Known Microphones the TMPS supplies cannot power:

AKG C60, Sony C37A, Lomo 19A19

A handful of microphones have the output transformer to the audio circuit in the power supply.  These will not work with the TMPS supplies that provide clean regulated power, but do not contain any audio circuitry other than the output connector.  Custom making a supply for these mics would be very cost prohibitive, so we recommend you look for the original.
