    Thumping / Beating Noise From Speakers During Playing

    I have a great pair of Boston A100 and A150, recently though I noticed when I started up the A100s there seems to be this almost thumping or "door knocking" sound, especially prominent near the end of the record. It's very hard to describe, it's a soft thumping sound with maybe one second...

    Marantz 2220: Need help troubleshooting hiss

    I have been working on restoring a Marantz 2220. AK link to restore. Overall it sounds pretty good. I notice that there is more hiss (than my other Marantz units) when the volume is all the way down. It does not matter which input selection it is on (AM/FM/PHONO/AUX) the hiss is there at 0...

    hissing/white noise from one channel, luxman r600

    Picked up a luxman r600 a few days ago that had a burnt fuse, replaced that and got it up and running. Everything works fine with it except that the left channel hisses. It's not very noticable when there is something playing, but it's there constantly. The hissing gets louder as I turn up the...

    Rectifier noise in outputs.

    I have an SA-5300 that I've been recapping etc. Just sat down to try it out and it quite honestly blew me away! Sounds really good. Very clear sharp sound stage and deep natural bass.... Only one small problem remains... when there is no sound, I can hear the "pulses" of the rectifier diodes...

    Humming Carver PM-1.5

    In order to properly feed a pair of JBL's Ti-3000 I recently traded, I purchased the aforementioned Carver power amp only to find out two strange behaviors: A) buzzing speakers - the speakers have a permanent buzzing sound that increases when both/either left and right gain controls of the amp...

    sansui 881 background noise - cyclical ticking sound

    so I have a Sansui 881. I decided to recap it earlier this summer and it had been working fine. Over the weekend, I sat down near my speakers while no music was playing and started hearing a persistent ticking/flapping sound. It's not a hum but a cyclical ticking sound. If I had to guess...

    Marantz 2238 - Phono stage issues

    I just bought a 2238 receiver. Didn't have a chance to test phono input before buying, only FM and Aux. Tested phono at home and noticed that left channel volume is MUCH lower than right channel. Made a series of tests to try to pinpoint root cause. Results below: 1. Both channels have a low...

    sx-838 background hiss, should I just deal with it, or possible to troubleshoot?

    Hello Everyone, Back again with some follow up questions on my Sx-838. It seems as the big jobs(replacing caps and transistors on control board and power supply) get done I find little things to nitpick about! I am saving up for a tuner alignment, but in the meantime I as using my sx-838 as a...

    2SA750 -> ZTX795A = hum? (Rotel RX-803 phono)

    My Rotel RX-803 had a noisy phono section, so I though I'd try swapping out some transistors, starting with the PNP input pairs. I replaced the original 2SA750's with Zetex ZTX795A's. Now I've got serious 60hz hum. I've double checked the pinout: 750's are ECB, 795's are EBC, but I've got the...

    Output from computer produces noise on Akai AM-2350

    Well I've been fighting with an issue with my computer to amp sound output. In a previous thread I started (link at the bottom, thanks @Oldsansui441 ) I indicated that there was a noise/humming in my Akai amp, discovering that it would sort of go away after pressing the bass knob. I did the...

    Akai am-2200 recurring nightmare!

    I've had this unit for some year now and only recently a (quite slow) technician was able to fix it up; previously I would get it back from him and after a while turned on it would start with crackling noises. Worked ok for some two weeks.. And now it's back to that problem.. And after testing...

    Akai AM-2350 noise in the bass knob

    Hi guys, my beloved AM-2350 black amp is acting up since a few months. Used to make a kind of soft hiss sound after a while when I turned it on, so I took off the cover and used contactmatic (the closest thing to deoxit down here) and then it seemed to improve. But the noise was still there...

    Occassional LOUD cracking and poppin in HK 430 Twin Power

    Got this gem from a coworker. Sounded like lightning in a bottle when I powered it up. He said a channel was out 30 years ago when he shelved it. Worked fine for me, except that it had very loud cracking and popping coming from all channels and even at zero volume. So I cleaned it like crazy...

    Help with a Sony STR-GX10ES repair

    I have a Sony STR-GX10ES that I'm trying to revitalize. I loved the sound of the bad boy but it is sounding its age. It is dropping sound in and out. It is not an abrupt "cut in/cut out" but more of a staticy fade in and out. I verified that it is not the speakers and have switched inputs...

    Hum in the grooves

    I recently got a Yamaha GT-750, and have found it to be the quietest turntable I've ever owned. So when tonight, I got out my original pressing of John Coltrane, A Love Supreme on Impulse, which I have always thought to be immaculate, I was surprised to hear a humming when I put the needle down...

    Any Yamaha GT-750 owners out there? Noise problem from platter.

    I posted previously that the noise issue had disappeared but I was wrong. It's still audible. I've cleaned and re-oiled the bearing and run it overnight and it hasn't made any more difference. There seem to be scratch marks on the motor pcb surface right below the outer rim of the sub platter...

    Yamaha GT-750 motor noise

    I just got a GT-750 at a good price - but! When I switch it on there's a noticable scraping noise coming from the platter. It reaches speed ok, the quartz lock indicator comes on and the sound from the jazz album I put on was fantastic. However, a friend of mine who was over, no audiophile but a...

    Used a Spin Clean, record sound worse no matter what

    I used a Spin Clean, and now the vinyl that I cleaned sounds horrible with pops and clicks and best way to describe it, campfire. I tested this vs. records that haven't been cleaned using the Spin Clean, honestly night and day. The records themselves were clean, and I mean NM- to brand new. Yes...
