The depends at what level you need your lowest threshold to be. I think the best solution would be not to connect the 100k resistors to ground but to a small positive voltage. For example put 10k resistor and schottky diode from +15V to ground and this will give you a 0.2V - 0.4V voltage where to connect the 100k resistors.thank you Heikki
how much extra Gain is needed for bjt to start working in a proper manner?
best
Can someone please tell me if 42tm019 can replace Hammond 107N?
Looking for cheap easy solution
