Hi friends ! I am studying the circuit. I found some differences between schematic and the printed circuit board made from Andron. I found that R40 and R42 value are 270Kohm reading the pcb but 100Kohm and 100ohm reading the schematic. Continuing to read the pcb I found that U3-3 is free and U3-4 is used together to R36, R39, R43, C28 and C29. The output of apamp is connected to K18; all these are missing in the schematic. Which is the use of K18 ? Peraphs, it is a test probe for oscilloscope. Bye, Marco

I add an information that can be useful for all want build the mod03m or have built this m.d. I think that the katode of led must be connected to -3V and not to gnd as in the schematic. Bye, Marco
