meaning it will take the metal tapes giving it a superior performance in s/n ratio.
The non SP machines would not take the larger 2 hr tapes. There are plenty of those since they were popular with the news crowd where segments are 20 mins or less. And all the camcorders of the time would only take the small tapes.
Also that machine does not have DT or dynamic tracking allowing a still frame of video in pause.
If the chrominance heads are bad you will get color flashing. If colors are screwed up, its most likely a bad color filter. There are several of those thruout the machine. They look like a small silver module. They are pricey but most stations fixed them. The problem is that the adhesive glue becomes conductive.
You will have to scrape the glue off them with an exacto knife (and xylene to soften up the glue). Its about a 1 hour process. Then touch up the circuits with a soldering iron and reassemble. There was a bulletin about this.
As I remember, Sony sent a letter out to stations that they were no longer going to support analog products about 10 years ago. So parts might be difficult to find.
If you need an upper or lower drum, AHEAD TECHNOLOGIES used to sell rebuilt ones. Good luck.
