Question about Audio & Video Receivers

1 Answer

I have a teac a-4010 reel to reel. I turned on the power and manually moved the tension arm to see if the spindles turned and they did foward and reverse. I sent by fed-ex. When it got to the shipped destination it would power on but that is all. when pressing forward or rewind/ reverse nothing happens now. Could something come unplugged or a belt come off that is not readily noticable??? Please help. Thank you. David

    I have exactly the same problem. I have it all torn apart and am about to start signal tracing. It was working fine and I attempted to rewind it and then shut it off to fix the tape. Now there is power but no drive. IDK if it is in the switch mechanism or one of the relays. I need to dissassemble a little further. If I find the answer, I will post it here.

After much frustration, mainly from working with mainly unreadable prints, I was able to locate the source of MY problem :
There are two .9 ohm power resistors on the power supply board. They are responsible for supplying AC to various motors and relays. One of them was burned open and the other was reading 250 times what it should have. I replaced both of them with 10 amp inline fuses for now. Radio Shack sells 1 ohm 20 watt resistors which should do the job. IDK what the reason is for the low value resistor.

Have a garrand 630s turntable and the switch to change the speed is stuck. any advise how to repair this?


Whoopsy daisy! The Garrard 630s is an Idler drive deck based on the (presumably) earlier SP25MK IV module. Given it's 's' shaped arm.

!WARNING!

BEFORE STARTING WORK! MAKE SURE POWER OR MAINS IS OFF/ UNPLUGGED! RISK OF ELECTRIC SHOCK.

-Remove the mat from turntable if possible. if you're lucky to have aluminium center piece, remove that. Underneath that you'lll find a cir-clip holding the turntable in place. Take a small screw driver and gently remove clip from the center-hub and lay aside.

-Now lift the platter off the center-hub or spindle-bus. You might see a big grey gearwheel which is called the cam-wheel, situated at about one o'clock. (Some models have it under the chassis.)To your left; a small, black ,rubber wheel with a metal core. Directly next to it, a two- (or three) step (Brass) pulley protruding from underneath the chassis. That is the motor but not likely your problem.

-Plug in mains and move lever to "Manual". The action should result in the small rubber wheel positioning itself against the spinning pulley and spin in opposite direction. If motor runs smooth. Switch off by moving the lever from "Manual" to "Off" and disconnect from mains.

- Now, with the power off, try to move the speed/size selector lever to and fro. If the small rubbber wheel doesn't reposition itself, something inside is jamming the lever. (and it's a long lever, running under the chassis.)

(SP module chassis, used up to 1979)

For your problem you need to lift the unit out of its plinth/ casing.
-Make sure all power's off and give slack to the audio and the mains cable. Depending on the plinth you might need to screw out a clasp holding the cables in place. Unscrew the bottom plate if possible. If not. Fasten the two transport screws which you find in the back on the left and on the right in the front.
-Make sure the arm is locked in its rest and gently turn unit over. Make sure unit is seated firmly and that you don't damage the arm!

(SP Module bottom view)

-Find the Speed/Size selection lever and try to move it... Look just below the motor and see what is happening. You see two tension springs and a "Block-like" piece of steel which should be able to move freely up and down the spindle to which it's mounted. The squiggly looking piece makes sure that speeds can be selected whilst the turntable is working. (it detaches the black rubber wheel from the inner rim of the turntable and pulley to enable repositioning without damaging parts.

-See if anything obstructs movement of parts. Look if parts are bent forcefully, warped or just worn out.

!WARNING!
Note that tension springs are mounted in the chassis at certain "values" while assembling the unit in the factory. excessive force in removing tension springs may result in malfunction or even a dysfunctional unit. Place tension springs back in exact positions.

-If necessary, take the levers apart and clean thoroughly. Make sure all parts are free from dust dirt and grease.

-Circlips can be removed using a small (magnetic) screwdriver and an old handkerchief covering the circlip to be removed so they don't launch themselves into oblivion.

-Number parts (small stickers) before dissasembling counting up. Reassembe counting down again.

-After degreasing: apply tiny (!) amounts of Singer-oil on parts that may cause friction with eachother... Keep in mind that applying dabs of grease may result in decreased performance when the wrong oil or grease is used.

Happy fixing the Garrard 630s.

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.

Will not drop 45's


I think the spindle is broke or stuck in some way! if you have another one try that! and if you dont you may be able to use those little plastic adapter thingys and place them on the 45s and try that !
It sounds to me like the spindle is sticking and is pulling the turntable belt and slowing it down!
I would look for a new/used spindle
I think this will fix ya!

I have a pioneer RT-909 reel to reel unit. When the playbutton is pressed,the motor starts the tape then it continually stops. I'm assuming that the motor or belt(?) is bad?


Hello I had the same issue the take up reel tensions need to be adjusted try this thread tape so that there is no slack hold one of the tension guide reels try the right one first hold it so that it is in the 12 oclock postion this is so that it wont retract to the left which will prevent the motor from stopping or going into the cut off position if it continues to play with you holding it in this position the the tension for the reels need adjusting this can be done by slightly turning the blue adjustment knobs that read PLAY / TU 7 FWD 10 one is for 7 inch reel and the other is for 10 inch reels it's the board at the very top of deck when you take the cover off turn them slightly to the left until problem is gone this is what I did and it worked

TEAC V770 3head tape deck. Does not play. Pinch roller spindle turning. Press PLAY and heads click up,forward tape cog does not turn, heads go down. Manually turning forward still does not work. FF...


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.
