Hi out there, does anyone know what the output voltages should be on a roland JV80 power supply 1 to 5??
looked at service manual and service notes but it doesn't say. Thanks in advance, Phil.

It does say, on page 17, circuit diagram. Points are labelled A, B etc.

Hi there Madtheory, on the service notes i have the power supply diagram is on page 22 and notes the input voltages but not the output, just trying to see if the transformer is kaput and could be replaced by something else, a bit of a Frankenstein job.

Ya they're written there on that page as well: Outputs to boards on the right of the diagram: "D5V" "A+12V" "A-12V" etc. etc.

Ah, ok I see what you mean, not getting anything like those voltages so tranny must be buggered. Ta.
