Is a direct coupled connection possible from front end mic head amp and power amplifier?


For example:


Can the low voltage anode (of the order of 3 volts) of the EF183 on Pleiades microphone preamplifiers be directly connected to the base of a 2N3053 Pleiades power amp driving the high Z PHIlIPS AD5046N (800Ω) or Sennheiser HD580 (300Ω for each moving coil).


So that no capacitor is needed between the two.


The response should be down to the limit of 0Hz.


The only transformer can be the microphone input transformer.
