PPI PC 1400
Im get 38 volts on the outputs of this amp..
I messed with the dc offset pots but it makes no difference .. I also measured the resistance from the driverboard transistors to the legs as i did in a previous repair on a PPI PC21400 im getting 100 ohms from point a to point a and point b to point b.. All outputs are measuring good.. Any ideas on where to look next since i still have 38 volts on the output? |

Do you have both positive AND negative supply voltage on the...
Driver board? Op-amps? Outputs?
