Re: VCM 163 problem while calibrating
I have now gained access to the amplifier and oscillator circuit boards.
First things I checked on the amplifier board were D1 and D2, one of them has failed. I have ordered some new diodes and some new transistors and intend to replace the existing ones.
I did get the correct signal at the RED and BROWN connections on the oscillator board.
I will report back as soon as the replacement parts are fitted.
