I've had something similar Philip. I couldn't adjust the problem out. It was a case of either reasonable audio or reasonable syncs. Getting both was tough going. Again I get the impression that material wasn't very transportable from one machine to another, so things must always have been a bit hit and miss. I remember watching whole programmes at school with the issue you have recorded for us! I don't have the schematics to hand, but there must be somewhere to monitor the pulses. It would be good to see what they look like and what level they are at compared with a working machine/tape. Have you managed to record anything on your machine yet?
