Roland fr-3s service manual

[Caps]

I bought some from Mouser electronics. I think Jameco has them too. Have to look close at them as the pin housings are of different shapes. Two holes are "D" shaped and two are Square. Some Molex connectors are different.

Most likely it is the jack board. The previous owner apparently pulled on the audio cable when connected. These audio ports usually crack and no longer operate properly. They are not user replacements or cannot be purchased from Roland. Unless you are a certified technician.
A good solder person can replace them. Someone on this forum may have the part number of these output jacks? They usually show these part numbers in Service manual, if you have one.

Sounds good, thank you,

Sounds good, thank you,

It will probably be called the phones board in the service manual.

Hello,
Concerning the FR3-x Battery wiring, what I see on the manual is that :
- 2 cables are used with a middle Connection on a metallic support (I imagine to enable the unmounting of the Battery pack)
- 2d cable is connected to the 3-pin Connector CN2 on the Amp. Board. (Only 2 wires used)

and for information, as already posted, you can get all Roland FR Service Manuals (and other brands ...) on following site :

Thank you for this link! I contacted them and was able to purchase an actual FR4-X service manual with schematics. It was 11 Euro via paypal plus the paypal fee. It was delivered within the hour via email link. Big file - almost 20 Meg.
