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.

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.

The take-up reel is dragging or the belt is stretched or broken. No surprise on a deck this old. Try Fast Forward. Try Rewind. Same result?

If it still doesn't work, and it happens with only one cassette, rap the cassette's flat side against a solid flat surface to loosen it. Try again.

If you're really an old-school deck user you probably know how to cheat the transport with no tape resent to make the capstans engage for cleaning. Try that. The two reels should spin opposite as if maintaining tension. If the right one is stationary or lethargic (try to feel how strong it pulls compared to the left one), there's a loose or broken belt.

Next step. Get out the can opener, go inside and see what's wrong. Good luck.

Most tape decks have sensors monitoring the reels to make sure they're moving. Otherwise a jam is indicated. Belts usually drive the reels and they get old, stretch and/or break.

Look inside it to verify.

Using a search engine go looking for the belts for your model and maybe even find videos showing how to replace them.

That is what WE do.

How do i connect my technics su7700 amp to my technics sh8020 equaliser


Like any sound processor, in the tape loop...

Receiver Tape Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec or Line-In;


Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play or Line-Out.

How to connect my eq to my harman kardon recevier model avr-247


The following is some boilerplate I made up that should explain some usage limitations.


Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.


The connections themselves are fairly simple but it pays to understand what happens in the loop.


In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).


Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.


The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.


EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.


In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? They would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast.


Okay, back to the hook-up:


Any of the following audio connections on the HK will work: Tape, Vid1 or Vid 2.


Receiver Tape Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec, Line-In;


Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play , Line-Out.


So, to sum up, you can only use the EQ or any outboard processor for analog stereo sources. If you actually want to use an analog recording deck you could place it within the typical Equalizer

How do I link my technics ge 70 graphic equaliser to my technics cd player sl-pd7a and my technics md player sj-md100 with phono rca leads . Thank you Simon


It would help to know what other electronics (receiver, maybe?) is involved.

If neither of those devices is a recorder, why do you need to connect them to the EQ when your receiver/preamp may have the facilities to connect the two playback devices directly; and the EQ in a Tape Loop?

Scenario A)

Assuming you REALLY want to have the CD and MD input through the EQ because you can't attach them any other way...

CD audio OUT to Line In; MD audio OUT to Playback;

EQ LINE OUT to whatever analog electronic inout you have in mind.

To hear and Equalize the CD set the Input Selector to Source, EQ REC button OFF; to hear the MD equalized set the Input Selector to Tape, EQ REC button OFF.

====

Scenario B:

You have a receiver with only ONE Line Level Aux input and a Tape Loop.

Insert the EQ in the Tape Loop. Attach one of the disc players to AUX and the other to the TAPE conenctions on the EQ.

====

Scenario C

You have a Home Theater System or Audio Vido Reciever.

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.

In case I insert a tape and start playing the mashine produces atape jam.


clean the capstan roller ,head as they are filled with dust and dirt accumulated on them and cause the tape to malfunction and jam ...you can simply open/eject the cover from where you insert /load the cassette then use a cotton bud dipped in methyl spirit/alcohol and carefully clean the roller and head after you are done use the other side of the cotton bud to remove excess of cleaning agent from them ..allow them to dry for five minutes keeping the cover open and then insert your tape again and enjoy the music without any break/jam.. just don't forget to clean your head,capstan roller once a month if you listen to tape regularly..... to maintain the long life of the player ..

Hello, I have found a Sansui DA-T550 music-system with AM/FM stereo tuner, integrated amplifier, cassette deck and turnable/gramophone (placed separated). It seems like the system is working OK. My...


Hi!

I have the same deck. Did it come with rammophone or are you using your own grammophone?
I have it with original grammophone and I don't need a remote control, I don't even have it. You just turn on your grammophone and it is automatic, just place the needle on record and it should switch and play automatically. That is if you have connected the wires right (two wires for sound, one for automation, all in the same area).

If you have separate grammophone, I am assuming you just need to place two wires into the separate phono channels and it should work. There is just no automatic detection, so you have to swithc to mono manually: There is a button on the right, beside Volume control "tape to CD" or something.

To play the tape, just simply push the play button on the bottom, should work, or you could try tape to cd button off and see if it detects automatically when tape is inserted.


Currently I have it taken apart and there is tape detection system apparent. Its quite automated reciever, which sucks, because all kinds of problems appear and it is difficult to fix.

On my Sansui, the tape player starts winding slowly when pressed play button. And the tape motor seems to be on always, even when the tape is not used, and the motor is really loud. --Need to find a solution to this problem. And I hate it switch to radio/FM every time the record stops. Plus the original grammophone doesn't work correctly, it is supposed to take off the needle when record reaches an end, but it just pushes the neelde to the holder... over the record..... "screeeeech".

Yamaha Natural Sound Amp and Tape Player


All of this applies to nearly any analog consumer audio gear...

If you have any Tape Deck and an Equalizer and only the one Tape Monitor loop you should place the EQ into that Tape Monitor loop, then place the Tape Deck onto one of the probable two Tape Monitors on the EQ as it sounds like you had here...

"When I had it set up with the graphic equaliser,pressing tape monitor on the amp and on the equaliser gave me play backfrom the tape player."
That setup will allow you to apply EQ to any analog source and the tape deck in record or playback mode.

However, if you want to remove the EQ and use the Tape Deck directly on the Tape Monitor just attach the deck's Playback cables to Tape Mon In (Play) and the deck's Record cables to the Tape Mon Out (Rec). Flip the Tape Mon control to hear the tape deck or monitor it while recording.

----

NEVER plug anything but a turntable into the Phono. It has a preamp that expects a ver ysmall signal from the cartridge AND it also has a severe RIAA Equalization curve which would result in grossly exaggerated frequency extremes if you managedto get a non-LP source into it. Likewise, turntables without internal electronics mut always use the Phono section of a receiver, preamp or integrated amp to get the boost and EQ they need.
