New to site..first post..bear with me.
Ok, so a good friend of mine upgraded his receiver so I upgraded my NAD to a Pioneer SX-780. Now this is probably my best friend, and for him money is not an issue, and he's one of those guys with probably $8K invested in his audio set up, with about 4,000 records. So he's serious and he knows how to clean up and repair vintage receivers.. this was 1 of 3 he SX-780's he had owned. Before I got it from him (not shipped, I picked it up), he says that he: Cleaned all switches and pots with contact cleaner, replaced lighting (I think he put in amber LED's..not sure if that could have any bearing on this issue but just in case), he striped the wood cabinet and sanded and re-stained, replaced some knobs, and tested it before he sent it. One important thing to note is that he tested it with an external pre-amp. Said it worked fine.
Now I get it, I'm stoked for the change although honestly I love my NAD. I plug it in, connect my table straight into the phono input. I turn the knob to phono, and set a record to play. So I heard nothing but a slight buz (I just hadn't grounded it yet..got in a hurry to see it work). So I notice the buzz and ground the record player. The buzz goes away. No sound.. then I keep turning the volume up and I notice at about 75% I start hearing the sound of my record. Very vauge and low..barely audible. So I think..huh lets try speaker input B.. did that, same thing. Same for AM and FM, hardly audible at 75% volume.
So I instantly think..the pre amp isn't working. So what I do is I go ahead and use my external pre-amp and go that way, into the phono.. nothing. Now I have no sound whatsoever.
Then, thinking well what If I go from record player to external pre amp, to TAPE IN. At first it doesn't work, then, I flip up the Tape Recorder knob on, and it works.. sounds GREAT. Then I listen for a bit, play with some of the bass and treble, just seeing what kind of range I was getting. Then I turn it all OFF.
Turn it on again.. nothing works. Its getting power, the lights are on. No sound. I realize..what input did I have it on when it was working..AM,FM,Phono,AUX.. cant remember. I still hear the low sound of the am and FM, but nothing from the record player.
I'm checking fuses tomorrow, in the event that me turning the volume up that much blew a fuse, or some internal mech flipped a switch in some kind of protective maneuver.
How should I go about this? What steps should I take after checking the fuse?
Thanks in advance!!
