resin printer at work that can print such details and we can print with rubber resin. It's a Formlabs Form 1, but due to current situation I'm in home office and not in the lab.
OMG, I had almost identical model before and had exactly the same issues, forward and rewind fine on right side but no play, on the left side, I only can play or record in the reversed direction. Thanks for revealing the reasons as I dare not to fix them.
That gear is easy to obtain for $11 shipped. It's out of Russia, and also another guy in netherlands. I've bought about 16 or so already to fix many Rs-Tr series decks. Just search eBay for the Technics part number ..you will get it. Also there is a video on how to fix that. There is no need to take anything off the back of the transport contrary to popular instruction. I've successfully repaired over 10 Rs-Tr decks already. You are right..you can't and should not 3d print that. With gears you have to respect module and pitch! You have no 3d printer that can respect that resolution....yet Sorry but I disagree completely on the soft plastic. I can and did replace several and hear no noise or problem. I only can't speak to longevity.
So I would need to buy two of these gears at a total cost of about 22€. The problem is, a cassette deck like this around here is worth maybe 10€ on a good day. So such a repair would not be economical. Of course, if there is sentimental value involved, this can be very different, but I personally don't want to loose money on my repair projects.
@@DrCassette That's a shame - I get about $100/usb ea serviced and repaired on Ebay - not much profit but enought to make it worthwhile. My bigger problem with these decks and I'm sure you may run across it: Sometimes the takeup hubs will seem to "catch" as they spin and drag. This happens because if you prise off the hubs on the front side, there is a little plastic collar against the back metal plate that centers the spring and that same spring rides on it. This hub will split, cause drag, and the spring will catch on the even minute split. I'm currently trying just some small flat plastic washers, but have only had limited success... Some of the newer decks i.e. with the motorized eject and rounded front are even more expensive to fix - the pinch rollers go bad and they are very specific 13.5mm with a strange collar. I cant find them for less thatn $10 shipped * 4 =$40...Now it's starting to get hard to make it worthwhile with those. (example RS-TR170) If you know a solution to either problem, I'd appreciate it. I just hate to see these discarded.
@@jimb032 I actually have not come across this problem with the takeup hubs yet. I have had hubs that had seized because of bad grease. Cracked plastic parts are always annoying. Indeed replacement pinch rollers are extremely expensive, I unfortunately have not yet found a better, low cost source for them either...
You don't want to "put up with ridiculous suggestions that are guaranteed to fail". You don't sound angry at all! You clearly have more knowledge and experience than I do, but check this out - My Technics deck didn't work. I bought a printed gear on ebay. Now the deck works. It's amazing.
I have since found there are replacement gears available, however, two of these gears cost more than a cassette deck like this is worth around here. So such a repair would unfortunately be uneconomical.
Hi, sorry but could you please send me the link of the replacement gears of the cassette player of this video in the reply? I have this same model with the same broken gears, but I can't find the replacement. Thank you very much
Measuring the exact dimensions of the gear is already hard enough, even if you could replicate it, it would never be 100% accurate unless you have the original cad drawings for it. The original moulds where probably made of steel and with very fine tolerances. I’m always amazed by how mechanical engineers can work with such small, precise dimensions.
Tested method by myself! Baking soda and super glue + file = you can construct missing teeth. The hard plastic is not a problem and it is better than missing plastic ;)
Not sure if it would work, but could you grind the teeth off the gears and use an O-Ring or tire in place? On the hub gears, can they be made to use a tire as well? Maybe worth a try just to see what happens for curiosity sake.
There is a fix that I have successfully applied, but bear in mind the mechanism.will be noisy and a bit messier. Proceed with putting a very small amount of HOT GLUE where the missing teeth are and they will turn fine. :-)
Don't let anyone make you nervous. I have a lot of stuff that isn't repairable anymore or where the pieces cost a fortune. Like you mentioned: is not worth it.
I've had similar problems with a Philips D8614 Boombox, but in my case the gears just rotted inside the machine and instantly broke into pieces. I asked a friend if he could 3D print me the gears, but for now he only managed to print me just one as he is having some issues with his printer. At least that one gear works just fine. Also, from what I know, these gears are made out of TPU.
I fixed one of such gears but the plastic was harder - I used JB Weld Epoxy to rebuild the broken gear and filled the material to required shape - time consuming process. As whether such soft plastic is really required - maybe Matsushita, sorry Alps, made it too soft compromising the longevity. Actually I would like to see the Uher deck mechanism to compare design and kind of materials used in it - hopefully less plastic.
I'm done with some Technics electronics now. Had an SU-V550 amplifier develop a fault after being repaired and then used for 5 hours and 45 minutes. Hopefully my partially repaired RS-615US cassette deck actually lasts after it's been fully repaired.
I have had mixed experiences with Technics equipment. Some of it is quite reliable and reasonably easy to repair when it fails, but other equipment is just terrible...
hi bob here you can save me a small bit time the trans in 12.5 0 12.5ac do you know the amps on each 12v power rails i now volts came from the amp it paired with when sold bob

