Sony tape player
Hi,
Ive got a sony audio tape player, must be 18 years old or so. Ive still got tons of cassette tapes and still like to play them but find that , one by one the cassette side of my radio cassette players begin to fail. The radio works ok, but the motor seems to go in the cassette players sooner or later. So Ive turned to this little sony tape player, it still works great. It runs off 2 aaa batteries... each 1 and half volts. Ive got about 6 elec adaptors, Ive tried them all on the sony, taking the voltage down to 3 volts dc of course... but no joy Ive changed the polarity too , they just dont seem to get it going but slip 2 aaa batteries in there and it runs a treat anyone explain why I cant get one of the six adaptors to work it ? |

Presumably the tape player has a DC in jack? Are you sure you have the correct size plug on the adapter?
One "problem" that may catch you out is the inner diameter of the plug. If that is 2.5mm and the pin in the socket on the player is 2.1mm the plug will physically mate with the socket but that 0.4mm difference means there is no electrical contact. And there is of course the possibility that the socket is broken. |

Thanks for the comment. But each adaptor usu has a four way socket on the end
So you d think I d be making contact with one of them But you re right. The socket size could be the prob |

2.5 and 2.1mm are two very popular sizes so very likely the adapters have both. Though nothing to stop Sony using their own size!
And as I said it might also be a broken socket. If the socket is the type that switches the battery feed off as you insert the plug then since the batteries still work it suggests it may be the ground pin that is faulty. Two very common faults are a dry joint and a broken contact pin. With a dry joint the solder doesn't flow properly round the pin and make electrical contact properly. Sometimes a gentle wiggle on the plug can move the pin enough to make contact briefly. Easy to cure with a soldering iron to remake the joint. But I have also seen these type of sockets where the contact pin breaks where it enters the body of the socket. Only remedy there is to replace the socket. |

That sony is probably on its last legs,
I dont have the will power to start operating on it with a soldering iron. Ive just moved a big music centre into the kitchen one of the two cassette players on it still works... for the time being..... the cassette players on so many radio cassettes seem to have a built in self destruct system... I must have about 6 now that are defunct. |

Why not get a proper deck from ebay or the Heart Foundation. For £10 I got a Denon deck and the sound is excellent. It is rugged too so just keeps on going (like it has since 1985).

Once they get a bit of age on them they generally aren't worth repairing, even assuming the parts were still available - basically you need to replace belts, pinch rollers, rubber tyres/wheels, clutches and the worn out heads. |

Ive got a fab Pioneer music centre, the left hand
cassette plays tapes... the sound is brilliant the right hand cassette player is caput.... thats the one that records too so I cant record any of the fab music I get on this high class music centre. A good tape deck is prob the answer Ive got an Arcam system too ( minus a tape deck ) Its always these tape cassette systems that conk out modern systems prob have digital recording onto hard drives...... no moving parts ! |

HDD's have moving parts, and HDD's fail.
Some car based HDD's are actually SSD's masquerading as HDD . SSd's are the ultimate in reliability . |

the old video recorders were moving parts... they were choc full of cogs and motors to keep that huge video cassette going
all that machinery has been replaced in modern DVD recorders just like the old fashioned typewriters were replaced by word processors..... things have moved on. My tiny mp3 player plays audio files... cant think theres any motor whizzing about inside there ! |

Very very rare in PC modern systems and unheard of in stand alone audio players
![]() A LOT depends on the manufacturer, Quantum and Seagate are probably the worst, with Hitachi and Samsung probably the next worst - WD seem pretty good, and I always fit those as replacements if I can. HDD usage in audio recorders is very minimal, so I've no idea what sort of failure rates those incur, but as they use the same drives it's going to be pretty well identical. Quote:

Never ever had a Samsung drive ( or a Samsung ssd go down ) and I have built / serviced "so many" PC's . When did you last see a ide hdd ? "pre historic" LOL
I did have a few WD drives fail but that would be circa 1997 ! in modern PC that are mainly used in offices or domestic homes its is truly very rare to see a failing hdd . |

I still use cassettes the main issue is the belt will eventually need replaced I have got a vintage 1968 sony TC 50 which still works after replacing the belt. |
