    TD125 SME 3009 Confusion

    Hi everyone, I’m a bit new to this so please bear with me! I’ve just purchased a very nice Thorens TD125 with an SME 3009 tone arm, and am having a bit of confusion on the best way to connect it to my amplifier etc. In short, the previous owner was clearly very knowledgable and had a 3 pin...

    NAD 7020 Distorting - Earthing / Grounding Question

    Hello everyone at AK and thank you all for this great resource (that I often spend many hours studying). Summary: On this unwell 7020 I am seeing 9V DC between power supply filter cap ground and chassis earth/ground. Is this normal? This chassis is earthed to the mains lead and the wiring and...

    Yamaha YP-700 grounding fix (applicable to many other brands too (separate signal ground from chassis/tonearm ground)

    I got my Yamaha YP-700 quite recently and have undertaken a number of maintenance activities. There was a slight noise coming from the turntable. First I thought that maybe the noise was picked up by a fairly long and cheapo RCA-cable from my phono preamp to the speakers but this was not the...

    Yamaha C-65 Preamp Grounding

    Hi all, I picked up a nice M65/C65 stack a month ago. The amp is being worked on, and I've been using the C65 very nicely with my M70. Much of the scratchiness in the tone knobs, input switches, and volume/loudness pot has disappeared with use. But the volume knob's noise has not disappeared...

    Static problems with all my turntables

    Hello! I have an extremely irritating problem when playing my records. After just 1 play the record gets very statically charged. I live in Sweden and it's been raining here constantly for the last few weeks so I doubt it's a humidity problem. I've tried different mats and the only one that...

    CT-F 9191 hum on both channels in play

    Hi guys, it has been quite a while since I posted something here. Now I am stuck fixing the hum in a CT-F 9191. The hum occurs when pressing the play button and is equal on both channels (meters show around -20db). This can be reproduced even without a cassette (relevant switches engaged). It...

    Marantz 1060 grounding

    I am working on a major rebuild/recap of a 1060 and have run into an area I don't recall seeing addressed in the the many past threads/postings on the 1060: grounding. The unit I am rebuilding has clearly been worked on by someone before, so it is not always clear what is original and what is...

    Yamaha C-4 preamp hum.

    This amp appears to be working well in all regards except that there is a significant hum when Phono is selected. The hum also comes through substantially on Aux and Tuner. Hum appears to be stronger through the left channel. Hum is lessened when ’Tone Bypass’ is selected, but...

    Thorens rebuild, ADC tonearm, and audible hum.

    Ok I have a finished Thorens td124 rebuild and upgrades and I put on the ADC LMF2 tonearm with an old Ortofon OM20 and an old GradoZf3. Grado is shot, so toss that. Ortofon gives me one channel only but sound is good. Both carts gave me an audible hum. Ground is attached at the back of the...

    Grounding question for a somewhat convoluted setup

    Hey guys, I have a question about grounding in a setup that I want to use to play 78s. It's kind of convoluted, but I think it will work well once I get the grounding figured out. I don't have much technical knowledge about grounding, but I do want to make sure that I don't damage any of my...

    Grounding TT with no ground post to new phono preamp

    I was recently gifted a Crosley c200 TT which has a built-in phono preamp. I recently decided to upgrade the built-in preamp by switching to a Hagerman Bugle 3. The new phono stage has a grounding post but the TT does not. I am noticing a small hum when I have the TT connected to the phono...

    MA5100 grounding issues???

    I have an MA5100 that is very dear to me. 20 years ago I stumbled on a yard sale. They were using it to play music...... for the yard sale. I asked if they were selling it. They said yes. I asked how much. They said $15. And here we are. I adore it. After two recent back-to-back negative repair...

    Kenwood 700M : common ground?

    Hi folks, I have a Kenwood 700M amplifier and I am not sure if it has a "common ground" or not. I am asking because I also have a Koss ESP-9 electrostatic headphone set that requires tapping into the speaker outputs on the 700M to drive them. I have read (and yet don't fully understand) that...

    Elac Miracord 50H Mark II

    Where is the best place to attach a grounding wire on the Elac Miracord 50H Mark II turntable? Mine has a fairly decent hum that lessens when I touch a grounding wire to it but I can't seem to locate a good permanent place to affix the wire. Thanks.

    2220B adding actual Ground to Power cable

    Hi! New here and thanks for all the info here on my 2220b. I have had this about 10yrs and over the holidays I noticed things didn't sound right and sure enough all my internal voltages were off a little from spec. So got out the meter and spent some time on the bench getting everything back to...

    Buzz sound with Sansui Belt Drive SR 2020 BC

    Hi, I have a Sansui Belt Drive SR 2020 BC turntable that I play onto an amp (Technics SU Z-200). My issue is a buzz sound can often be heard when I play records. I starts when the needle hits the record, not before. I thought I would need to plug in the Ground cable, but the one coming out of...

    2325 hum in both channels

    I have a 2325 with a hum in both channels. It starts 5-10 seconds after the relay engages, unless the receiver is already warm, then it starts sooner. The hum is there when the Pre Out jacks are connected to another amp. The hum goes away when I touch the receiver. The receiver is newly...
