Problem with recording/playback


If it plays back a pre-recorded tape OK, then the tape head will be good. If it doesn't you might have problem, with either the head or the pre-amp stage.
However if it is playing back OK but not recording, then you have problem in the record circuit. Some tape decks physically switch the circuit when you press record. Pushing the record button will cause a switch to move position. In some cases dirt or dust can get into the switch and it doesn't connect properly. Switch cleaning fluid will correct the problem.
However the record circuit itself could be faulty. Perhaps an IC has developed a fault on one channel, which will need to be replaced.
Watching what happens when you press record with the top cover off, showing the workings, might point to some movement of the mechanism to reveal a faulty switch.

One channel output louder than the other


switch the outputs (L&R) from the cassette to the amp or receiver and see if the loudness changes speakers if it does then you have a channel going out if it don't then change your wires with new ones, the jacks sometimes go bad also (that are connected to the wires)

When converting tape to itunes on my MAC, sound is coming out from right channel only. How do I get sound both the left and right channels?


It's most likely a faulty connection, be it plug or wire between one of the machines, or the channel has been switched off somehow.

When I put it in a power supply the audio meter is pick , even if no signal is fed to it. why is it behaving like this?.


when the power is feed to the palyer it sends electric current to all the components and there is a sudden shock which is responsible for it.it is not a problem if your player is working fine.my sony deck reacts the same.

Kareoke machine. cd fine . tape no sound


With audio problems if you look inside the unit, start the machine playing, then trace the wires from the tape head to the PC Board, then all you need do is touch the wires from the head with a small screwdriver. This should cause a buzz in either channel, if working right. Follow the circuit of the audio and keep probing. If you get Buzzing sounds near the output, and where the wires from the head enters, then there's something up with the head. But check for micro switches these can break and bend out of place so the sound is cut off.
If you get no buzz at where the head wires enter the PC Board, then there's a fault in the audio section.
As both channels are out you are looking at something common to both channels, for instance an IC.

Tacsam DA 30 has no playback


Chances are that pre-amp IC that controls both channels has failed. Follow the wires from the tape head and trace the signal. Better still start with the output of the deck and trace backwards. If you touch the audio circuit with an insulated screwdriver (don't short anything) it should buzz. when you find something that buzzes on one side (coming out) but doesn't buzz on the otherside (signal going in) then you have found what needs to be replaced.
PS don't touch the power section.

Sony tape decks model tc-355


Follow the left channel lead to where it joins with the PCB. Use a pointed tool and prod connections if you get a buzz then that stage in the amp is working. I suspect you will find it leads to a IC that might cause the fault. If you find it buzzers on the right but not left, then it's gone. PS don't short pins. If you can get hold of a signal injector it will make things easy.
Be careful and good luck.

Nakamichi CR-4 Only Recording on One Channel...need help!


Hmmm.....heres a really stupid question but........is the head clean ? There may be a bit of oxide shorting the one side of the head out. Try cleaning the head with a q-tip and some 99% pure isopropyl alcohol. If you have done that ( you seem to be more knowledgeable than most ), I would suspect either the circuit that drives the right channel record head, or the head itself. Is the head running flat against the tape?. Is there a record/play relay or record relay somewhere in the circuit ?. I think at this point you really need a schematic. Do you have the AC oscillator signal ( bias ) present on the right record head ?. I would try this first, then look into a manual.......Good luck...Rob
