Its a fairly easy job to replace the mains transformer so you don't have to use converter/transformers. Everything after the transformer is the same on all models, so see if you can find a 240volt input version with the same output voltages (taps) these should be in the service manual, or you can simply m,easure with a meter, and away you go. Makes for a much cleaner job

This deck looks so much like the CT-f2121 deck I got in 1974. Not the greatest of tape machines but all I could afford that year. I ran that sucker into the ground makin' tapes. I hated that freakin' slanted cassette well and door combination. Ejecting a tape with the door shut was a PIA. Not made any easier while stoned or drunk. Interesting model this CT-50T. Um, does the clock work with power off???

I have to say you did a smashing job :-D The old fully metal decks are really good quality. I've repaired a fair few tape decks, but most are crappy weak plastic. Maybe that pop was the auto stop pcb shorting on something. Old philips decks are horrible, the belts turn to black tar, hell to clean off :-(.

For me this is by far the best Techmoan video, seeing a competent DIY'er but non electrical engineer making this repair (mistakes and all) is an inspiration. I've had a pristine (bar belts) Nakamichi BX-300 sitting on the shelf for almost a year in need of replacement belts and thanks to seeing this I've now actually ordered the parts and will attempt the repair myself. I understand the time and effort you put into this video must be huge, thank you, please consider doing more like this, I could have watched for another hour!

One rather important point..... A lot of cheap replacement belts are so poorly made that it is a big mistake to fit them because they will cause a bunch of problems including wow and flutter. You would think a belt is a belt is a belt....alas, it ain't so. Pay the extra few quid for a decent quality belt. You might try Russell Industries, (russellind.com).

I adore those cassette control levers, the feel when you press them is one of the best I’ve ever experienced in the hi-fi world. I used to have a Pioneer CT-F2121 cassette deck, it looked almost same as this one without it's nice watch. I was very sad when it was stolen.

Dear Mr Techmoan I enjoy your vids.But never use isopropanol on pinch wheels as anyone from pro audio will tell you (It is fine on tape heads) Use very dilute Fairy Liquid in water or other detergent as isopropanol can make the soft rubber brittle over a period of time . Keep up the good work!

Hi ! Half an hour video on repairing a cassette recorder including errors and dead-ends isn't too bad. If I had filmed the ups and downs on the Pioneer RT-909, which had to recover from 15 years of damp cellar storage, rubber parts turning back into crud oil, dead capstan motor and previous repair "attempts", I would have needed a few hour-long sessions. The current very stubborn and used-up Marantz MA-5 monoblocks would potentially end up in a series like "Project Binky", which was estimated to be finished within a year or so ... and took four years as of now with no end in sight. You did a good job - not only for someone doing it a first time. And you should buy one of these cheap chinese µC-controlled component testers and attack the electronic autostop problem. You'll make it - there is a good checklist in the comments. :-)

I’ve messed around with a few Pioneers of that era. They all have wires wound around the contacts and I never understood that either. They seem to have a decent connection though, so I just leave them alone. That square belt threw me for a loop, the cassette drive mechanism I worked on has a flat belt like the one in your replacement kit. Thanks for all your content! I’d love to see more like this!

You should try "rubber renew" on the components like the pinch roller and maybe some belts ect. when you're just trying to get it going with the original rubbers. Phono guys use it with good success.

I can't believe i watched the whole thing. seriously tho, great vid. enjoyed. I agree with @countzero about the autostop, prolly lytic/aluminum caps at fault or maybe the transistors. those caps are easily replaced....so are the poly caps....if problem no resolved by replacing the lytics. in the vid at the point you show it i stopped the vid and tried to look carefully at it....wondering if the larger of the two blue caps looks poofed a touch? love to see a followup someday.

There is a down-to-earth quality about having the guts to show the whole process of trial and error. But that is really what we learn the most from, isn't it?. There is another down-to-earth quality about being able to learn from other people's mistakes, without doing a Nelson Muntz "Ha-Ha!" afterwards (The Simpsons reference). - Remember the 1955 time-circuits replacement from Back to the Future III? - That is what that auto-stop PCB looks like to me. Sort of an analog component version of what would have been done with a bunch of digital logic 74xx IC chips, only a few years later on. And I bet most of todays electronic enthusiasts would be showing a few veins on their foreheads at the thought of having to resolve the issues on that PCB - Unless of course you're somebody like Mr. Carlson. He would eat if for breakfast, enjoy it like Garfield munching down a lasagna and then he'd be asking for more: https://www.youtube.com/channel/UCU9SoQxJewrWb_3GxeteQPA

I have to agree with the other commentors that this was really a fantastic video. Along with your prior repair videos, but especially this one, altogether they have given me a ton more confidence in my ability to attempt to repair similar type components! Items that I would never have thought to open up a myself previously I now can look at and reference your videos and at least get some ideas as to what could be causing the problem and more importantly how to fix it. So I very much appreciate you sharing this video with us. I'm sure I'll be coming back to it along with your other repair videos in the future. Many thanks!

