dead

Howdy folks! I just received delivery on a Carver HR-722 I grabbed off the bay on the cheap. Cosmetically its pristine but unfortunately its DOA. Im trying my darnedest to locate a legible service manual for this thing . All I can find is grainy blurry crap service manuals. I even looked on Sams...

I've been working through a Pioneer LX-420A valve receiver. I've replaced the electrolytic capacitors and got the FM MPX working again along with the amplifier circuits. But I've got a problem with the AM tuner. It looks like when you switch over from FM to AM, the FM front end is switched out...

I will begin by saying I shorted something in the board myself as I was trying to find a way to cool down the D880 transistor. Let me explain: the tuner was working prior to this. The only issue with it was that it would run for an hour or so until the d880 transistor would get really hot...

The title indicates the problem but I don't know where to go with it. I purchased the iNova and a Peachtree 220 power amp from the same seller a few months back. I was using the iNova as a pre with the 220 and it worked and sounded fine with one exception, I would receive an occasional...

THE INCIDENT I was listening to XM Radio over the AUX input when I heard the audio fluctuate. I thought maybe there had been a power spike (despite being plugged into a surge protector). Suddenly the right channel became very weak and garbled. Occasionally it would break back through to full...

Has anyone had any Onkyo receivers fail after being repaired? I have a TX-NR616 that failed. These models are apparently notorious for the HDMI board dying which takes out all channels. Onkyo was very accommodating and paid for the service and shipping both ways. No complaints about the service...

So, I have these 2 nice RANE ME 30 Graphic Equalizers that we no longer used in a Theatre and neither of them are passing any Audio! Both pass audio only in Bypass mode. All LED's and buttons on the right side seem to work. One of them has an overload light permanently on. Otherwise their...

Hi guys, I've spent considerable time so far trying to work out this problem before posting here. Using an oscilloscope I've traced the signal loss through to the MFC PC Board on the amp. When tracing the signal off this board there is a right signal but no left signal. Numbers 21, 22, 23 and...

First of all I can't find a repair / service manual anywhere for this thing. But it's similar to a beaten and broken LAB-450 parts unit I have, so I can scavenge parts from that if I have to, I think. The problem is that it's totally dead. Looking at the power source, I'm getting a good...

Recently I have acquired a Marantz 2010 in decent cosmetic condition. It was known when I purchased it that it would not power on. I put it on a DBT and I get no light at all. Do I need a less wattage bulb, it currently is a 75Watt incandescent. I have used the DBT successfully testing my...

Howdy Folks! In another thread I bought some Infinity Monitor Jrs from a thrift store for $12. Yada yada yada... Here is the dead Infinity Braun Dome Midrange. No capicitance? From the terminals. When I put the MM to 200k and short the leads I get a 0 as I should. There are no obvious signs...

I just recently picked up a Sony STR 7065A in immaculate condition. I was testing it at the sellers house and proceeded to flip the power switch. I noticed, what I describe as a glitchy start up - with the lamps flickering, fading in and out ever so slightly while the signal to the speakers was...
