| Tracking down a hum. Story has a happy ending. Since the source of the hum has been found and dealt with It was the power outlet I was using odd in that it didn't affect anything else in the system Combined with the new parts installed by Rogue. This almost 20 year ol... | |
| Tracking down a hum. Well I plugged everything into a different outlet. So far so good. I'll have to give it some time to see if that really was the problem. As whart said. "It's usually something stupid." It appears jond was right as well. | |
| Tracking down a hum. Well today I swapped emails with the people at Rogue. They found a faulty SW 5 switch. This is in addition to replacing 5 capacitors earlier. I need to get a new battery for my multi meter, and a set of precision screwdrivers so I can get at the b... | |
| Tracking down a hum. A bad solder joint would not surprise me. I bought this thing used and it had a bad solder joint in the left channel variable output. Got that fixed no problem.Hopefully they'll get it fixed. If they don't I'm going back to a solid state integrate... | |
| Tracking down a hum. Oh yeah I sent it back to Rogue this morning. Power supply and all. There isn’t much in the external power supply, a transformer, some wires and a fuse. I don’t remember much else. Hum is present in both channels and pulses. Failing rectifier mayb... | |
| Tracking down a hum. @ jond I don't think its the line. I swapped out the amp with an old NAD C 340 using the preamp outputs and everything is fine, nice and quiet. No noise in any other components using the same outlet. | |
| Tracking down a hum. Well after listening for a couple of hours out of nowhere the noise is back.Evidently the folks at Rogue missed something. This time the noise doesn't dissipate. The noise pulses. get louder then softer louder then softer. I have no idea what the ... | |
| Tracking down a hum. Okay I got the amp back today. I was hoping for an itemized list of parts replaced. I didn't get one. It looks like the replaced all the capacitors in the board nearest the transformer, and one resistor was replaced. I'm listening now and so far s... | |
| Tracking down a hum. @noroamnce, kudos. I'll know more about which caps were replaced when I see the invoice on delivery. @thecarpathian. The explanation given to me is they were unable to get schematics with values and were reluctant to work on it as such. Rogue woul... | |
| Tracking down a hum. @noromance and others. I got a call from Rogue today. It's repaired. They replaced 6 components. A bunch of capacitors in the power supply and a resistor in the voltage regulator. Cost $255.00 all told. Disaster has been averted no explosions. | |
| Tracking down a hum. Sending it to Rogue. I'll post here what they tell me the issue is. | |
| Tracking down a hum. Well after the weekend the noise is back. It's through the speakers and independent of the volume control. It goes back to Rogue this week with my contact information and a description of the problem. | |
| Tracking down a hum. Mine is a line stage. Look for a small orange and white switch it's upright and small, near the transformer. I was able to find it without too much trouble | |
| Tracking down a hum. Post Script to all this. I took the amp to a shop for repairs. The techs (2 of them both experienced) could not find an issue. Told me everything in the amp is "up to spec". Gave it back to me no charge. Get it home hook it up and the hum is still... | |
| Speakers 10 years old or older that can compete with todays best, Two models I don't see mentioned are The ESS AMT series (1A, B,C,D) and the Rogers Studio Ones. Completely different designs that both produce outstanding sound. I'm especially fond of the ESS. A friend of mine still has his from the mid 1970s. He... |
