Moreplay upgrade discrepancy [resolved]

[dyrstr8s]

I'm conducting the low voltage test with the pc board done, mounted and H1, H2, and AC connected.
On A2, A7 I'm reading 6.3v but on B2, B7 I'm reading 11v.
Seems like it must be something specific to the B socket circuit, but I'm not quite sure what to check or how.
Thanks for any guidance!

You will want to work backwards to where the 1085 regulator is on the upgrade board, then check that the 499 ohm and 124 ohm resistors are correct on that section of the board and that all the solder joints are well flowed out. It will either be a faulty solder joint or potentially one of those resistors isn't the correct part. (Feel free to post photos if you need another set of eyeballs on it)

Will do, thanks Paul!

That was it. Just needed to flow a bit more solder to one of the 499 ohm resister connections. TY!
