Dear all,
I started with the U47 featuring the spirit tube from phaedrus audio and using their circuit.
But I have difficulties with the circuit, which might explain, why my construction does not work.
There is no voltage anywhere in my circuit.
Attached you will find the schematic with the two areas I can't get my mind around.
1.
The resistor with the "NF". I thought this would mean "non fitted" and should be left out. so there is no connection between the 100M resistor and the ground.
2.
The marked connection from the transformer on the XLR-side. This looks like the "2" and the "3" from XLR go into the transformer and from there out of the transformer giving 45 V to the circuit.
I have a FAB V8 which has the two ins and two outs and two brown cables for ground. I can't see how I can get the marked lead out of it.
Thank you all and best regards
Simon
