Hello All,
I recently started rebuilding the amp section of my creek destiny using IRL2910 as replacements for the no longer available HUF76639 MOSFETS.
I'm trying to understand how VR2 and VR1 play into achieving Vgs threshold on the MOSFETs. If I'm understanding things correctly. I have the right channel working but I don't remember if I turned VR102 CW or CCW to slowly raise the idle voltage (across JP104) from .25mV to 1mV. (Thank you Mooly for that information in another creek destiny post). Does this happen when Vgs threshold is achieved at 1 volt? Which in turn enables VR101 to adjust the idle voltage to the desired 21.5mV? I am afraid of damaging components on the left channel if I turn VR2 in the wrong direction in the event VR1 won't adjust the idle voltage above .25mV. Is it CW or CCW?
Thanks for any help.
Best,
Gregory
