Stereo Reel to Reel Tape Recorder

add a review (1 review)



Automatic Reverse and a special Counter Repeat mechanism allow the A-4300SX deck to run for hours. Or days. Without attention. It's great for parties or whenever you want non stop music. And the other exciting Teac features we've built into the A-4300SX will give you non stop pleasure and enjoyment as well.

All Teac reel-to-reel decks are built around our famous three motor transport. We use one motor to drive the tape past the heads at a constant speed, and one additional motor for each reel spindle to provide take up tension and rewind and fast forward torque.

Six feather-touch push buttons activate the transport system electronically, making it easy to maintain total control over transport operation. You can switch instantly from Fast Forward to Rewind, or from Play to Reverse Play, with no danger of breaking, stretching or spilling your tape.

In addition, a special punch-in recording feature lets you go from Play to Record while the tape is in motion. A double safety system prevents this from happening accidentally, but whenever you want you can utilize this feature to create a running splice.

The six push buttons that control the transport are duplicated in our optional RC-140 Remote Control unit. When connected to the A-4300SX, all transport operations can be initiated from
up to 16 feet away.

One of the features our customers seem to appreciate most is Automatic Reverse. It doubles the playing time of any stereo tape, and allows you to sit back and relax. When the music stops at the end of Side One, the transport automatically reverses the direction of tape travel and begins playing Side Two.

This is a beautiful machine. I purchased mine new in 1977 when I was in the Army in Heidelberg Germany. I still have my machine and use it quite often. It is 100% reliable, and I must say I have never had a problem with it. Three years ago I did take to a local electronic repair shop to have the dials cleaned, a belt replaced ( even though it didn't need it) and to have the entire unit cleaned. This machine cost $460.00 new in 1977, today you can find them on ebay for anywhere from $100- $800 depending on the condition of the item. If you decide you want a deck, this is the one to have, I love it as much now as I did when mine was new. I am not going to list all the technical stuff, and I did upload a Color brochure, and instructions for this machine many years ago.... so the tech information is available on this site.



re: A-4300SX

I had mine in clean and dry storage. Just pulled it out after not using it for at least twenty years. It powered up and with the exception of some scratchy spots on the volume pots, worked flawlessly.
