Thanks a lot for your report which verified what I have been told (gain 11x would be required) for single-ended.
10-2 o'clock would be prefect position.

Ok, so 11 is unitless ratio. That would be about 20dB gain. And this would be a lot more than HP100's 11dB gain. I cannot use more than 11 o'clock on HP (probably >80dB) and yet Fishski13 need 10-2 o'clock. So I guess the low voltage out of gamma2 and high voltage of my source may be the reason.
