Everything is flush to the board, the mica caps do stick up maybe 1-2mm since that was as far as I could get them. Voltage into pins 4 and 8 match up.   As for the other resistors, I actually edited my last post with those readings.

So I finally had some time to mess about with this. I tested these 4 resistors and they're all spot on. Tested with a Fluke 87V    R6 - 1.499k R9 - 10.2 R17 - 1.499k R21 - 10.2   I reflowed the OPA 2836 for sanity's sake even though the joints looked nice. I looked over the rest of the...

Hi, I recently built my pupDAC and it's great. I have one issue though, the voltage offset between channels is too much, and one channel is noticeably louder than the other. All of the voltage test points are within .05 volts of stated value, except for the 4.5v one that reads 4.749v. The big...
