Dual tape deck speed

Marantz Service Manual Model SD160 stereo Cassette tape deck player...


For sale for $13.99 on Ebay.

The speed should be adjustable but the common practice is to use a frequency counter and test tape or test tape and wow and flutter meter. I look at this from a Technician's point of view as I have been fixing units for 45 years so far. Once the motor speed control is found it does not take too long. Sometime it take more time taking the cover off.

to hear the audio fold back in prerecording mode you will need a tape that still has a security tab in it if not put some tape over the whole or even block the hole up

supply the tape unit with a good signal and then hold down the pause button and press the record and play button at the same time. you will then be able to monitor the sound you are about to record. use headphones as this to stops background noise in your ears and allows you to focus on the sound, "its another world inside your cans" adjust the input level until just peaking into the red. when you are ready to record leave the record button alone and the stop button and the play button just release the pause button and away you go. to stop press stop to stop recording say to cut out an advert or something just press pause.

There is a mechanism problem in the Pinch Roller part of the deck.
It needs to be looked at by a Technician to correct.

I have the same tape deck. To do a copy on this machine you first press the normal speed button below synchro dubbing, then hit the pause button on the recording side to start the copy. It will automatically start both decks.

And to stop the recording hit either of the stop buttons.

You have a broken transfer belt and it needs replacement.
This will require you to take the tape deck apart to service it.

press the synchro start button, the tape deck should now go to REC PAUSE, press the SPEED button till you get the required recording speed then press the synchro start again and it should start to record from deck 1 to deck 2.

make sure the tabs at the top of the tape you want to record on are intact,
if not just put a bit of sticky tape over holes.

hope this helps?

if paper, photocopy it, if cassette, use a cassette dubber. if you don't have one and need one, try phoning the company, or ebay or google it. www.hifiengine.com has a buch of free manuals and other paraphanalia. you will need to sign up but it's free and they don't need much information.

do you have a reel to reel deck or another machine? You may also need a schematic. Make a copy of about 2 minutes of a tape on a working machine. Keep the original in the working machine. Each cassette deck needs a different size belt. Try putting different size rubber bands on it. Cassettes usually play at 1 7/8 IPS (inches per second) each speed increases or decreases by doubling or dividing by 2.

Belts have become too slack to allow mechanism drive. Have replaced
