hello friends,
I have a JVC XL-V131 and tried to build a new fetbased output-amp instead of the opamp-section. First attempt was very successful but then I made a fault and killed something. Now there is no more voltage in the dac/output section. I tried to fix it, but I have no schematic for it. Does anybody have a schematic for this player? I can`t find any in the net.

Don't know if you are interested in buying a manual, but looks like somebody has one:

btw this is a low-end player from JVC , i like the XLV164 more, sounds really good , when mod the output;
has MN35500 filter/DAC , thats really not bad; series is about 4 years later (1993 vs. 1989).
so if repair xlv131 is too much problem, take a better xlv164 /174 /184 on ebay, sometimes can get for 10 bucks or so...

I fixed the problem! The two VC45801 Opamps in the output section were the problem. Now the player is working again.
It has a LC7881 dac and I now run the Vout in passive mode. The sound is amazing, deep warm natural and detailed.
But if anyone finds a schematic for this player I would be glad to have it in future!
