    How to Properly Ground Pioneer SPEC-1, SPEC-2, and Other Gear?

    Hi everyone, I have a vintage Pioneer setup, including the SPEC-1 preamp, SPEC-2 power amp, SG-9800 equalizer, CT-F1000 cassette deck, and RT-707 reel-to-reel. I've noticed static on the front panels, especially when I touch them. I suspect this might be due to improper grounding. (NO HUM OR...

    Chassis ground screw missing on 2235

    Putting together my first system and I went to connect my turntable ground wire to my 2230, but I noticed the ground screw was missing. Is it as simple as putting a grounding screw from the hardware store in there or do I need an actual part for that? I’m not electrically savvy so I want to...

    Simple (hopefully) question about chinese p.supply grounding

    Hello everyone! I have this one simple (I guess) question about grounding DIY amps. I have an old Sony amp/receiver that doesn't work. I have also ordered chinese DC power supply and TPA3255 based amp board. So I thought that I could reuse the chassis from the Sony. I want to use IEC connector...

    Pioneer SA-9500 : Troubleshooting Noise

    Hi, I bought the SA-9500 new in early 1977, but pretty sure it is a 76. I have never serviced it. It sat from about 1990 until last year (2020) when I brought it out to use with my phono system. So was used almost every day for 16 years. I opened up and did basic cleaning and once pots and...

    Sansui 2000a Service Bulletin Clarification.

    Complete noob here so excuse my ignorance if this is obvious to others. I had initially posted this here the "Exclusively Sansui" section, but perhaps this forum is a better fit. I've replaced the faulty transisters in my 2000a and it got rid of the popcorn static. It still has a slight hum or...

    Laptop Charger As Power Source

    I realize that all wall worts are not made the same, so is a laptop charger a good, quiet, low interference source of DC power? If so, I’ve wondered now for a while, what of ground in a DC circuit that’s not rectified from AC such as a battery powered head amp for MC phono signal boost? And how...

    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...

    Thorens TD160S MkV - Speakers are picking up radio signals!

    Hi all, I'm looking for some advice from Thorens owners. I've just bought a nice TD160S MkV on eBay and fortunately it has arrived in one piece. I've not owned a Thorens before. It has a Grace 707 tonearm and the RCA leads are also Grace. After having spent a few hours putting some things...
