I bought myself an old Echo. The VU meter does not work. Measuring voltage over it in DC mode gives 9mv. Measuring Ohm over it turned off the needle goes up all the way smooth and back smooth (nothing happens in mega or kiloohm). Seems to be a circuit problem. Anyone worked with these machines before? Is the circuit inside located in a problematic position?
Everything else seems to work fine.
Schematic attached.
