  1. Hi, been lurking for a while but finally signed up! Quick background on my gear: I'm in the Stax ecosystem with an L700(Mk1), SR-3, and an SRM-003. I also have a D10 and T1S, the latter of which was on a shelf unused in the original box for 25 years or so and last year I bought it. I'm still planning to recap it and upgrade it with the constant current mod, but that's to come soon. In the meanwhile, I came across a curiosity online, a homemade normal-bias tube amp. No real info provided, but it was a reasonable price so I took the shot in the dark, and I don't have the electronics kn
  2. Hi all, I’ve lurked here for a while but am active in the other regular forum. Apologies for the cold post here, but after a trade and drunken bidding on Yahoo Auctions I find myself with both an SRM-T1S and a 006t (both have pro and normal bias outputs). I would like to get the CCS mod done to one of them, likely the 006 which I would then keep. There’s likely no way in hell I would trust myself to do the mod, though I have JimL’s article. So my post is to find someone who could upgrade my 006t with the CCS mod and whatever other upgrades and updates (and voltage change) you feel wou
  3. Hi y'all, Got my entry ticket into the Stax world in the beginning of 2018 with a Lambda Signature SR-407 earspeakers / SRM-T1S energizer combo. Got them from a Japanese seller and therefore I'm having to use a 100V step-down transformer for Japanese electronics here in Brazil (power outlets at home are 127V, 60 Hz). Only recently got the nerve to open the energizer to remove some dust and check the components (a bit scared of touching those big-ass 100 uF caps, but an anti-static brush and a lens cleaning blower sort of did the job). As far as I could see, all components seem origin
  4. Hello all, I'm working on a little project with my old SRD-6 energizer and a cheapo TA2020 amp. I'm trying to put together a compact transportable setup for my SR-5s. I have done a few modifications to this box already, such as wiring the transformers directly to the speaker taps on the back of the box and directly to the Stax socket on the front, completely bypassing the bias board and the loudspeaker switch. Those mods have done great things in terms of sound quality, but what I'm interested in now is modifying the bias circuit to operate as a self biasing one. As I understand it, Stax accom
  5. Hi all, I was advised by some head-fi members to inquire about the technical aspects of this amplifier here. Do let me know if I'm failing to follow any rules; just trying to avoid any catastrophes! Here are the photos of my amp: https://imgur.com/a/sshHA7B The amp is an 8FQ7 SRM-007t rated for 100v 50/60hz outlets. I have a step down transformer (PowerBright) rated for 120v to 100v, and my outlets are, I believe, 120v at 60hz (American). The transformer works fine with my Japanese SRM-252S, but the fuse has blown 3 times now when turning on the 007t (always the 2nd time it turns on;
  6. Folks, I replaced all the electrolytic capacitors in my SRM-600. I can't say for sure if this has happened before, but this (photo) capacitor at 10V 4700uF is heating up. Not very much, around 55C. The headphones aren't plugged in. Can you tell me if this capacitor is in normal operation? Does it have to warm up? My SRM-600 for 230V voltage. First, I supplied a cheap Jamicon TKR472M1AJ26 capacitor. It was heating up.Then I decided to place EEUFR1A472L Panasonic Low ESR capacitor. However, it's warming up, too. I checked the diodes next to it - they're not broke. O
  7. Hope you guys don't mind, but I'm taking the liberty to collect some info, links etc. here. 900V floating supplies 350V/us the cole slew (couldn't resist) seems to be happening in bits and pieces in multiple threads on multiple forums and there are some implementation issues which seem to be worth discussing...namely fitting all of this somewhat daunting amplifier into one case. I guess at some point Kevin decided to split the input and output stages- output board output schematic The output stage features the floating supply floating supply fboard floating supply schema
  8. Hey all , so this is my first post here so sorry if its not up to par. Recently i bought a Srm-006t amp 404 signature combo . I loved the sound but it seriously lacked volume . I replaced the tubes with a new set of EH tubes .. but aside from a uptake in tone .. I didn't get any extra volume . I started searching Google for mods to this energizer and came across a post by Kevin about a cascade mod for this amp and mention of an article in Audio Express July 2017 edition by James Lin. In the thread i was reading i saw that a board had been designed (im really not a fan of point to p
  9. After a few weeks burn-in period of this little beast, I found it's very relaxing to listen to. I can hear more juices coming out and the STAX 009 just doesn't have that analytical sounding cliché to my ears. It also enhances the soundstage and life-like of Focal Utopia makes it way more enjoyable to hear. This is a push-pull design tube Headphone Amplifier/Preamplifier attempting to achieve the true high-performance of headphones from Dynamic, Planar Magnetic to Electrostatic models. I've gotten a few PM's asking about the schematics and stuff so I decided to open a thread to discus
  10. Dear fellows, Maybe you can help me with an advice. A friend of mine gave me a Koss head amp E/9B but without the suited headphone. I want to know whether it is possible to play a Stax headphone (normal or Pro Version) through this head amp. If it does not work - it is possible to convert the Koss working with a Stax headphone, maybe by building an adapter? Many thanks in advance. I wish you a great happy new year 2018. Best, Andreas
  11. Thought it might make sense to make a new thread on this so as not to pollute the T2 thread. So this would be limited to the chassis, any potential board run, and any other potential group buys for traffos or transistors (if numbers warrant). I am hoping to move forward by the end of the week. Please keep in mind, if you are in and make your deposit, you are committed and will not back out unless you find someone to take your spot (so if you are not well established, then paypal gift only). Please express interest here or by PM. I have also included a link to the results o
  12. Hello My little amplifier for my Stax headphones. First stage is based on ECC82. One triode per channel as cathodyne phase inverter. The second stage is 6N1P-EW with CCS, and power stage is with E80CC with CCS too. It was designed to work with my PC to drive Lambda Pro. So output voltage is not so big 308 V peak-peak, but it is enough for Lambda Pro.
  13. I recently acquired a set of SR5N earspeakers, with white color. I am asking that how can one's decide if it is a gold editon or not?
  14. Due to my impending move at the end of the month to a new and bigger house it is time to have a moving sale. All the amps I have in stock (so not the KGSSHV Carbon as I can't make enough of them) are included plus all the special items I have as well. They are all discounted by 15% and free shipping worldwide is included. See the News section of my site for a complete list of everything included or just click here. The sale will run from noon today (UTC) to midnight on Sunday the 17th. Everything is in stock and ready to go so shipping is expected a week from final payment. Could b
  15. hi all, i am a new owner of a lambda SR. i found it cheap on craigslist, was not expecting to see one, went and snatched it up for cheap. it looks fairly dirty on the inside and i have been looking at some guides where people describe cleaning lambdas but the process is a bit intimidating... it looks like there is a lot of dirt inside. i wasn't aware dirt was so hard to clean off of them before i bought them, and there are 2 visible specks of dirt on the left driver on the inside. that driver usually buzzes a bit, sometimes not too bad but sometimes a bit louder. when you look down into the dr
  16. I've got a Studer amp to keep my Stax menagerie under control via the SRD-7 Spritzer. It has always had quite marked mechanical hum when run at 240V (Australia's mains voltage). I have a 240 -> 110V transformer and the Studer is able to be configured to almost any possible mains voltage via a rotary switch and with a change of fuse. Did that. NO FREAKIN' HUM! $2.50 for 2 new fuses! Love it.
