    Swiss Marantz 1090 : cleanup and rebuild

    Hi, it's probably better if you start your own thread. This is an old thread. If i remember correctly my volume control also had a mechanical problem that I was able to fix. But it is delicate and you need good skills.

    Question for owners of SVS-SB1000 subwoofer

    Here is the reply from SVS : "Bertrand, When SVS designed the Sledge STA-300D platform, we struck a fine balance between an acceptable S/N ratio (i.e., noise floor) and the overall DSP gain structure and gain sensitivity required in order to allow the amp to be driven to full power with typical...

    Question for owners of SVS-SB1000 subwoofer

    Ok, SVS were very quick in answering my mail, even on a sunday :) I've sent them a video and apparently this is considered normal for the SB-1000 :dunno: I'll put it back in service and try and forget about this :idea: :rflmao:

    Question for owners of SVS-SB1000 subwoofer

    Of course not :) But I expect a modern product like this to be 100% silent with zero signal and everything but the power cord disconnected. A tiny hum of hiss would likely not bother me, but this garbled noise does :rolleyes:

    Question for owners of SVS-SB1000 subwoofer

    I have not tried contacting SVS directly. That's probably a good idea, thanks!

    Question for owners of SVS-SB1000 subwoofer

    Hi all. I have a question regarding the SVS SB-1000 subwoofer. I've had mine for around 6 months, and lately I've noticed it's making a soft rumbling sound. I'm not sure it was there from the beginning. I can only describe the sound as something like "blblplprplbrblbpblpll" o_O:D It's definitely...

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    No wireless soundpath here, only wires. And the sound is there with ONLY the power cord plugged in, I tried different mains outlets as well.

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    Hmm, interesting about the Wi-Fi interference. My router has a switchable wifi, I'll give it a try.

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    Hi Stsang, sorry for the late reply, I'm not much on Ak these days... I'm happy with the sound of the Sb-1000 and it's size and power. I don't need high volumes much. Unfortunately it's now waiting to go on a warranty repair, it has developed a low level sound that is always there as soon as...

    Revox B285 noisy left channel - need advice

    Just to let you know, I found the fault. It was a BC546B transistor on the main amp board, there are 4 of them on this board so they all got changed. How did I find the faulty part ? 1 - narrow down the possibilities : only on channel noisy, does not change at all with ANY control like source...

    2SA1265 / 2SC3182 substitutes ? blown Marantz PM75...

    @avionic thanks ! I did not realise the 2SC3858 + 2SA1494 were MT-200... So what is more appropriate, A1492 / C3856 or NJW0281G / NJW0302G ?

    2SA1265 / 2SC3182 substitutes ? blown Marantz PM75...

    Hi all, I was given a very clean but defective Marantz PM-75... First diagnostics showed a blown mains fuse. After unplugging power to the power amp, the fuse does not blow anymore. So I disconnected all 8 power transistors and found out at least 5 are fully shorted out :eek::D. With the output...

    Revox B285 noisy left channel - need advice

    I realise this is best (did quite a few full restorations on seventies' Marantz and Yamaha amps). But the unit is not mine and I'm not sure the guy wants me to go ahead and start some expensive work.... Are bad electrolytic or tantalum caps actually "able" to fail in this way (crackling static...

    Revox B285 noisy left channel - need advice

    Hi all, I have this nice Revox B285 button monster (actually I don't like it, it's not mine :D), it has a noisy left channel. There is some hiss but mostly static and crackling. Here is a link to a video I made, the sound is not actually very loud, but I had the microphone very close to the...

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    Thanks all, I now have the SVS SB-1000, it's nice, I'm starting to be happy with the settings, little by little. I might have to play with placement some, but I'm quite limited...

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    thank you @bberkom. Yes I'm thinking the SVS will probably be the better option. We'll see, I haven't ordered anything yet.

    subwoofer : B&W ASW610 or SVS SB-1000 ?

    Looking for recommendations on a subwoofer I'm looking at the B&W ASW610 and SVS SB-1000. These 2 are the right price and size for me. So around 500 - 700 USD and 13 inches / 33cm cubes I've read very good things on the RSL speedwoofer 10S but they are not available here in Switzerland. My...
