and if I tell you that I have an old West Germany pres rack that leads inverted polarity on the chassis?
Like all old west german gear...

and... I use it, into a wooden case. If i gets in touch with modern equipment... FLAMES !

But it sounds extraordinary, and I am very careful in studio

RFZ V781, the scheme Rupert Neve copied for his 1081

dated 1978

 

Hello,

this isn´t West Germany Equipment..
There are two V 781 and two W 745 from the Rundfunk- und Fernsehtechnisches Zentralamt der DDR.
This equipment was developed and built in the GDR. The V 781 contains, depending on the version, up to 2 discrete operational amplifiers. Both types of equipment are a part of the System 700 of the RFZ.

The reference point for the power supply is +24 volts. That's not inverse...
Best regards!
