Thanks for clearing that up. I was running the amp at around 250mv that's why it didn't sound right. Every thing else checks out in the troubleshooting guide. Also I had the power supply set at 24v not 29v.
S1+ to S1- 23.08v
DC offset input to output gnd .02v
V+ to V- = 21.8v on L R and gnd
V+ to input gnd = 10.8v
V- to input gnd = 10.9v
Amp is drawing 100 - 125ma depending on opamp 8610, 637 627
Dc offset R output to out gnd .2 mv Left .9mv.
