Electro-Voice 635A with Canford input transformer and Pleiades V4 at 3.6V

Amazingly nice combination.


The Canford low to high impedance converter has an inductance at the primary of about 413mH.


The 635a sounds less bass heavy than the MD21 or D130. 


And the Pleiades V4 has an input impedance of about 100KΩ.


So the spectrum balance to listener's brain turns out fine.


The V4 EF183 electron tube pre preamplifier booster was powered by just 3 AAA batteries, that is by just 3.6V. Anode voltage was even less due to the voltage drop by the anode resistor.


It is amazing how low noise it sounds. Before connecting the microphone one might doubt it is operating at all.


And when this excellent microphone is connected, one can hear every detail in the ambience too.


Setup:


Vintage Electro-Voice 635a - Canford adapter with Neutrik? input transformer inside Neutrik modules - Pleiades V4 - Realistic 32-1101A - Sennheiser HD 580
