Hello! Welcome to my page. This is a page showing the renovation and repair of old audio devices. I do renovations primarily as a hobby, I started making the videos mainly for my own entertainment, but I am happy to share them with others, in case it helps during a similar repair.
RETRO DECK
Пікірлер
Too bad the annoying and distracting background music started suddenly, nice video for the remainder.
My dad has this tape deck and the recordings sounded amazing...He passed it onto me in the late 90s. My bedsit was unfortunately broke into and it went along with a few other of my things and i never saw it again! 😔
how did you remove it?
Replaced all belts but rewind is very sluggish at best,i believe I'll try to locate a large tire for the rew.hub. Also the auto stop doesn't nor has it ever worked. Any idea on that would be appreciated at your leisure. Thanks Randy
Hi. You can see the drive in this video, you can only solve it by repairing the idlers and belts. However, the automatic shutdown can be due to many things. Check the plunger. This disconnects the mechanism. Check the voltages on the power supply board. The plunger works with 32 volts. On this panel you will find several diodes, check them as well. Here you will find a fuse resistor marked FR1. Replace this, it is most likely the fault.
@@retrodeck1956 Thank you kind sir for replying so quickly. My dumbass put the wrong rew/ff belt on as in putting the old one back on,I got them mixed up with a Pioneer ct-f1000's belt kit I'm working on that just happened to be too close. Anyway enough of my brain degenerative moments. I had no clue Fr1 was a fuse,so after I just read your post I checked it and got 90ohms darn the luck. The solenoid and plunger function well when temporarily as in split second shorting the ground terminal to the solenoid body or chassis gnd. D8 ,c13,c22 tr7 and 4 test good out of circuit. Thinking about looking at tr8 and tr6 tomorrow, as for now old butt is about to hit the bed after working on lawnmower then mowing and it is after midnight in my sleepy little town. Again thanks so much for taking the time to respond to your viewers! Kind Regards Randy Brown
@@RandyWBrown If the transistors are fine and the voltages are good, then only the solenoid switch can be checked. If I looked correctly, the signal is sw902. I hope the device was repaired. I have also been mowing the lawn for two days. But now it will be rest. Good luck to you. T Zoli
@@retrodeck1956 Hi Mr.Zoli and hope you're resting well on this fine Sunday afternoon. One quick question and I'll stop bothering you, I'm getting correct voltage everywhere on the ps board which as you mentioned earlier to check along with the reed switch. I get 34v on the collector of tr8 that goes directly to the reed switch when unit is not playing, just on. When play or ff/rew is pressed and counter is rotating, the voltage is all over the place from 0 to 32v and everywhere in between for milli seconds, shouldn't that be a stable voltage and if so I guess a new reed switch is in order. Thanks and enjoy the rest of your day. Kind Regards Randy
Thanks a lot for the video. Would you mind explain what lamps did you put to replace the old ones and where to find those lamps (LEDs? charactristics?) please? Many thanks.
@@yannicklepaleo Hi! Car dashboard light, if I remember correctly, I used a 24 volt one. Its performance should be as small as possible.
Hola , de donde sacaste el repuesto de la goma pequeña de la polea ? Gracias por tu respuesta
@@josemanuel-ux2xn Hello. Unfortunately, these parts are no longer available. That's why I make most of these idlers rubber wheels from high quality water fitting sealing rubber. It is very cheap and can be purchased at any hardware store.
I HAVE THIS ONE! Working good and sounds perfect
