mypasswordis Posted July 18, 2017 Report Posted July 18, 2017 Be careful not to get a linear taper pot, you need audio/log pot for volume
mtaifa Posted July 20, 2017 Report Posted July 20, 2017 If I swap the pot for a 50k LOG, will I have to change or remove some resistors?
spritzer Posted July 20, 2017 Report Posted July 20, 2017 Maybe, can't be sure. I think the board had some resistors and even caps there that should all be removed. In related news, here is the large version of this shitbox: https://page.auctions.yahoo.co.jp/jp/auction/o194170591 KGSSHV alright...
mtaifa Posted July 20, 2017 Report Posted July 20, 2017 Looks to be the same as the small shitbox except a different PSU?
spritzer Posted July 20, 2017 Report Posted July 20, 2017 Also CCS transistors on the main board. Notice the extra heatsinks.
johnwmclean Posted July 28, 2017 Report Posted July 28, 2017 Where’s the best place to buy 009 replacement pads? I have a feeling I’m this is going to hurt.... a lot.

I have a feeling I’m this is going to hurt.... a lot. A couple of years ago I did a detailed search, and only found STAX USA would respond. Suggest you get with your Australian Distributor. Don't believe they are a commonly stocked item, so most dealers won't have them. Expensive. $350 from Yamas at the time. I'm sure he was gouging me as I bought my SR-009s from PJ, and he checked the serial number. Edited July 28, 2017 by Laowei
gepardcv Posted July 28, 2017 Report Posted July 28, 2017 (edited) I just discovered that this exists: https://www.staxaudio.com/ Must be the new US distributor? Maybe @justin knows more? 009 pads listed for $150. No clue if shipping to Australia is possible from this seller, or how much it would cost. Prices for other products significantly lower than the defunct staxusa.com. Edited July 28, 2017 by gepardcv
justin Posted July 28, 2017 Report Posted July 28, 2017 STAX SR-009 3,799.00 The SR-009 is the product of repeated research trip to techology and material search without deviating from our stance to return to live sound and music always with refined sensitivity. looks like it says its woo audio on the about page.
nopants Posted July 28, 2017 Report Posted July 28, 2017 i paid a lot more than that for my 009 pads from hi end workshop
spritzer Posted July 28, 2017 Report Posted July 28, 2017 Can't use 007 pads but it would probably be cheaper to just have some pads made than fork over 350$ for them... Also this site is owned by Woo: https://www.staxaudio.com/about/

Going to try that for my next pair. Have the first pair of pads to take apart the leather and use as templates. The foam will be more of a challenge to reproduce.
aldavey Posted August 3, 2017 Report Posted August 3, 2017 So after four months of ownership my 009's have developed a low level buzz and an intermittent low level whine in the right diaphragm, stays at the same level regardless of volume setting on the KGSS Carbon. When I switch off the amp it continues for a minute or so before stopping. Any ideas of a cure or is back to Stax with them?
aldavey Posted August 3, 2017 Report Posted August 3, 2017 Thanks for the response, unfortunately I don't have any other phones to check that. I kind of discounted the amp, as the problem continues when the amp is switched off for a short while
aldavey Posted August 3, 2017 Report Posted August 3, 2017 Is there a way for me to clear dust if that's the case or should they go back to Stax in your opinion?
spritzer Posted August 3, 2017 Report Posted August 3, 2017 If they are covered by warranty then take them back to Stax. If they are not covered and you don't want to spend 100KYen on new drivers, you can open them up and try to get the dust out of there. Be warned though that you can't see the dust particle causing this as it is minuscule. The space between the diaphragm and the stators is 0.5mm (500um) on either side so the piece is much smaller than that. 1
aldavey Posted August 4, 2017 Report Posted August 4, 2017 Thanks, they are under warranty so back to Stax they go.
Whitigir Posted August 4, 2017 Report Posted August 4, 2017 Noob question but.....Is Stax really that vulnerable to dust ?
spritzer Posted August 4, 2017 Report Posted August 4, 2017 Yes and no. There are solid dust covers on both sides of the drivers ever since the SR-Omega in 1993 (only on the front before that) so the drivers should be sealed but...the plastic is thin and tears easily so stuff can get in. Also something could be in there from when they were assembled as even though they have a clean room, shit happens. Phones such as the old HE Audio stuff, King Sound, Sennheiser HE60 and HE90 all have porous dust covers so crap will get in there over time. 1
judo Posted August 4, 2017 Report Posted August 4, 2017 About clean room. My sr007 had developed an imbalance and when I inspected the drivers I found grey hair under the dustcovers. Not only one piece, was it human hair or from the brush of the Stax technician I do not know. The headphones came from PJ but Stax repaired them after some effort they had replaced both driver. I am not sure either the hair was the cause of the imbalance. I have the picture of a piece of hair somewhere. 1
aldavey Posted August 24, 2017 Report Posted August 24, 2017 So just an update re. my 009 problems. Sent back to Stax, huge respect to them for the turn around time. Received back today as new, working perfectly with my superb Mjolnir KGSShv Carbon. I'm back to where I want to be. 6
