I was using my SR-955HP and it just went almost dead. I tested Q25, 45, 46 & 47 and they tested good with a cheap Chinese tester.
Since I had the desoldering I just replaced them all with IRF520’s.
I’m seeing the following voltages on them. Any help would be apreciatted.
Q25. G. D. S
RX. 0. 4.9v 0
TX 0. 4.8v. .4mV
Q47. G. D. S
RX. 0. 4.9V. 0
TX. 3.8V. 4.8V. .4mV
Q45. G. D. S
RX. 0. 0. 0
TX. 4V. -178mV .07mV
Q46. G. D. S
RX. 0. 0. 0
TX. 4V. -178mV. 0
Q49. B. C. E
RX. 0. 0. 0
TX. 1.2V. 8V. .6V