Akai GX-730D is one deck that is extremely difficult to repair compared with Pioneer and Sony made in the same years. But its well worth it for the sound. In good working condition it actually sounds like the GX-747 open reel deck
Смотрю на лентопротяг и не могу понять, а где автореверс?
I don't understand what you mean, but look at the head in this device.
@@retrodeck1956Возможно я ошибся и в этой деке не предусмотрено такое.
Основная фишка 220 - это ускоренная запись одновременно двух сторон кассеты, ну а послушать ее не переворачивая можно и в других деках, где автореверс предусмотрен.
@@user-ld3tc2mr3g Yes. It doesn't play back there. can only play normally. However, the heads are 2x2 channels. Thus, even when playing in one direction, it plays and records sides a and b simultaneously in accelerated mode.
Hi, I have an KD-A2. Powers on but no function wirh any button like play, ff, rw. Any suggestions. Maybe the motor is dead😂
@@chamni63 Hi, if you hear the sound of the engine during playback, take the top off the device. Check the condition of the belt.
@@retrodeck1956 ok, thanks
Can you tell me the specifications of led diods you use? Volts, ampers?
The type is smd 0603, they are sized for a all of 2.1 volts. It should have a low brightness, which is approx. 8-14 mcd. But you have to experiment with it, because the light of the red and green LED is different.
@@retrodeck1956 thank you 👍
On my deck right vu meter stop work couple years ago.....only left work....i change all leds and it s the same......definitly the IC on right chanel is dead😞
@@Predator2690 When I repaired this device, I thought that if there was an IC error, I would install a ready-to-use LED display unit. Obviously more work, but in my opinion it can be fixed this way. I bought the LED unit, approx. The price was 6 euros. But I didn't have to use it.
@@retrodeck1956 Thank you....i'll see what i can do ☺
I also have this machine, I've been working on it for a week now. One thing I have noticed - the RW torque as applied to the supply reel (leftmost) needs to be strong because the take-up reel (rightmost) is highly frictional. The main clutch at the rear must be able to generate high-slip friction. The small square belt I use is 37.5mm diamter x 1.5mm x 1.5mm; a slack belt won't be able to transfer the torque as applied by the motor pulley. Although, I think a 38mm ... 40mm diameter is okay, but *1.2mmx1.2mm* thickness is no good.
You're probably right. These machines are very difficult to adjust from this point of view. I experienced this while repairing a GXC 730.
If you can give a tip where to look please? My f11 in mint cosmetics, nicely play and ff/rew after tyre change. BUT it does not completely erase old records 😢 some 10% volume stays. Any professional advise where to look? Mechanics or electrics? PS looks like I assembled it correctly after tyre change, spring in place, front plate on mechanism goes up smooth. Thank you in advance.
Hello. There is probably an electrical problem. If the recording and playback quality is good, then the combo head is probably good. Check the wiper head. The resistance of the heads must be measured. If it is OK, then the oscillator signal feeding to the heads must be checked. You can check the signal with an oscilloscope. The signal is only in recording mode, then you can measure it and search for errors. Check the transistors TR14 TR15 TR16 marked in the service book connected to the oscillator and the specified voltages.
@@retrodeck1956 thank you!
WOW . Very Clever .
Bocsi. Kerestem, de nem tudom milyen típust nézzek, mert rengeteg van. Tudsz mutatni egy mintát, vagy egy típusszámot írni.
A szilikonbolt.hu oldalon találsz zsírt, általános célú használatra valót, kis kiszerelésben is lehet vásárolni.
Great video, thanks for the upload. We can see why many tens of hours go into repairing these old classics.
Thank you for your comment.
Thank you for your comment.

