I read the similar previous post. All caps are properly oriented.
Everything measures as it should until the last step when I put SC25 into place. U4 gets very hot almost immediately. nothing happens to adjacent caps. Measurement between pins 4 and 6 of op amp show 9.46v regardless of changes done to R16. have inspected work and reflowed all solder joints with no changes.
thanks,
josh
btw other preamps work very well and sound great.

Sounds like a bad op-amp. E-mail the details to support@seventhcircleaudio.com.
