Pionner SX-D7000 Bias & DC offset Voltage adjustments and specs
Hello Fellow HiFi Engine Folks,
Does anyone out there have experience in setting the amp bias and dc voltages on Pioneer's SX-D7000 receiver? I downloaded the service manual for it's sister receiver the D5000 and compared the schematic with the main driver board on my D7000 and they look similar but the voltage test point pin out numbers don't seem to be the same.
The instructions and voltage specs for these adjustments seem vary vague and left up to the interpretation on the service tech.
Now since I've never worked on this particular model of receiver before my observations may be out in left field and I'm probably missing something.
Also would like advice on proper voltage/wattage lamps for the bass/treble slider pilot lights. I have new 8V/35ma replacements and measured 8.56 VDC on the leads, so these should be okay all-be-it they may burn a little brighter and not last as long due to the higher than rated voltage? Thinking about adding a small droping resister in series with the hot lead?
Any help or comments would be appreciated.
