Sharp gf 777

[Jwrok707]

My tape deck 2 on Sharp GF 777 plays "muffled", with poor sound . FF and Rewind do not operate at full strength. Tape deck 1 plays great but at times FF and Rewind do not operate at full strength. Can anyone give any incite as to whether this is a easy or major fix?

Welcome aboard 1st off I would have to guess that the belts are bad and possibly your azimuth needs resetting (for muffled sound) Also make sure to clean tape heads good, after years of sitting there will be dirt

Thank you my friend much appreciated.

the screws to adjust the azmuth are located just below the cassette doors .

Do you have any idea what type of screw head may be involved in the adjustment?

a small phillips screw driver it has to be very small with a narrow shank maybe 1/16 of an inch or a tad bigger.

Sorry my bad just had a look and figured out what screw head I'm working with. Thanks a lot much appreciated.

I would make sure it is not magnatized

Is there any easy way to test that myself?

with a tiny screw, see if the screwdiver will move it or pick it up

Personally, I think that before you mess with the azimuth setting, you should clean and demagnetize the heads first. Both of those conditions could result in muffled sound with poor high frequency response. Being that the azimuth really shouldn't change significantly over time once set properly and that dirty and magnetized heads is a far far far far more likely condition that occurs over time to all magenetic tape heads than the head alignments changing over time, I'm of the opinion that the azimuth setting should not be messed with except as a last resort since the proper and best way to adjust them is with an oscilloscope in order to check the phase alignment.