Some people might want to go through the trouble of repairing a Technics deck but it is not really worth it unless the deck had sentimental value OR they just enjoyed the challenge. They are very nice but just not high quality. If it were a higher end JVC or Nakamichi (especially the Dragon) then yeah, it would be worth some money and effort. Good to know I wasn't the only one who had to dead with broken gears.
I have the same cassette player with the same broken gears. it's hell to find them! Can you recommend me some solutions please? I am Italian so if for example there is some site to redo these gears in which I can also access. Thank you very much
Apparently there are replacement gears available on Ebay (see the other comments on this video), but I have not repaired this cassette deck as it would have been uneconomical.

I don't know if it is worth the effort but this type of broken gear can be remade with resin. I have already made this with several decks and turntables
These cassette decks need gears in the mechanism replaced, as shown in this video. There are plenty of other cassette decks of equal or better quality, that don't require such repairs.

@@DrCassette Auch schon wieder 6 Monate her ;-) Sowas, sowas. Tatsächlich hat aber das Autoreverse Laufwerk meines Technics viele Plastikzahnräder, darunter auch welche aus vermeintlichem Softplastik. Auch das Direktgetriebene RS-BX 606 hat Zahnräder, die ganz danach aussehen, bei diesem Laufwerk sind aber hauptsächl. andere Bauteile aus Plastik von Verschleiß betroffen (Assy-Gear)
@@DaXande135 Das ist gut zu wissen, dass auch die Technics Cassettendecks mit Quarz Direct Drive Probleme mit Zahnrädern haben. Ich hatte mal überlegt, mir eines dieser Modelle zu kaufen, denn mein Akai GX-75 hat zwar Direktantrieb, allerdings ohne Quarzreferenz, sodass die Bandgeschwindigkeit immernoch danebenliegen, oder mit der Zeit sogar driften kann.
@@DrCassette Für die Zahnräder gibt's Ersatz zu kaufen, das ist kein Problem. Vielmehr habe ich mit diesen Decks Bandknittern bei bestimmten Kassetten ab 90 Minuten Spiellänge. Betrifft vorallem BASF Chromdioxid-Kassetten und maxell UR der letzten Generation. Habe nun schon ein zweites solches Deck hier gehabt und egal, ob mit originaler oder neuer Andruckrolle, sogar mit neuem NOS-Andruckrollenarm von Panasonic, tritt das Problem weiterhin auf. Die Zugkraft der Wickeldorne kann man hier leider nicht so einfach einstellen... In einem Forum hat desweiteren jemand gesagt, bei ihm trat das Problem schon in den 90ern auf, als der Tonkopf bereits einen leichten Einlauf hatte. Zu dem betroffenen Zahnrad: Dort gibt es ein sog. Assy-Gear, das mit einem Art Arm am Wickelmotor befestigt ist, dieser Arm kann durch Brechen des Plastiks an der Motorwelle verrutschen, sodass die Zahndäder nicht mehr ineinandergreifen. Ansonsten sind gerade die höheren Decks von Technics immer ganz schön gewesen, gerade auch wegen dem Quarz
Even some Nakamichi decks employ plastic gears - only to fail a decade or two later. This is poor design/engineering. The Sony decks I have employ a drive shaft on to a rubber tyre - effectively a friction drive with acting slippage, these are theoretically repairable. Pity about the Technics DC, and rather annoying too!