Hey Matt, a pro tip for you. You are using wrong screwdrivers. I was there too, used one Phillips screwdriver for everything and quite often found myself stripping screws. Never use smaller screwdriver than what it is intended to be used on. What I mean by that - you can undo and redo PH1 screw with PH0 screwdriver, but you are going to strip the head. If you use PH1 screwdriver on PH1 screw, you will almost never strip the screw head down. Also, don't use cheapo chinesium screwdrivers od bits. It is just not worth the time or money. And also, choose screwdriver with good thick handle. Those thin toothpicks with no thickness are really bad to use because you have almost no grip and it usually jumps and destroys the head.

The Staar S.A. patent is for auto-stop? I always wondered. I've seen "Built under license from Staar S.A." written on many newer decks but they never say what it's for and a basic internet search doesn't turn anything up. One thing to try before giving up on rejuvenating idler wheel rubber is to use automotive brake fluid. Brake fluid causes rubber to swell up and soften a bit which often is enough to get the mechanism back in service. Of course this is not guaranteed to last very long, more a trick to use to quickly recover a tape or something when all else fails, but it's worth a shot if you're desperate.

Wire wrapping was a very common way of wiring electronics that dates back even earlier than age of your deck. It showed up a lot in old computer systems as well as other electronics such as stereos, amps and decks. To deal with your auto stop you would need to know some electronic theory and would need to understand how that circuit is supposed to work. It is not surprising or a cause for discouragement that you don't know about it since you haven't had the electronic training you would need. You do very well for an "amateur."

With your automatic stop circuit board. You do have the knowledge and digital multimeter to test each component on that board. It looks like a very simple board to work on. Believe it or not I only know about as much as you do! #1 test the diodes, that they only conduct in One Direction. #2 check capacitors and see if they are bad or leaky. ( #3 check resistors to see if they are within specs. #4 look up the transistors numbers. Like your C 1419 it is a NPN transistor. Right off hand I don't remember how to test it. With Google you could learn it in 5 minutes & test it using your multimeter. Test your small transistors. That pretty much covers 99% of everything I'm that bored. The other 1% would be the solder joints and any circuit board trace. YOU CAN DO IT TECHMOAN! 👍👍🤔

About belt: if you can't find a belt who fits your deck, you can easily print it with a normal 3D printer (I have a Creality Ender 3) and a flexible TPU filament. I did it for one of my Sony Walkman, the WM-EX678 (it requires a belt with only about 0.5 mm of thickness). I can't say if it will be last forever or at least it has an average lifetime, but if you can't find a replacement, this is a good way to replace the belt.

Hi Techmoan, just getting around to your vids that have come out in the last few weeks. I guess you're aware of JIS screws? They look like normal cross heads but have a punch mark between two of the cross points. If you use a Western cross head screwdriver on them, they will round off because the western cross head is designed to 'cam out' of the screw, whereas JIS screws are not designed for this. JIS screwdrivers can be bought on ebay. As the owner of multiple Japanese motorcycles over the years, I'm quite au-fait with this difference in Japanese and Western tooling and fixing. Hope it helps if you didn't already know! :)

send the board to big clive, he'll mend it for your. Best guess the C1419 power transistor has failed or has bad solder joints. Next would be one or more of the little black transistors if the C1419 is ok. It wouldn't hurt to replace the 5 electrolytic caps as the green ones should be ok and it's very unlikely the diodes or resistors have gone bad :) just a thought :)

If you get o-rings, try to get the green HBNR (it's hydrogenated nitrile rubber) ones. They handle tough conditions, like heat, ozone and solvents better than black nitrile or natural rubber. I don't know about their friction characteristics, as I only have experience from an automotive perspective. Often sold as Air conditioner o-rings. I also don't know what they are called or if they are green outside the US, but still should be found as automotive AC o-rings, as they are the cheapest thing that can handle such conditions.

Probably you know but when you want to find out whats causing wow and flutter, you want to know the cycle of wow. It's hard to measure single up and down precisely. So measure like 10 and devide by 10. After knowing the cycle what you have to do is put a dots on anything that turns and find out the cycle of each approx the same way visually. Same cycle one is the guy. Oh, I enjoyed the video great deal.

Wire wound connections were quite common in that era. Quite reliable when done properly. I think Solder was expensive so they were looking at cheaper ways. Also, wire winding machines could automate creating all those connections, where soldering would still have been manual back then.
