Question about Teac A-H300 Amplifier

1 Answer

Only two of my amplifier inputs are outputting sound correctly!

Hi,

My TEAC Reference 300 amp has developed a problem over the last few months. Currently, only two of the inputs (the Tape I/II) are working correctly. When the CD/Tuner/MD or external sources are connected to any other inputs, I only get sound out of one of my speakers.

Can anyone suggest anything, or should I simply try and find a new amp?

Thanks for your help!

Rich

Odd one! Normaly you would loose a channel if the main amp was down, or the pre-amp was. But clearly the main is working. The only conclusion is that there must be more than one pre-amp and that's why the Tape section works. The only way to solve this one is to go inside and trace the imputs to where they join the PC board.
A helpful hint is that if you touch the audio section with a srewdriver, it will buzz! And since you have two channels which copy one another you can work out where the fault is. Because if it buzz's in the good channel, it should in the same place on the bad one.
WARNING don't stick your srewdriver on power parts, and don't short any part out with it.

Install a equalizer to Teac Ag D9100 Receiver


From what I can tell (from photos), you'd hook an equalizer in the Tape 1 or Tape 2 path, where the EQ takes its input from the receiver's Tape 1/2 output and the EQ feeds its output to the receiver's Tape 1/2 input. When you want to switch the EQ into the signal path, you just push the tape monitor button for whichever tape path you hooked up.

Why doesnt audio go to the receiver


There may be a cable that isn't passing audio any more or the amp in the tape deck isn't working.

Teac x-1000r tape skewing off pinch roller


In the Teac X1000R this is most often caused by dirty Pinch Rollers and secondly bu a ring of oxide or a wear mark being developed into the capstan shaft. If cleaning the Pinch Rollers does not do it then a trip to the technician is required. These decks also have a touchy servo tension system that if upset can also contribute to the failure of this kind. I still work on these in Chicago area all the time. Russ the other ex-Teac guy is in New Jersey. Be careful of local shop with this model as many of them turn up the servo tension to resolve this problem which is the wrong thing to do that then burns out parts and the cost goes up. I have seen this mess many times as people bring me these decks as a last stop-- of course I fix then correctly with the use of the Tentelometer as is required. Pinch Rollers are often reconditioned with Naphtha after cleaning then with Denatured alcohol.

I have a TEAC AH300 stack with tape deck, cd, etc.. It's about 13 years old work perfect. Can I connect to iPod an listen to music through the TEAC?


If it has aux or audio input then yes, you will still need the docking station to the type of inputs that are available on the Teac. It should all be line level.

Teac AG-V8060 Receiver No sound. If I turn up the volume all the way I get a whisper of sound from the speakers.


NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through defect or idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

Need to know how to replace belt on Realistic TR 300/ Teac X3


I think they are replaced through the front as in this design the face panel is removed and the capstan and flywheel are there in sight. I did a few of them some time back but my memory is not that fresh on the process- I am sure I could do the job if presented the deck. I have been working on Teac decks for over 40 years and was Lead Technician at the Chicago Factory Service facility in Arlington Heights. The service manual with parts blow up can also give indication of how to go in if you never worked on this deck before.

SX-1600 + KD-491F


Appreciate the additional information.

To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.
