Sony S-VHS Pro Deck
I am trying to fix a Sony S-VHS Pro Deck that had no audio. After
completely cleaning the tape path I was able to restore audio, except it has a buzz in it. Is this because the scanner is wearing out and because the audio gets recorded in the video it is the first to be noticed? Video looks fine. |

More than likely your heads are becoming worn. There are 2 sets of tracks
that are usually recorded in s-vhs, afm tracks that are recorded with the video, and longitudinal tracks that are recorded separately. Can you switch between the 2 sets of tracks to discern if its only one set of tracks that arte affected? "Michael Fiedler" wrote in message ...

I have to do some more checking, but I believe the buzz is when I am
on the "Hi-Fi" input. I will try going into the regular audio and see what happens.On Wed, 31 May 2006 17:18:43 -0400, "K `Sleep" wrote: More than likely your heads are becoming worn.

HiFi machines had a switch point adjustment. The procedure is pretty simple
but usually requires a service manual and always requires a dual-trace oscilloscope. The 30 hz head switching pulse for the hifi is adjusted so that no dropout of the hifi fm waveform is observed on the 'scope. Once adjusted, no buzz should be audible. Tape path misalignment can also cause the same symptom. The head drum would have to be worn indeed to cause any similar symptom. Mark Z.
