Neumann NG

(1/1)

Hello everybody!

I have this kind of dilemma that my power transformer is broken and I have as a spare part BV 47-20-A which I thought to use. Original power transformer for NG was BV3 in my understandings. So my question is, what are the secondary measurements of the original one, meaning Volts and Ampere?I Need to get that 105V for my U47.
BV 47-20-A Has DC measurements 210V and 10ma.
Thanks in advance.

Regards,
Niko Maaninka

klaus:
For powering the U47, you draw only one voltage (105VDC) from the power supply, and with a minimum output current of 40mA, so the spare transformer you found will not work.


Contact Dennis Maximova at AMI-Funkenwerk in Washington state, and have him make you the correct type.
