If the waveform will not flatten then the number five guide is tilted incorrectly. As you can see in the photo top left the adjustment begins from the point where the number five guide is being raised and lowered. If the waveform would not return to peak when tested the tilt screw must be off and turned one direction or the other. This is seen in the upper right in the photo. The tape is shown as a see-through ghost image in this illustration. This is adjustment is seldom needed unless the shuttle has been replaced. It must be done to produce a smooth and flat travel of tape from the number five guide into the drum rail. At the bottom of the photo is a cut-away that shows the response of the tape traveling into the drum rail as the tilt is adjusted. Click on the photo. Once a desirable result is obtained on the scope we complete the same steps earlier described and position the other two guides again shown upper left. The lower right photo shows the number two and three guides. They are located and angled so that the tape will rise up to meet the shuttle. The guide plates can be move slightly back and forth by loosening the two screw shown bottom center. The adjustment is to make the tape travel smooth and flat as it leaves the cassette and travels on its way to the shuttle. This is important when the tape travels in reverse when scanning, etc. Also shown in this photo are some of the tools used for these adjustments and ones to come. The exit side is next and it is somewhat more demanding. Click on the photo again and here is the shuttle upper left with the tape shown smooth and flat. Adjusting the two and three guides makes this happen. They are shown in lower right minus their adjusting plates. Both are spring loaded to hold them against guide plates (which have been omitted here). The guides would collapse without the plates to hold them. There are variations in these procedures. It depends on the model. Older models can be tougher than the newer ones. This is Sonys way of doing this alignment. But there were other Betamakers. They will be discussed at the end of this refurbishing and repair study. The other manufacturers had their own way of keeping it interesting. These procedures are a generalization meant to be informative, and hopefully entertaining. Conditions vary. Now on to the next step, the EXIT SIDE ENVELOPE, click here.
