I measured the DC voltage at R15, and R32 as being 21.6 and 21.8. I was very careful to get the polarity right and have checked again. Also checked continuity between the pins of U1 and U2. All diodes have the band that matches the silk screen.
Is there an issue that would cause it to be 21.6/21.8 volts instead of the +/- 24 volts?
What jumper settings should I have when I measure R15/32?
