Hi Guys, I am now working on an SX-880. First thing, the protection relay won't engage. I pulled out the manual and started following the DC offset and Bias adjustments on Page 17, and found that I have 40 volts potential at pins 5 and 12. Not good obviously. I've been having some really good luck restoring these Pioneers thus far, but I'm admittedly still a newbie, and this is the first one that I've had with this type of problem. I've seen posts before where it's recommended to replace all transistors in the power amp chain when one or more has been blown. I've not gone to check the transistors, but with 40 volts at pins 5 and 12, I'm guess that's probably the situation. Am I wrong to think that? If that's probably right, is it right to replace the whole kit-n-kaboodle, or should I pull each one, test it, and replace the bad ones?
