If this problem with trimpots is common (same type), maybe you also have them starting to quit.
This is a bad design (shame on Pioneer engineers).
The diodes need to be three and the trimpot needs to be in paralel with one of them, then open pot does not then result in fully closed output transistors. There are other ways too.
