Onkyo receiver/amplifier

Re: Onkyo receiver/amplifier

I got the spec from Steve and in the schematic L109 says 102j. 102j is 1 mH with 5%. Are you sure about the 183 markings? Maybe the schematic is out of date?
Also, I'm thinking the inductor is also used for the pilot tone detection as well as removal and makes the stereo detection not work since the inductor is shorted.

See, you have the inductor in hand. What is written in it? I think (from your pic) that is 183...

About the inductor less making the stereo decoding inoperative, is not possible, it should work.

Re: Onkyo receiver/amplifier

The schematic has it as a 102j which I don't know if is 1000uh? .

Hi Steve

The 102j is the capacitor C175 in parallel with the inductor, 1nF ( 1000 pF )...

Re: Onkyo receiver/amplifier

You are correct. I just looked again at the L110 and C176. At that section , they are seperated better and can see that 102j is for the cap value. I saw the 183 on the inductor in the pic, but I read the 102j at the lower location which is squeezed. Should have put my magnifier visor on. haha. I had it blown up to 400%. The old eyes aren't what they used to be. Good catch.

I know, my friend. I'm 57 and only with reading glasses and almost sniffing the schematics, I can (or i think i can... )...

Re: Onkyo receiver/amplifier

ok I think I understand now, and the K signifies 10%. I found something in Mouser that kind of looks like the same piece but slightly bigger. Would this do?

I would buy two, for perfect left right simetry...

Re: Onkyo receiver/amplifier

Thanks Tube_Dude, I ordered them. Just curious, but is there any harm in leaving it shorted for now? Is there a degradation in sound quality, etc?

No harm. Just some brighter sound, till you put again the coils in circuit. But you can hear the news in the radio and some music without any fear.

Well, in second thought, sometimes the news are really frightening...

Re: Onkyo receiver/amplifier

Forgot to ask about the maximum DC current. Do I need to worry about that parameter. The part I picked has a max. of 35 mAmps. Is this a typical value for this application?

Re: Onkyo receiver/amplifier

Thanks everyone! especially Steve2 and Tudedude for the schematic and identifying the right part and function. I got the components today. They were a little bigger in size to the broken one but the lead spacing was the same. Removed the wire, and the other coil, popped these in, and the sound is great!! The stereo was always working as Tudedude had explained indirectly. It was an operator error in pressing the FM Mute Mono button. Looking forward to my next challenge
