Do you know where you can get parts for these. Marantz doesn't supply parts anymore, nor does the company they sold the pro division to. Very poor!

This is going to be a tough one. Your unit was made between 1992-1995. The Yard Pro brand was used by American Yard Products (AYP) for lawn and garden tractors sold in the early 1990s. Swedish conglomerate Electrolux purchased the Roper lawn and garden division in 1989 and renamed the group American Yard Products. Lawn and garden tractors were sold in the USA under the Yard Pro, Rally, and Rally Plus brands until 2000 when the division was again reorganized. By 2006, the former Roper production was fully merged into Husqvarna.

I think your best bet is to contact Husqvarna coustomer support

it's by email. Geer

Best to you

The Marantz brand was sold to another company. That buyer does not have the technical documentation for the 720. You would be hard pressed to find simply the user manual unless in a forum query or Ebay . I have not found such, rather only references to manuals being with a unit for sale on occasion. No have I located online diagrams or technical support for the unit. If in working condition, it has value of several hundred dollars. Whether any internal belts are viable or replaceable is a question. The buying company has no parts for this machine. That said, here are a couple of possible leads: http://www.mineroff.com/marantz/service.htm

No use in me directing you to the company site. They have nothing there for this machine.

A high quality fast response Servo Stabilizer will solve the problem but mark my words highlighted

It would help if you first find some pictures of the actual tank, then you could try contacting this company: http://www.model-supplies.co.uk/ or other companies that make reproduction decals for models and old toys. The Maidenhead Static Model Club is another possible contact point for you to try. Good luck!

maybe a division of? Rich people??lol

I would not be surprised if it does have bad caps in the power supply section.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

It was never sold separately, so I don't think your ever going to find one.

To online companies sell spares for Marantz. They are: SEME and CPC.
I also seen belts sold on E-Bay.

where you able to find parts, i am looking for a new regulator

Hi wangkatja

There is little that the user can do to introduce hum to a pro recorder like this, so it will not be something you are doing. Does the unit still do this when you are recording from batteries. If not, this would point to the power supply having poor regulation. If the gear is brand new, I suggest returning it to the supplier and get them to sort it out for you. Marantz service is generally pretty good.
