My MIDIbox CV suddenly started only putting out 1/2 the voltage that it should.

So in the calibration page, when I select 1v, my multimeter reads .5v, and when I select 4v, I get 2v.

Any ideas?

I tried replacing the shunt but that didn't work.

Any ideas?

(note: my psu is correctly putting out +/-12v)

I have no experience with this project, but when I looked at the schematics I saw the 8 pots. When I´m right, you can adjust the outputrange with this 8 pots.

There is a mathematical formula on the schematic. You should check the value of your resistors and then calculate the value of the pots.

Best regards