*Some more info and thoughts:*
- It has been pointed out that there are replacement gears available that have been made from a mould of an intact original gear, as discussed in the video. However, two of these gears cost more than a cassette deck like this is worth around here. So such a repair would be uneconomical.
- While I am taking part in this debate, I am not looking for ways to reproduce gears myself. I don't consider many cassette decks worth the effort of reproducing gears.
- These broken gears each have 42 teeth. The teeth have a special shape, they are not just triangles arranged around a circle.
- Apparently some high end filament based 3D printers are able to achieve a print resolution of 0.1 mm, which would be good enough.
- The prints from resin based 3D printers are apparently not long term stable. UV light is used to harden the printed resin, but any further UV exposure (admittedly unlikely inside a cassette deck) further hardens the resin, so eventually the material becomes brittle.
It will be great if someone can give a link to buy gears like this. I have Philips but the teeth direction are under a corner, so more difficult. 🤔
You have the same kind of cassette deck and same plastic wheel on many Technics as well as Panasonic Rx-Dt and sisters. Hope it helps, Best, Ingeltech
Unless it's a Nakamichi, Sony ES or another well-sought-after high end deck, maybe a Pioneer CT-F1250 or CT-A9 or some older Duals, getting replacement gears is not worth the effort.

I used his equipment, desktop lathe, to ensure the 3D printed disc was round and the hole was centered.
TUsinghen, using the old cog as a template I filed the teeth with a small triangular file that matched the pitch on the original cog.
It certainly did a good job on my 30 year old JVC twin deck
I would have guessed the tape transport was from Philips as they were using such soft plastic basically everywhere, but it makes sense it comes from Alps.
I can confirm the noise increases when the gear is replaced with a harder plastic type: I have a Philips CD 204 with a new gear in the drawer open/close mechanism and a portable CD player Philips D6800 with a new gear in the pick-up sledge movement.

But both gears are not critical for audio quality and I can live with the extra noise. (also both gears were already available, I just ordered them, no need to 3D design and print gears !)

I take your points about being of a soft material but I take what I can get and if there is a little whirring then I don't mind. At the moment I get this terrible ticking because of 1 broken tooth. I bought 2 so that I can replace it again in the future if needed.
Thanks for tip - I check what he has in inventory - I need gear for Sanyo based Nakamichi.
I have found there are replacement gears available, however, two of these gears cost more than a cassette deck like this is worth around here. So such a repair would be uneconomical.
hi this video is very out of date there is someone making gears for the deck the only thing is the cost of them i have 3 decks and i only had one gear bad out of 6 gear
they do break up they go soft and start to fall in to small parts
i will say there is away to use this model of decks no need ti bin them ever i just done work on my tascam 238 deck it 100% working yes the DB ic go in them
still sounds ace i think the Technics RS-X is over priced on ebay because of the bad gears and price of new ones i workrf on alot of deck the micro stereo cassette decks are a right pain to fix
Those gears are avaialble on ebay i bought some that are 3d printed and they work pretty well
I have a panasonic R sereis boombox that used these gears would you like the link?

