Jvc rx-807v receiver manual

You can have a look at the schematic here. I took some voltage measurements of IC which is a dual op-amp: Before the left channel starts clipping, pins 2 and 3 are about 2.

Pin 1, the output, is at 3. When the clipping happens, pins 2 and 3 are about 6. The working channel has its own interesting measurements. Pins 5 and 6 are about The input to both channels is clean at IC even when the output is distorted. I want to replace IC but before I do, I'd like to know. The source? I would think that since this is a stereo receiver that there would be some symmetry to the opposite inverting input, pin 2, of IC but instead pin 2 is wired back to the drain of Q through an RC network.

I believe there is an error in the schematic that shows C connected to pin 6 of IC rather than pin 7. Thanks for your replies. I think you should resolder the board. When shit like this happens in one channel and then the other independently it is almost not going to be the power supply, which is usually the first logical guess.

I am so disgusted with lead free solder that I quit. Think about that. I almost refuse to work on anything with it. It is too unpredictable and also it has corrosion issues you cannot see.

But look for the connections that might be possible for the problem, do not do all the connections. In fact if you have a floating iron you can do it while it is running and find the bad ones more easily. However, do not expect simple resoldering to fix it. If you do not want a recall that is. Isolate the problem first. Does the distortion change with a change in volume?

I would guess that there is a transistor in the front end that is starting to fail because of heat. It doesn't take much. You have an advantage here, one channel works as expected. Take some voltage measurements and compare left to right channels. Use a scope and see where the distortion starts. IC might be a suspect. Follow the audio signal in both channels. Let us know how you make out. Bruce Esquibel. Amazing receiver must say, might start using it with my polk SDA2's if my yammie a dies honestly.

Right now i have it pushing a set of Infinity RS3's as well in my dorm at school. Honestly the is probably pushing more then watts mine pushs watts same THD and what not to give you a idea.

I found my info at a sale post to tho ahaha does anyone know what CSRP is? Does your receiver have it to? I'm a little late to this party. But I got the set up. There's not much info on the web about this receiver or the series.

My ownership experience with it and compared to other similar receiver brands, this one sounds the most clear and clean. I have only used it for music and not video, so far. I've owned it for almost a year.
