    Headshell/tonearm hum due to dirty or loose connection?

    I've recently run into a background hum problem with my Thorens TD 145 (TP-16 tonearm/Ortofon Super OM 20 cart). After removing the headshell to invert the deck and adjust the suspension, I now have a background hum that gets worse (or at least different) when you touch the tonearm and...

    ELAC Miracord 50 HII hum

    I picked up this TT at an estate sale. In great condition but when I connect it all up, there's an enormous 60 hz hum that completely overpowers the signal. Internal grounds are connected and I even installed a ground wire from that common point to my amp's ground point. The TT has a DIN...

    KR-7400 with a constant hum in both channels

    I picked this up recently. Has a hum in both channels. While troubleshooting I found that if I tapped the relay the hum would go away for a few seconds. So I reflowed the relay. No change. Ordered a new relay, put him in. Still has a hum, but tapping the relay now has no effect. Any ideas...

    Technics F-G-Servo Player SL-23 Humming Issue

    Hello, I bought a Technics SL-23 turntable, and it played fine when the guy connected it at the store. I took it home and then found out that the needle was damaged, probably my fault, so I bought a new one and replaced the broken one. I have power speakers, which worked fine with my previous...

    Marantz 1060B Rebuild & Troubleshooting

    Almost since the beginning of my time on this forum I've heard derogatory comments about the 1060B amplifier. Build quality is terrible, sound is terrible, nothing like the original 1060, etc. So of course I had to find out for myself. :D This one came to me in great cosmetic shape and...

When I startup it will produce a short hum like sound in both speakers even at minimal volume level. The...

    I noticed today that if I crank up the volume during playback on my TT I get a very low frequency hum through the speakers, almost inaudible but I can see the woofer moving like crazy. It only happens while the needle is touching the record. Is it some kind of feedback? Or some other kind of...
