Hello!
Recently purchase Siemens Sitral V276a preamp. Heard a lot about it's hight quality sounding.
But as broadcast preamp it's build with build-in HPF and LPF. Same filters in V276a and V276.
I find some sketchy information about how to remove HPF and LPF there:

But not all became clear.
The main idea that for remove LPF it's necessary unwind coil of the drossel D1 (inductor) for up to 100 winds or just connect it to the ground.
But I did not find any reliable information how to remove HPF. Heard that some of caps should be removed...
Any info?
