As for me, I have the portable Sony tape cassette player from Sony, it works fine but it's just that when I press the stop button, it keeps playing ▶️. Help. How can I fix it that won't stop playing?
Another common source of a no-audio problem in a small portable is with the earphone jack and it's switching contacts that mute the speaker when something is plugged in.
I remember getting a new AM radio as a kid in the 1970s. I plugged in the headphone and when I unplugged it, the speaker would not work again. I returned it for another and the same thing! Cheap Hong Kong junk!
You can usually tell the DC bias recorder by looking at the heads. Those, usually with the cheap mechanisms, have a pivoting permanent magnet erase head. The AC bias are usually fixed heads that move up and down with the head assembly. As for no coil on the board, unless you mean the bias trap filter, a lot of the cheaper cassette desks use the erase head as the coil in the bias oscillator.
Thanks!!! Working the record tab switch a few times cleared up the VERY loud hum from my RS/Optimus CTR-109 cassette recorder! It was so loud it drowned out the recorded sounds.
Thanks for the video. Have you any advice for a similar machine that won't record on the internal or external microphones? The playback is fine. Thanks.
I have one, speakers appear to work, then it drops out. Works intermittently. Could a dirty record button contact cause this issue? Seems like that’s what happened with this one in your video.
@ thx. I’m going to take it apart and see if I can clean it. I’m testing it with pre recorded tapes. For some reason when I record my voice on the blank, it plays back just fine. Pre recorded tapes do not seem to play back well.
My play button presses down but tape wont play, it just makes a noise & won't move & I've tried other tapes. The player is brand new too, didn't keep the receipt. I need my cassette recorder. Any suggestions.
@@JohnAudioTech the machine wheels are turning but very slowly with cassette inside but it still rewinds & fast forwards. Are both cylinders suppose to turn together? I pressed play with no tape in & only 1 is turning not both. I don't want to discard it & can't afford another. I'm very unlucky with tape machines.
Anybody old enough to remember an old cassette BLANK brand that was a darker brown color. Not completely see thru either. Probably made by Certron or some other Hong Kong brand. I've been looking for years on eBay for it. No luck. Most are black, white or clear.
I was wondering if there was a why to add a input to some electrical device when there is no input. I no nothing about electrical just thought it would be a great video if it's possible 👌👍✌️💯🎶
If that was the only cassette I had to listen to, I think I would have left the cassette player broken.
Lol. Me too. I'd personally burn that cassette
It's pretty good.
Bahahahahaha 🤣
I like it. It’s creepy. Sounds like it would be useful in a horror film production.
Praise the lord
What great timing on this video. Pressing the record button on and off a few times fixed this exact problem for me. Thanks!

Or a dirty play record switch.

This has the pivot erase head. I used to have the last base model Radio Shack recorder and it had AC bias. With external mic, the sound was great.
@@JohnAudioTech yeah. Never liked DC bias, especially on those cheap dual cassette high speed dubbing portable radio things. It sounds awful.

Praise the Lord and pass the contact cleaner.
"... and pass the bulk eraser!"
I think the transistor may have helped the sound quality a bit, I need to try that technique :)
3:47 Still sounds broken. WOW and Flutter is a bit off. 😁

2:51 hello? how did you assembly the extra parts??
Why not take a Q-tip with 90 percent rubbing alcohol and clean the tape head?? I saw my Dad do it a million times

Yes, I'd say that could be the reason.

You should record some nocopyright sounds on the tapes

Can you hear the motor running? Perhaps the drive belt slipped off.

I work on stuff like that. Not always successful, but I try.
how do i get out a stuck cassette from inside the player
Clean with contact spray

The lord, God, made them all....
Easy-breezy repair. Take em, when you can get em...
That CTR-41 looks alot like my last GE tape recorder. My bets are that the Realistic is rebadged GE.

Wouldn't be hard to tap into the microphone preamp with an input switched jack and a couple of resistors.
Oh
I hope you can analyze the circuitry of OCL504 amplifier
Many says it has a great sound😊💪
Greetings John :)
Greetings!
The Realstic sounds more Realistic!
Please use a tripod!
Hehe, a mechanical transistor oscillator.😁
U white folks use big words. I need a wife not a white woman with red feet in the back of her heels ewwww
reminds me of fnaf pizzeria sim
Not a very complete tutorial. There's so much more that can go wrong with them. Basically junk
