Today on the bench, an Amiga 600 that had a recap but the right audio signal is not as loud as the left channel.
The problem

Left signal has voltage level of 1,32V, right 680mV.
So opamp (LF347) is bad or something in the signal path, but i’m going to check the signal path first.
Voltage at pin 8 of U15 is 1,32V, but after R333 it’s 680mV. So I suspect that C333 has became a resistor, and expanded the voltage divider.
After removing C333 the voltage level is good, so that was a good guess.
After replacing it the voltage level is still as it should be, so problem solved.
