Also, I scoped the PS voltages.

Is 0.5v noise excessive? Shown is 5v supply measured at test pin on PS pcb.

I'd get friendly with some Pioneer tech support types and secure
a schematic.

Others have similar noise except 139v: 12v (0.5v noise), 60v (0.5v noise),
139v (5.0v noise) 170v (0.5v noise).
