Re: 405 line video of Test Card C recorded on JVC3320
Thanks for your replies folks. I'm guessing that the pulsating is a function of the damping (or lack of it) on the head drum speed servo. It only shows in playback on the 3320 and not when playing back on the FS90B.
I also tried playing the tape into a television that has 3MHz bandwidth but if there was any signal there it was very faint. My 9-90 has just the standard circuitry.
Were you running your TV166 from an isolation transformer John?
Peter.
