We have the UK version JVC MXJ30 Compact Component system. Never had the remote, so manual only Volume. Ours has problem of volume increasing BUT you can reduce with VERY careful adjustment of Vol control. Thought at first it's the (digi?) pot. Tried strip down and it's a major job to get at control.
No schematic yet so in the dark.

Here is a free download manual:

I've a shot of the Vol Control JS971 which must be digital as it connects straight to Micom IC804.
