That's what I already mentioned in my message from June 26: "We discovered that the internal quadrature VCO of some A-126 does not start now and then if the corresponding control is in the fully CCM position during power on (i.e. lowest shifting frequency ~ 50Hz). But it should start as soon as the frequency control is turned clockwise. We believe that it has to do with the power on details, i.e. how fast and in which sequence the +12V and -12V turn on which in turn has to do which power supply is used and which modules are installed."
