Professionally
serviced Pioneer SA-6500 2-channel integrated stereo amplifier.
Completely refurbished, capacitors upgraded, case refinished, all functions tested and
passed. Expected to reliably meet or exceed original spec.
Notes from the technician - Initial assessment: -intermittent output -several cracked solder joints on amp board and power supply -failed power indicator bulb
Service: -Resoldered 10-15 suspect solder joints (input jacks, grounds, regulators) -inspect amp board for burning or corrosion: good -junction tested all amp board transistors and bias diodes: good -checked all P.S voltages -completely recapped (all electrolytic) on main PCB with all nichicon low esr -cleaned all controls and switches with Deoxit, and finished by applying R100 to prevent future oxidation -replaced blown indicator bulb with wired LED -this unit does not have trimmers for dc offset or bias: checked emitter resistor drops, and differential front end transistors -final bench test 2 hours
