Definitely agree. But if the owner wants it gone through by Splawn himself to make sure it’s in tip top shape - likely a better decision over a local tech - then that’s for the owner to decide right?
Denials can happen and there’s always arguments for them - sometimes timing wise if he’s backed up - but supporting your designs should be expected.
And yes I still stand by the fact that troubleshooting is not a skill easily to master. It can be a deep rabbit hole with ground loops, broken wires, intermittent issues, etc. If you’re not experienced at it regularly it can and will take away significant time from building new designs, especially as amplifiers get increasingly more complex.
