LabGuy's World: 1968 Shibaden SV-700 B/W VTR

1968 Shibaden SV-700 B/W VTR Sept. 2012

       Just got this machine (exactly like the one in the first photo), number five in my collection, from Charles Bensinger. Mr. Bensinger is the author of Petersen's Guide to Video Tape Recording, published in 1975. Shown here on the right. This book was one of several that drove me insane enough to enter this hobby as a teen ager while still in high school.

       In photos #3 and #4 above, I highlight and then show one of the two video recording heads. I recently obtained a digital microscope and it is obviously perfect for the job. Getting good photos of the head tips has been an on going problem here. Check out the fascinating metalic texture of the scanner face, just above the video head tip.

       This machine is alleged operational. So, you may be wondering why the covers are off of it. Good question, sad story, really. I have a small reel of Shibadden tape that I presumed was recorded on one of these machines. I was wrong. It is recorded in the EIAJ format and thus is incompatible on the SV-700 which does not conform the Type 1 standard established in 1969.

       I tried to play this tape and of course it did not produce video, though the sound track was fine. I thought perhaps the machine had malfunctioned during shipping.

       So, I opened the case and started blindly adjusting the servo board. After doing this for a few minutes it dawned on me that the tape could be in the wrong format. DOH!

       Needless to say, I got excited and did not think. AGAIN! Happens to me all the time too! So, thanks to one of the many great friends of Labguy's World (Thanks, Radio Rick!!!), and there are SO many, a proper format test tape is "in the mail" as we say. I expect it will play back much better than my current tape. Stay tuned please!

1968 Shibaden SV-700 B/W VTR and TU-19UL Monitor / Receiver

       This model is the most common of all the Shibaden machines. All of the VTR's in this series were interchange compatible. The SV-700(U) is a two head helical full field black and white system with mono sound. The (U) suffix, in the model number indicates this a U.S. (EIA/RS-170 system) machine. The European (CCIR/PAL system) models had the (E) suffix.

       I picked this gem up with the matching monitor. I overhauled the mechanism and it pulls tape like a champ! The monitor has a broken vertical hold control which I have not repaired and tested yet.

      There are three complete SV-700U's in my collection.

      UPDATE: Some fellows, in the Boston area, have been checking out this machine to possibly use it to dub some old tapes that they have. Well, the prognosis is in. This poor machine is going blind in one eye. That is to say, it has a weak video head that may go out at any time. Now that I have a service manual, looking at the head replacement procedure, even if I had the parts, I would not undertake the task. Too complicated on this old dog ~ in fact virtually impossible without a factory fresh reference tape.

       NEW! 050313 Read the operator's manuals for these cool items: [SV-700U] Video Recorder and the [TU-19UL] Television Receiver/Monitor.
