Elissa Posted September 6, 2010 Report Share Posted September 6, 2010 My Fisher tube amp is on the mend so I've a Yamaha digi receiver that I've been using, though now it also seems to have taken leave of its functionality. I turn it on and after 6 or 7 second it switches off. What to do? I thank you. Quote Link to comment Share on other sites More sharing options...

papsrus Posted September 6, 2010 Report Share Posted September 6, 2010 I would but I'm have people over for dinner. Thanks though S'OK. Wish I had some better advice, but sadly .... If it were me, I'd assume there was an overload or short somewhere, in which case I would probably leave it off. Quote Link to comment Share on other sites More sharing options...
Spontooneous Posted September 6, 2010 Report Share Posted September 6, 2010 I'd guess that the power supply, the part that converts the juice from your wall outlet to smaller amounts that the sensitive electronics can tolerate, has gone bad. And now, every time you turn the receiver on, the electronics might be getting pounded with voltages that could be ruinous. Yes, unplug it.

Elissa Posted September 7, 2010 Author Report Share Posted September 7, 2010 Plugged in a different receiver the same strip and it works ok, though only w one set of speakers. Can't say much for the sound. Alas, fix the Fisher or scrap it all and start fresh. Quote Link to comment Share on other sites More sharing options...
AllenLowe Posted September 7, 2010 Report Share Posted September 7, 2010 some possible courses of action: throw it out the window? leave it on the subway tracks? drop it from the Manhattan Bridge? send it to Mayor Bloomberg? put in the oven at 425 for 15 minutes. Marinate and serve. Quote Link to comment Share on other sites More sharing options...
Kevin Bresnahan Posted September 7, 2010 Report Share Posted September 7, 2010 Many years ago, a co-worker of mine had this same problem and I had him check his speaker wires. I told him that it sounded like one of his speaker wires had one strand that didn't get onto the terminal and that tiny wire was probably touching the other terminal. He went home and checked his speakers and found one stray wire jumping across to the other terminal. I felt like an audio god. BTW, if this is what you find, it might be what killed your first amp. When people swap an amp, they rarely check the speaker wires at the speaker. Also, you can measure the resistance of you speakers. A blown tweeter can be shorted. If you do measure the speaker resistance make sure to remember that it isn't 8 Ohms. 8 Ohms is the impedance. You're just looking for a short or very high resistance.

Elissa Posted September 7, 2010 Author Report Share Posted September 7, 2010 Kevin: You Audio God! Thanks so much. I'm at work now but will hook it all back up soon as I'm home. I think you have something there. My speakers are a little odd in that some dudes on Long Island hand made them for me with really long wires as I had a huge pad at the time, and an audiophile friend who sent me out there to get them, but the wires are a thousand little copper wires per + and -, left and right, and fairly frayed. In fact the amp suggested to me that it was something with the speaker wires, but I didn't believe it at the time. Maybe I'll snip off a bit at each end and see if that doesn't help. I thank you. Where as YOU Allen Lowe: just you wait til I'm at the helm of a video camera with YOU as my subject. Muahahaha Quote Link to comment Share on other sites More sharing options...
PHILLYQ Posted September 8, 2010 Report Share Posted September 8, 2010 Elissa, Kevin may have the answer, as I blew out one side of a receiver the exact same way, wires to the speakers touching each other and no left channel. Quote Link to comment Share on other sites More sharing options...

Elissa Posted September 13, 2010 Author Report Share Posted September 13, 2010 Kevin, I snipped off a bit of the speaker wires and put it all back together and it's working beautifully. Thanks again. Quote Link to comment Share on other sites More sharing options...
