I am also looking for the schematic of the Micronta 22-220.....unfortunatley I cannot read the values on your scanned image....any chance you could make a higher res scan or tell me the values of R14 and R19?
Hi, there . Does anyone know where can I find, for replacement, both zero adjust potentiometers ? Both parts of my Micronta have serious bad contact. i have already tried to spray contact cleaner, without success. Thanks for your time.
