Here are some recent Design Ideas which may be of interest to our readers:

"Use a Boost Regulator beyond its rated voltage" shows an 11-14V input to 48V 100 mA output.
Might be useful for phantom if it could be made quiet.

"Measure an amplifier's THD without external filters" is another null test circuit.
It's good that we keep re-visiting this topic.

"Use a photoelectric-FET optocoupler as a linear voltage-controlled potentiometer."
Control linearization technique using a second opto-FET.

"Save 3 dB of output power using feedback to set the output impedance."
ricardo may have an interest in this one.
