What does a service involve?
When we service an amp we do the following: we clean all the pots, jack sockets, and valve sockets; we check that all the valve sockets are correctly tensioned; we check the valves for microphony; we check the integrity of the safety earth connection; we check that the output valves are correctly biased; we check the state of the electrolytic capacitors and we give the amp a general check for other potential faults such as dry joints. We will also play the amp! We and our colleagues at Angel Music have extensive experience of most classic amplifers, so we can tell if your amp is not sounding right.
