Re: Onkyo receiver/amplifier

I tried uploading the manual 3 times, but it keeps failing.

there seems to be a filesize bug for .pdf files. the manage attachments thingy says the limit is 9.54MB, but the actual limit is 1.91MB, so any file bigger than that just won't upload.
i've PMed topcat about that a while ago..

Re: Onkyo receiver/amplifier

I tried uploading the manual 3 times, but it keeps failing. L109 (for 120 volt USA and Canada) models Part # NCH-2140 or 231092 (onkyo #). The schematic has it as a 102j which I don't know if is 1000uh? Yes the 102J is 1000uh, 1mh. The J is 5% tolerance.

Measure L110. the value will be the same.

Just to be sure about the problem, short L109, and see if the FM work properly, in both channels.

L109 are just part of the MPX output filter so, shorting it with a wire link doesn't cause any problem.

"L" indicates that it's an inductor/coil..

Re: Onkyo receiver/amplifier

I found something suspicious on the FM/AM daughter card. A component lead was broken. Anyone know what this component is and where I can find a replacement. Could this be the cause?

Re: Onkyo receiver/amplifier

Its a pretty old one. TX sv545. Had it for at least 10 years, and it was a hand me down from my brother in law so he had it for a while. I'll try cleaning to see if that fixes it.

Re: Onkyo receiver/amplifier

but fm is built in, right?

But still could be switched with a mechanical switch, since we don't know the model or how old it is....

I fixed an older Pioneer receiver a while ago where the left channel was dropping out. Was a dirty speaker a/b switch.

Re: Onkyo receiver/amplifier

yes, FM is built in. CD, and the other sources are inputs in the back of the unit

Re: Onkyo receiver/amplifier

Depending on the design, could be as simple as dirty switch contacts.
I'd start by cleaning the switch that selects the input.

I have an old Onkyo receiver/amplifier that has a small problem. When listening to FM, one of the channels (I think it is the right one) is very low. However, when listening to any other source (CD player, Satellite receiver, etc) everything works fine: right channel is as strong as left. Any ideas why this could happen? Could a bad cap cause this?

Thanks for any help
