In my case, it's not just futile, it's wrong! I messed up and put the wrong resistors in two places.
There are 2.49K and 249K resistors in the build: the 249K's are supposed to go between 9U and 10U - I put the 2.49K here.
And the 2.49K are supposed to go into R3 on the B side of the printed circuit board. I put the 249K here.
When I energized the amp to set the bias, all 4 leds lit up, then there was a small "tink" noise and the B side leds went out.
So I know where I messed up but I don't know what I messed up. I need to order new parts so should I just get 2 new sets of boards and 2 resistors?
Otherwise the build is going well. Excellent choices on the parts and finishes, it looks really nice.
Thanks in advance.
