Adding an external audio input to this excellent boombox
The JVC RC-X610 boombox, like a lot of JVC audio equipment, is surprisingly good but it lacks an external audio input.
Even for an experienced electronic engineer the PCB's are undecipherable without a service manual and schematic.
I have found an very expensive copy of the service manual on eBay. Where do these sellers find their manuals I wonder?
Can anybody point me to a repository of JVC service manuals or specifically, one for the JVC RC-X610 ?
