    Sansui 4000 capacitor question

    I am in the middle of recapping my Sansui 4000 receiver. When I removed the bottom cover I noticed 2 capacitors labeled “.039 uf KCK” have small cracks near the leads. They are located near the middle right hand side when the unit is upside down. Since I purchased a recap kit off of eBay...

    Sansui 4000 Clean Up and Issues

    I acquired a Sansui 4000 (along with Sp-2000 speakers) recently. It wasn’t working at first, but I cleaned the pots and it started working. The tape monitor button was not holding, but this was not a big deal, I was mostly using the aux and occasionally the phono. However, I just acquired...

    New member. Sansui 4000 "projector" light issue.

    Hello all, I hope everyone is having a lovely Monday. I am very new to vintage audio and receivers. I did a somewhat steady amount of research before buying a Sansui 4000 receiver. Purchased as working with no known flaws. I have had it in my possession for a little over a month now, but have...

    Sansui tuner lights out

    I recently purchased a Sansui 4000. I’ll start by saying that I’ve owned a few high end modern and vintage receivers in my life and this one is by far the warmest and musical components I’ve come across to date. Hard to describe but the sound is full and thick… love it. But that’s not why I’m...

    Sansui 4000 1969 test report reprint

    Recently I came across the following leaflet: An original Sansui promotional reprint of a 1969 AUDIO Magazine test report of the Sansui 4000 receiver. As far as I can find, this old test is not available online. So here it is. I think it is readable, despite my poor picturing and the low...

    Sansui 4000 "protector" light always on

    I recently rescued a Sansui 4000 from storage in my basement. I'd never opened it up before, but somebody had. (There's a little spring jerry-rigged to hold up the tuner indicator wires.) The first thing I noticed as I was about to do a little cleaning inside was that the PROTECTION lamp was...

    Feeding the Sansui bug

    I think it bit me. I remember Sansuis from the '70s, which were talked about in tones of awe rivaled only by McIntosh and Marantz. My first equipment as a teenager was mainly midline Pioneer, Kenwood -- still good-sounding and good-looking stuff -- but about five years ago I bought my first...

    Sansui 6060 vs. Sansui 4000?

    The Sansui 4000 I use every day. I love this reciever. It is also the only Sansui I’ve ever heard. Because I’m bored I am offering to trade a Marantz 2238 through craigslist and have been offered a Sansui 6060. The 6060 is a later model than the 4000 and both around 45 watts - different build...

    Sweet Spot - Sansui, Dual, Dynaco

    Currently in my happy place. Surely, most like me get sucked in and fiddle and fiddle and seek perfection (within financial means) - but then reach that moment, where everything is correct, and there is nothing more to do. And the music sounds the way it should, for the moment. Sansui 4000...

    Samsun 4000 suddenly snap crackle one channel, cleaned and still persists

    Darn spellcheck in the title and Forum won’t let me change title. My SANSUI 4000 has been working well for a couple years. I had cleaned all the pots and switches after finding out a yard sale and everything was fine. This week I started getting a snap and crackle out of only the right channel...

    Sansui 4000, Distortion on Both Phono Channels

    Hey everyone, I’m brand new to the vintage world, and I picked up a Sansui 4000 receiver yesterday and have come to find that there’s some pretty nasty distortion in both the phono channels. The signal seems much louder than it ought to be. Additionally, I can hear signal from Phono 1 while the...

    Help with Humming 4000

    I picked up a Sansui 4000 this week from a local vet who was downsizing and getting rid of old stereo equipment. Purchased in the Philippines in 1970 or so, it, along the SP-2000's that came with it, had not been used in years. The 4000 was dirty but it, and the wood case, are in over all very...

    Sansui 4000 Buzz and other issues

    Hey guys, I just picked up a Sansui 4000 that was recapped and has new LEDs, but I'm having some issues. The first and most minor issue is the FM Stereo light is always on. That's really no big deal and I knew about that. Next issue, it makes a pop when you switch it from FM Mono to FM Auto and...

    Sansui 4000 Issue

    I recently acquired a Sansui Series 4000 receiver at a used record shop. For $25, I figured it was worth taking a chance. Brought it home, cleaned it up, and hooked it up to my turntable and Advent loudspeakers. The sound was amazing and I couldn't believe my good luck. The next day, after...

    4000 sound not as full

    Just got back my 2000x and the sound on it is so much fuller when compared to my 4000. More mids, bass etc when doing a 1:1 comparison with all audio setting equal. The 2000x just had some capacitors replaced. Could weak capacitors be a culprit to why the 4000 lacks the punch of the 2000x...

    Sansui 4000….harshness

    I recently picked up a Sansui 4000 receiver. I have had a tube amp before and wanted to see if could get that warm, fuller sound without the hassle of tubes. I'm new to the vintage receiver world. Everything seems to work well with this receiver. However to my ear the sound is somewhat harsh...

    Sansui 4000

    Hi, my first post. New to audio as well, looking to buy my first receiver. I only have a turntable so far. Anyway, looking at a Sansui 4000, price is $225, which seems high to me based on my research. Thoughts? Never been serviced, one owner, so he says. Not affiliated with this listing...
