Re: VCM 163 problem while calibrating
Replaced diodes D1 and D2 and transistors VT2 and VT3 on the amplifier board. On switching on the needle on the mA/V meter rose to near the CAL mark. When switching from the CAL position on the mA/V switch the needle on the meter does not drop to the zero point , it goes no lower than the 1.5 mark (1/4 scale). What does this mean?
