[TechAssist] Re: JVC stereo model RX-3 need service manual.

Thanks Darryl,
Your right. I have done that before ! Guess I had a "Senior" moment.
I found a pin-out of the STK4181V in an old ECG catalog. It crossed to an
ECG1317.
I'll try scoping the inputs, and outputs, and trace the audio back to it's
source.

Best redards,