Valami jobb fajta szilikon zsírt, kis kiszerelésben is lehet kapni, én ezt szoktam használni.
Hello, I just changed the belts on my AKAI GX 65. Unfortunately, after switching it on, the counter flashes and it doesn't work. Heads don't go up. At least you could fast forward beforehand. Maybe you have some advice. The drive position is probably not correct.

Update Jun 4th, 2024, i own the TC-K1A/2A/4A/5 and 6 and . . . . the TC-229SD. Skip the TC-K7II. Make my own RM-30. Renew elco's, belts and pinchroller. Mechanisch for auto stop is from poor quality. Demagnetisize the audioheads. The blue finish on the VU meter lamps are removed so it gives a warm white light I love more.
Hello am looking forward to buy a Akai V's 2 eg 1983
Hermoso. Lo tengo y quiero dejarlo limpio en sus circuitos como este, estéticamente está sin rayas solo algo en la cubierta. 👍👍🇨🇱
Hi, I have just bought an Aiwa AD 6350 cassette deck, it needs new belts, can you do a video please on fitting new belts? When i press down on all the buttons the motor runs, good sign.
There is a video about the 6400, I think it has the same mechanism.

Cheers 😊👍
I just put one of them off the internet that looks like a complete nightmare to repair I'm pretty confident and repairing stuff but that's Be on my ability of there's a problem with it I have about 28 different tape decks a very in price all sort of mid to high end you can get a bit addictive 👍👍
We had this cassette deck!!!!! LOVED IT! Wow. This video brought back a lot of memories very clearly. Made many many recordings on it. It cost about $450 from Tweeter Etc back in 1983. If it actually is the same model we had, you could high speed dub both sides A and B at the same time. So you could duplicate a 60 minute cassette in 15 minutes, for example. First time I used that, I copied a cassette that had Linda Ronstadt What's New on side A and George Winston's Autumn on Side B. It sounded remarkably good. Other first recordings I made were of new LPs I bought...Santana' MoonFlower, Steely Dan Greatest Hits 1974-1978, Donald Fagen's The Nightfly. Used most TDK SA-90 cassette. Used Loran cassettes when I could find them...they were the best in my opinion. I'm really impressed with your technical ability here to repair this beast. I never ever saw inside it and can't believe how intricate it is. Amazing job cleaning it. Looks great!. Good luck.
Yes, a very good little deck. And her voice is beautiful for her age. Thank you very much.
When are you going to finish the repair? I have the exact same model with the "space invaders" screen
OMG. So much circuitry for a cassette deck! I know, it is a 3 head deck, but still!
Был у меня вернее у родителей отец брал в Венгрии когда служил там в 1980году короче у меня он всю жизнь был, супер магнитофон но с годами начал сыпаться кнопки сыпаться начали итд пришлось продать 😢.столько у вас сверху серебряный корпус а у меня был черный.
Unfortunately, the problem with this series is that the plastics break over time. It can be improved, and it is now possible to print fingers in good quality. Yes, it was usually the CT-3A type with the black roof.
mam pytanko ile taki sewis tego magnetofonu wyniósł, mam taki sam magnetofon i zastanawiam się czy warto go oddać do naprawy działa dobrze ale ostatnio odmówił współpracy i nie ciągnie kaset.
Hello. This repair is approx. It is between 70-90 euros.
should of removed the armature from the motor case and cleaned the old gum build up off the commutator brushes.
Hi! many Akai speakers made are made by Videoton in Hungary.
Great video. Thank you. Im trying to order tyres. FF and REF is not strong. Are there 2 or 3? Some ads have 2, some 3. HiFiEngine says in comments only one needed, some12x2.5x2.5. But I want to change all. Thank you.
Thank you very much. Well, as far as I remember there is a capstan belt, a counter belt and two idlers. One of them is in the rewinding unit, which is very difficult to repair. And the other is the drive transfer. You can see both in the video.
I have ct 3070 r , same deck but in silver face , it s one of best sounding deck i ever heard , dolby b c dbx , and most important , transport is on tooth gears , if u lubricate them once couple years it will last a lifetime
Silver-colored devices are very rare. But you're right, this is probably the last great device series from Pioneer.
@@retrodeck1956 autorevers , dolby b c hxpro , music search , and most important tooth gears transport , i cleaned mine and put some grease on them and play ....
Very nice work and video! Thanks1 Just a question.... I have an Akai GX-M10 that Im having problems closing the door... have to press hard and looks like it only closes the left side (there is a small hook inside)... Once it stays closed works well. but looking from the top you can see that the right side isn't really flash with the deck as it should be! Looks like something is jamming it (?)... THANKS for any help or hints!
Hello, thank you. As I recall, the cassette door is not built on the front panel in the gx10 deck. The front panel must be removed, then the cassette frame built on the mechanism must be dismantled together with the door. By removing it, you can check what is preventing the cassette door from moving. If it's OK, check that you put it back on the mechanics. It is likely that the door damper or springs were previously repaired and not properly assembled.
Thanks a lot for your reply… really appreciated. Actually I ended up opening the deck and discover what is the cause. I just don’t know the name of the part or neither I can see it in the manual. It’s a little still plate/lever located top center half inside … I think it’s broken…I would post a pic but not possible here! Thanks again… I have to try and know the name of that plate(small) and its function!
Thank you For video. Like it. Where corecting speed motor this deck?
Hello. There is a small hole at the back of the motor, you can adjust the speed there with a small screwdriver.
@@retrodeck1956 thank you, I thought so.. I noticed that it tightens a little when recording, maybe the small belt no good.
@@audioholmes My experience is that you rarely need to adjust the motor speed for these devices. But if you set it up, you would need an oscilloscope and a signal generator. Most of the problems are caused by belt or pinch roller faults.

Is this tube or transistor?
Transistor..
How to record on this one
The red button is recording. But I didn't test that.
What you using for polishing? Like very light compound paste ? Not gonna remove front panel graphics?
You can use any high-quality car polish. I show polishing in several of my videos, so I didn't do it here. E.g. watch the video on repairing the Aiwa Ad-450. What I used here is Menzerna Finish 3000.
Hi. I have a AD-1300 with some problem. I wounder if you can help me?
The thing is that stop makes the stop solenoid active all the time. Ends up burning the 160mA fuse
@@Brandhink Hello, yes, this is usually a problem with these devices. According to my memory, when you start playback, a switch turns off the automatic stop relay. Check this switch, maybe the control lever that activates it is located at the belt path.
@@retrodeck1956 do you have whats app or telegram or email? Would really appriciate your help 😃
@@retrodeck1956 used deoxid and moved the switch. Seems to be working. But on my switch there is a ceramic condensator. Couldnt see it on your video

Hey! I’m thinking about buying a AD-6600U to repair, do you know if the internals of this model are similar enough to that model? If so, this video would be incredibly helpful!
Hi! The mechanics are almost identical, as are the electronics, obviously the 6600 contains more units.
