Re: Dub TBC

you have a very old 3/4" VTR. You know that 3/4" has not been made for many many years. The VO9600 was a player, not a professional VTR. To get the "perfect image" you want, you will need a 3/4" VTR that can work with a Time Base Corrector -not a frame synchronizer. This means that you need to send advanced sync and subcarrier (and the heterodyned video out of the 3/4" VTR) into a TIME BASE CORRECTOR that can provide ADVANCED SYNC (a 2.5 V Pk-Pk signal, not black) and external subcarrier.

This "package", which used to cost over $20,000 was the BVU-800 and the BVT-800 from Sony. Over the years, Sony made many models that could do this, like the BVU800, BVU820, BVU850, and TBC's like the BVT800 and BVT-810. Then, as technology advanced, they came out with all in one models, like the BVU900, BVU920 and BVU950, which had TBC's built into them. External TBC's that were true TBC's and not Frame Syncs were made by Microtime, Fortel, and others, all long out of business.

The VO-9600 is not one of these VTR's, even if you had the correct old TBC from Sony. You should be happy that you can get any decent image from the VO 9600 and your Snell Wilcox Frame Sync. These are all antiques. It's a miracle your VTR is still working.