@@DrCassette thats to bad i found some for 12 usa dollars and it saved my boombox that was clicking I have an panasonic DF 55 or FD 55 i cant remmeber and wanted to save it its my favorite.
@@stpworld One of these replacement gears costs about 10€, I would need two, so the total cost would be about 20€. But a cassette deck like this is only worth about 10€ around here on a good day...
hi there is a way of fixing them i have done it i see if i have any gears left to make a video it very clever what i did
Broken gears suck..... I lost a Nice Phillips thingy to broken gears
Philips equipment often has problems with bad gears. They used a strange soft plastic that goes brittle over the years.
@@DrCassette nylon gears perhaps
@@lukedavis436 No, it's not nylon, it's a really strange material that after years takes the same consistency as cheese...
There are even more better 3D printers these days to make a new gear even as small and precise as this one
HI DR
i have alot of this model i have not seen one yet with bad gears they are very small it's luck what you get i think the amp goe's first please don't run this model down
in all make's there's bad part like the old lego brown bricks that can break i have 1000's of the old brown lego plate's brick an not came in to any bad one's
it's like the this deck and the one's i have i have had cassette decks need alot of work big time
I prefer DENON Cassette Deck DN Professional series only.
Und ich habe genau ein solches Doppel tapedeck von Technics, nur neuer, BJ. 92-94 denke ich. Wird also der selbe Mech. sein. Schade
Eine neuere Serie kann schon einen Unterschied machen, da würde ich keine voreiligen Schlüsse ziehen.
@@DrCassette Auch schon wieder 6 Monate her ;-) Sowas, sowas.
Tatsächlich hat aber das Autoreverse Laufwerk meines Technics viele Plastikzahnräder, darunter auch welche aus vermeintlichem Softplastik.
Auch das Direktgetriebene RS-BX 606 hat Zahnräder, die ganz danach aussehen, bei diesem Laufwerk sind aber hauptsächl. andere Bauteile aus Plastik von Verschleiß betroffen (Assy-Gear)
@@DaXande135 Das ist gut zu wissen, dass auch die Technics Cassettendecks mit Quarz Direct Drive Probleme mit Zahnrädern haben. Ich hatte mal überlegt, mir eines dieser Modelle zu kaufen, denn mein Akai GX-75 hat zwar Direktantrieb, allerdings ohne Quarzreferenz, sodass die Bandgeschwindigkeit immernoch danebenliegen, oder mit der Zeit sogar driften kann.
@@DrCassette Für die Zahnräder gibt's Ersatz zu kaufen, das ist kein Problem. Vielmehr habe ich mit diesen Decks Bandknittern bei bestimmten Kassetten ab 90 Minuten Spiellänge.
Betrifft vorallem BASF Chromdioxid-Kassetten und maxell UR der letzten Generation.
Habe nun schon ein zweites solches Deck hier gehabt und egal, ob mit originaler oder neuer Andruckrolle, sogar mit neuem NOS-Andruckrollenarm von Panasonic, tritt das Problem weiterhin auf.
Die Zugkraft der Wickeldorne kann man hier leider nicht so einfach einstellen...
In einem Forum hat desweiteren jemand gesagt, bei ihm trat das Problem schon in den 90ern auf, als der Tonkopf bereits einen leichten Einlauf hatte.
Zu dem betroffenen Zahnrad: Dort gibt es ein sog. Assy-Gear, das mit einem Art Arm am Wickelmotor befestigt ist, dieser Arm kann durch Brechen des Plastiks an der Motorwelle verrutschen, sodass die Zahndäder nicht mehr ineinandergreifen.
Ansonsten sind gerade die höheren Decks von Technics immer ganz schön gewesen, gerade auch wegen dem Quarz
there is soft resin out there you got to get the info out of people it is not that easy i can tell you
I have a spare new gear if you want it.
Thanks for your offer, but this cassette deck is now gone...
Even some Nakamichi decks employ plastic gears - only to fail a decade or two later. This is poor design/engineering.
The Sony decks I have employ a drive shaft on to a rubber tyre - effectively a friction drive with acting slippage, these are theoretically repairable.
Pity about the Technics DC, and rather annoying too!
A Nakamicchi would be worth repairing though. Technics - not so much.
@@Lesrevesdhiver Agreed, but finding suitable gears may be a big problem.
Technics although a great brand of audio components their cassette decks are not so good. I only buy their Turntables
