( i've fixed 3 or 4 of these before. ) Hello free_electron, I've fixed a few of these myself - it's a well laid out unit and easy to work on. Does this help?: Shaper Output State Test E51 The shaper IC U401 is not able to supply positive output when -90" startphase and complement output mode are selected with triangle waveform (VCO not triggered).Possible faults: VCO (Slope) IC Al: U201 Waveform switching Al: U104 Reference voltage switching Al: U204 Amplitude DAC A2: U27, U28, U17 Refer to Chapter 10.5, Chapter 10.3 and Chapter 10.4.
