Hi saabangerman

The unit sounds like it has a take up clutch or takeup idler problem. Check all the drive assemblies in the unit. Remove the cover from the front of the transport inside the cassette well, and check the condition of the idlers and reel base drives. The counter belt can also gatherup and prevent the takeup reel from working correctly, or fire the auto stop mechanism preventing it from playing, although that sounds to be ok in this case as the unit will FF and REW ok. The takeup drive is supplied by a different drive idler as it requires much lower and more controlled torque. This unit was always considered to be a great tape deck and is well worth a bit of attention for restoration. You can get a new belt kit for $19.00 from here

I am more than happy to answer any other questions you may have about it, just give me a hoy :) Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

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.

SOURCE: My Teac Z-7000 will not record tapes

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.

Hi 1George I found a replacement belt that works but not an exact replacement. P/N FRM9.6 Flat belt from Gateway electonic in St. Louis Mo. BUT you may have to try and order it from the manufacture www.russellind.com as I had to sort thru a bunch of belts to find this one. It works great. more info. e-mail sales@russellind.com bar code # 3152-00129 Good LUCK tedglow@charter.net

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

Your new cd player/recorder is a "component piece" as is your turntable,cassette player, reel to reel or CD player. Connect it as you would any other component piece of stereo equipment. Set up your recorder to "record" in real time(not high speed or synch record). Your tape recorder records anything that is playing through your reciever to your speakers. So, treat your "CD" recorder as you would a "CASSETTE TAPE" recorder. Play your vinyl record on your turntable and record to CD on your CD recorder ! Pay special attention to the dubbing speed, you will not use "synch or high speed !! Good Luck

I have a TDK HD-01 head demagnetizer for cassette decks, but I have lost the instructions. Could you help?


Hi there.
First - Turn On The Tape Demagnatiser (should be a switch on it)
Second - Insert into cassette player
Third - Turn On cassette player
Fourth - TURN DOWN VOLUME ON AMPLIFIER TO MINIMUM (This is essential!)
Fifth - Press Play on cassette player
Sixth - After 10 seconds press stop on the cassette player
Seventh - Remove the cassette demagnetizer from the cassette player
Eighth - Turn off the demagnetizer and put back in it's usual storage place

AGAIN, MAKE SURE THE VOLUME IS TURN TO MINIUM WHEN USING THIS AS THE NOISES CAN DAMAGE SPEAKERS.

How to align head using the white plastic screw/gears


If it's a "Dragon" don't touch it! unless you've got alot of electronic test equipment to scope and meter the signal. You will cause damage to the unit. That particular model is the "only" good tape deck ever built and should be repaired by a pro. If it's any other model, it's basicly a Sony. The same rules do apply though, it's not a real good idea to guess with electronics. If it still plays well, just run a good "Tape Head" cleaning solution thru it. Generally tape heads don't get misaligned unless really jammed up. Most common problem is belts and gears. Best of luck

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.

Don't do either of those things. Just hit one of the DUB START buttons (NORMAL OR HIGH) Located right under the tape counter. The deck does the rest.
