This microphone comes completely serviced and modified/upgraded: the noisy internal mains transformer has been removed and a HQ audio transformer was added to provide 200 ohms balanced output signal. Also the tube circuit has been slightly modified for optimal performance and a 3-position ground lift switch was added.
The mic is now completely free from hum and noise.

*** Original Thiele M4s in their original state without modification are virtually unusable due to excessive hum and noise !

The set includes a new custom-made power supply unit (PSU) for tube preamplifier and capsule polarization. All voltages are adjustable and stabilized.
The mains voltage can be set to 115 and 230 VAC.Dimensions PSU: 3.5" by 6.3", 10.23" deep (90 x 160 x 260mm)
  Excellent condition considering the age, the microphone sounds great !
