Hi, so I know very little about repairing gear, but I'm willing to attempt a repair if anyone has an idea what may be a likely culprit for the problem that just manifested.
I have the Yamaha R9, and I had speakers hooked up to A and C speaker inputs. The right output on the B speaker never worked, so I didn't use it. Into the C input I had a Niles Audio SPS4 speaker switch box which had 4 inputs. I had 3 sets of speakers hooked up to that box, and on the 4th input, I went to test an M-Audio DX4 powered speaker, which promptly blew the Yamaha receiver. No power or anything now to the receiver.
Here's what I've done thusfar. I have no speakers or ANYTHING connected to the receiver, just power cord. I only see one fuse, a 250V, 10 amp, which although is a Littelfuse, I replaced with a Buss fastblow 250v 10amp. It blows instantly when powering up. My questions are as follows...
Is there something about the Littelfuse that makes a difference? It looks like ceramic or paper wrapped perhaps (it's white), as opposed to clear glass like the Buss. Is there a difference and do I need the Littelfuse? I can't get it locally but can buy on ebay I suppose. Could it be something as simple as that?
Is there another fuse somewhere that I am missing?
If not, Is there a likely culprit for what caused the issue by hooking up the M-Audio DX4? If it blew the power supply, then I guess it's a cool looking paperweight now. But I'd really like to get it working again. Any ideas?
As I stated, I know little about gear repair, so if please reply if you seriously are interested in helping, as it would be greatly appreciated.
Thanks in advance : )
