Thanks. 120mA is about right. And you get from 100mA to 120mA with just one turn on the pot??
In any case, if the amp sounds clean to you it's probably ok.
To check the CCSs look at the voltage across P2. It should be constant when signal is applied. If it shows significant variation the CCS is not working and either Q7 or Q8 or both are bad.
