Reorded tapes only play out one speaker

Typically, to record on a cassette tape you must press BOTH "Record and Play" buttons at the same time and the tape recorder will begin to record.

Check the stereo Balance control. If it is set to one end, that speaker won't output sound. If found the setting to this is set to mid-point, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Your question is posted under a "CD Shelf System" heading. If you really have one of these, the answer is "you can't". The CD player is a player only, not a recorder.

On the other hand, if what you're asking is how to transfer cassette tapes to CD using a computer, there are a couple of ways. One is to connect a cassette player (boom box, component system cassette deck, etc.) to the line-in jack of your computer's sound card. Download and install Audacity, which is free software for recording and editing sound. Then you can record the sound from your cassettes as you play them into the computer.

Another option, If you want to be fancy and spend a little money, is to buy a USB cassette deck. It automatically converts the cassette audio to digital and sends it to your computer over a USB cable. Recording software is supplied (sometimes the Audacity program mentioned before). Several companies make them. Here's one from a company called ION that some friends of mine have, and it seems to work well for them. They've been converting a lot of tapes of family members, and Audacity has been good for cleaning up tape hiss and enhancing the sound.

Either way, once you have the sound in your computer and processed to your liking, you just need to burn it to a CD using whatever burning software you have. (I use CDBurnerXP. It's free, easy to use, and does everything needed for normal CD and DVD burning.)

No, it has neither a microphone or any inputs.

Look for a symbol that looks like this >I. or just this>, and push. Make sure you have selected "tape" function

Make sure the phonograph is connected to the Phono Connectors. Hook up your CD recorder to the tape. The play connectors on the CD recorders can connect to the tape play connectors on your stereo. The record connectors on your CD recorder connect to the record outputs on the tape connectors on your stereo. You can also connect you CD recorder to the VCR connectors if you are using an audio tape as your source. All of the outputs and inputs are the same level except the phono.

that means that the uptake wheel is not turning. typically this is caused by a rubber band that is insde the transport mechanism that connects the motor to the wheel.

if you are comfortable taking the device apart, you will need to find the right band and just pop it on.

My solution was to get my son to e-mail me the list of instructions that I couldn't find with my machine. The instructions, although vague, were very helpful!

Why not plug the cassette directly into the CD recorder? Are they trying to achieve some eqalization change? If not, then this should work. It's all analog at tape level.
