I just had a pleasant phone call from Steve Deming and he told me something I did not know even though I have had the Yam 9000 for a couple of years.
You can email them directly: ycasupport@yamaha.com
YOu can phone Steve Deming and his people for support at 714-522-9000. That is in the Los Angeles area.
No I don't think they accept collect calls
I also want to thank Dan O'Neil for asking Steve to call me regarding a problem I was trying to resolve. See my other post this date.
Best to all
