Hi,
I haven't used my gssl for 2 years and yesterday after hooking it up in the studio it gave me a lot of hum added to the music. The hum also effects the metering, but the music also. All options seem to have some effect on the signal.
Now i measured the voltages on main board and it is not the +15 and -15 on all NE5532 IC's. The test tracks do measure good voltages. At the input stages it is down to -13.2 and + 15.3, same as the VCA circuits. at the output stage there are good values.
Without a scope, where and what would cause this problem?
I build it 12 years ago, could the capacitators already be bad ?
