Pioneer SX-3900
Rectifier Assy. AWR-211
Power Amp Assy. AWR-097
I never see the 60 volts supplied from the Main Transformer and rectified on the Rectifier Assembly Board dissipate after turning unit off. Never diminishes.
The very large ( 15000 uF ) filter electrolytic capacitors C3 and C4 never let go of their charge on this supply voltage.
I do not understand what circuitry / component (s) are responsible for bleeding this voltage once the unit is powered off.
My unit never bleeds this voltage down ( ???)
Any suggestions.
