My Teac Z-7000 will not record tapes

My Teac Z-7000 Master Cassette Deck will not record tapes. I have the manual and know the procedure for recording, but when everything is set up and ready to go...I press the play button and it won't record. The tape does move. The level meters go to zero. When I press pause, the meter levels start up again.
The unit plays prerecorded tapes fine.....and what a sound!!!!

Any suggestions?

    dgd21ro,
    I got a manual on eBay. Once in a while one will show up. Is your
    problem with recording, or is it in playback? (Does a prerecorded tape
    exhibit the problem, or is it just manifested in tapes that you record?)

    Thank You witke64 my problem is solved!
    I replaced the fade in pot with an Alps RK097111T064 100K Flat 25mm unit. The phone volume pot with an Alps RK097122T017 10K Flat 25mm dual unit. (The 10K works fine for headphone volume control) I procured these from Mouser Electronics. They have an excellent catalog with good details on all parts.(www.mouser.com). The original pots are obsolete and no longer available. These were a close fit, but not perfect. I was able to grind out the insides of the knobs and epoxy them to the shafts of the new pots. The new pots do have the push in and out feature.
    My Z-7000 now works perfectly!

Hello,
some weeks ago I got this really impressive deck (Teac Z 7000) from a colleague, and found the same problem. I fixed it, and the fix is not too complicated. It´s the potentiometers that do fail. All pots are from the same manufacturer (Alps) and construction. The problem is that the wisher is broken away from the holding plastic and will loose contact completely. You can check that with a normal ohmmeter: You´ll find the total resistance over the outer terminals but endless resistance from one of the outer terminals to the middle wisher contact. The values are: 100 kOhm linear for each of the upper left pots (fader,space), 2x22kOhm pos.log. for the lower left pot (phone volume). So, what does a broken wisher at the "fade in" pot do? The Recorder "thinks" that You selected an "endless" fade in time, and the result is : no record level. You can do an easy "quick and dirty" fix just to see if that´s the problem: Hold- or better solder- a say 47kOhm resistor in parallel to the conducted potentiometer terminals and try to record.
4 of 5 pots have been defective in my deck, and I´ve replaced them with standard types from my local electronic supplier (Conrad electronic, has a shop in Frankfurt/Main). Well, the new parts didn´t fit perfectly, I used a file to get them in (not visible from outside). Also I lost the possibility of pushing the knobs in and out, but that is not a really problem.
I assume this fix might also help owners of the Teac Z-6000 and Z-5000, which- most probably- use the same type of potentiometers.

your receiver has (or should have) input and output connections,, your turntable needs to be hooked to the receiver,, then with the output cables that feed your cassette player you need to go, in to out and out to in ( receiver output to the input of the tape player, and out of the tape player to the in on the receiver, while playing a record if you hit record on the tape player it will record the record, depending on the receiver it will show you the meter readings for either the in or out,, they vary

Is there a diagram on how to replace the drive belts on this casette recorderplayer


the short answer is "NO", but the good news is that you can find these belts. First take a photo of the inside of the deck so you can see where to put the new belts, (or make a drawing) now take the belts out of the device, if they are broken that's ok. take the belts to Radio Shack, they have a catalog there that will have drive belts in it, you can compare the belts with photos in the catalog, you can also measure the belts, but it is easier to match photos for the correct size. Another option is to use the make and model of your device to do an online search for parts. Chance are with a cassette deck it is most likley not being manufactured anymore and parts will be hard to come by. I admire your desire to fix it, these things are getting rare, one other thing I just thought of, is to try GoodWill stores, they may have an old cassette deck that you could buy and use the belts out of it to fix yours, (salvation army too) or yard sales, that's where I get a lot of vintage parts. You can also try your local TV/Radio repair shop, many have a large supply of msc belts for back when they used to fix this stuff. they are out there, you just have to be diligent in your search.

Does this recorder have its own amplifier?


Sure, the tape will play.

Copying tapes does not require an external amp, but LISTENING to them might. The A-4010 has a headphone jack so you're good to go with headphones alone if necessary.

To record, Connect the Output from the new deck to any Line Level Input on your recording device - (NOT PHONO).

If you can, set your record levels up in advance being careful not to have them too high if you're going digital as overloads are not handled well.

As with any old, rare or prized open-reel recording, avoid excessive transport handling of the tape, especially rewinding at high speed. Get yourself some Q-tips and isopropyl alcohol and clean the deck carefully, especially the capstan and idler wheel. Cheat the two tension levers manually and press Play. The capstan will engage the rubber idler. Clean the roller first with a moist Q-tip, being careful not to get strands caught up in the capstan (I'd hold the Q-tip around the 3-o'clock position on the idler), until you get nothing but a little black from it on a clean moist Q-tip. Then press Pause and the roller will retract but the capstan will still spin. Clean it with a fresh wet Q-tip until it is shiny and no more color comes off it.

Handle the reel without placing any inward pressure on the flanges as edge damage can occur.

Make your best stab at a transfer in as few tries as possible as the tape oxide and base are very old and will not tolerate repeated playbacks. Run the tape completely in one direction, flip it over, CLEAN THE DECK AGAIN, and play it back in the other direction (avoiding REWIND as it places a lot of stress on the tape and will probably leave the tape wound unevenly with edges sticking out all over the place. A normal speed playback should wrap the tape nice and tight and even for storage. Avoid exposing the tape to high humidity, dust or heat.

If you have access to a CD Recorder, I recommend making a full resolution Master copy on it and using the digital copy for any subsequent copying, ripping, editting, etc. Archive the original tape and make a digital copy of your end results, too. Good luck.

I'll make this offer to you. If you get it digitized and onto a CD I can probably reprocess it to clean up tape hiss and other problems inherent in 70's-era taping. Analog tape recording was my passion and still is, but I save everything digitally now.

I was following instructions for "Recording." On the next page were instructions for "Tape Copying," though the first page began with, "Load a tape for recording in Deck II." That sounded like what I wanted. Anyway, that was my error.

Vcr recording


See page 10 of the manual re connections
The vcr (or DVD hard drive) you want to tape to has to be plugged in to the sockets shown for "video cassette recorder"

I select TV/DBS and hit play on the from vcr.
