Instrumentation that requires an ultra low noise source can be made from
tube amp. Some transistor amps will also work. Both are run in an ultra linear mode. Both require filtering know how. The mosfet Switch mode are plentiful and efficient but are noise ridden. The noise is spurious.

A video of tube amplifier putting out 24V can power 19.5 watts.
