  1. Trying to fix the issue with this Luxman amp. Takes a while to get out of protection on start-up. When outputting more than about 1W, speaker makes popping sound, if left playing, makes one really loud pop and turns itself back to protection mode. I took it open and got some pictures. Seems like the amp had been repaired before. One of the amp board looks like it's been blown up before. the main power transistors looks different on the power amps, is that a concern? The 2SA679 is swapped for 2SB655A and 2SC1079 is swapped to 2SD675A. Any ideas what would be causing the issue? Any help is appreciated.
  2. Dear audiophile, I'm just wondering whether anyone could recommend an experience and qualify service person to do the following with reasonable fee and charges. . Vintage stereo restoration . Vintage stereo clean up and revitalise . Turntable proper set up, cartridge installation and alignment.... Many thanks.
  3. Hi all, This is the first time I'm posting. I have recently purchased a pair of KEF Reference model three speakers (made in1994) and am in the process of acquiring an amp. I have so far auditioned (with my speakers) a Naim 150/112 flatcap combo, Musical Fidelity M6i, and will soon be testing a Trigon energy amp. To my ears the Naim setup was far superior to the Musical Fidelity which had more volume but sacrificed just about everything else. I have also hear a friends vintage luxman 308 paired with KEF 104/ab speakers and the sound was very impressive! Unfortunately I no longer have the opportunity to audition my friends amp with my speakers. So my question is, would a vintage amp such as this (or better) perform well on newer speaker systems such the KEF models I have? I understand the answer depends on a whole range of variables but just in general terms would I get more bang for my buck with a newer second hand amp or a vintage amp which made a name for its self in the 70s or 80s. I guess the main aspect I am concerned with is clean, detailed sound quality. My budget is not yet set in concrete but somewhere between $1500 and $3400 depending on what it would take to satisfy my ear. Any thoughts would be much appreciated:) Thanks!
  4. Hi All, I have been lucky enough to pick up this big girl from yet another collector from Melbourne. Picked it up for a fair price and had it shipped up undamaged *phew!* only issue is that the tone switch was cutting out the left speaker (must have been due to transit). A bit of jiggling and actuations and she sings beautifully now. First things first, I am amazed at just how accurate and musical sounding this amp is.. I have been playing just about everything on her Flat (no treble/bass increase), it is similar to my Yammie CR2020 receiver but definitely packs more punch! She loves Jazz, all my Norah Jones, Enya, Celine, Alicia, Sarah Mclachlan cds getting their workout. There is no colouring in the sounds at all, what you put in is what you get out. Compared to my Marantz pieces which has a very beefy, boomy (some would call this 'Warm') bass. The 919 packs a nice clean bass and past 12oclock, she gets loud. really loud! I am sure she is well over her 100wpc conservative rating. Great news also is that the unit has recently been serviced, with the seller advising that all the 'glue' has been removed and 'some' caps replaced. Although I haven't had a chance to opened her up yet. I have been enjoying her as is. I think where the 919 really shines though is the mids and highs, she produces a very clean sound at the top end that my Krix Lyrix Gold just hasn't been used to. Even with my Yammie CR2020, which is still a great amp, I have not heard such clarity through my speakers. I am blown away and it has far surpassed my expectation of a TOTL big daddy amp. Prior to the purchase I called John (skippy124) up to pick his brains - Thanks John Lol. These amps are rare and I have not seen any come on for sale in my time searching. Only downside I can think of is this... my amps are starting to breed which is raising a few eyebrows (and fists) from the wife. LOL I am becoming a Sansui Tragic.. what's wrong with me -Daniel
  5. Item: SANSUI AU-101 Amplifier Location: Brisbane Price: $300 SOLD Item Condition: excellent!! Reason for selling: need to pay of the cost of buying a tube amp Payment Method: Pickup - Cash or Direct transfer. Will post at buyers expense (estimate/approx $35 Oz post) Extra Info: I am the second owner of this supurb sounding Sansui amp. The amp was looked after impeccably by the first buyer (circa 1970's!) and there are no scratches or marks on the body, likewise the side wooden panels are in perfect condition (with original stickers). The amp was entirely restored and fully tested by a qualified technician 6 months ago - replacing the diodes and transistors (notably the output ones). The performance of the amp is well suited to vinyl. The phono stage is excellent - I have been using my old NAD 5120 TT and the sound is very detailed and rich. I have also been playing my digital files (itunes+Audirvana+SchiitDAC) through it and the sound is fantastic. Comes with the original laminated information & Data sheet. http://www.vintageaudiobliss.com/2013/12/sansui-au-101.html http://www.hifiengine.com/manual_library/sansui/au-101.shtml Description The Sansui AU-101 incorporates many of the state of the art features of the more powerful AU-555A, including an all silicon solid state design, professional arrangement of controls and a satin black control panel. Like all other AU series amplifiers, the AU-101's tonal quality has been perfected and proved not only by precision electronic measuring instruments, but also by repeated listening tests in a wide variety of environments. Specifications Power output: 15 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 60kHz Total harmonic distortion: 0.8% Input sensitivity: 4mV (mic), 3mV (MM), 200mV (DIN), 200mV (line) Signal to noise ratio: 65dB (MM), 75dB (line) Channel separation: 45dB (MM), 45dB (line) Output: 200mV (line), 30mV (DIN) Speaker load impedance: 4Ω to 16Ω Semiconductors: 18 x transistors, 4 x diodes Dimensions: 407 x 115 x 278mm Weight: 5.9kg Please feel free to contact me for any further info or an audition. Am in Woolloongabba, Brisbane. Pictures:
  6. Hello everyone, For some inexplicable reason I have been running a 1970's vintage stereo setup for a few years now (Thorens TD160, Marantz 1030 and Whafedale 306) - probably to do with nostalgia and being a cheap skate rather than hi-fi-delity, but it sounds fine to me. The amps have started breeding and I now have about 5? One is a Sansui AU101, which has now developed a loud humming/buzz and "bitten the dust" and was on its way to japanese amp heaven. But having read the pete_mac post ( http://www.stereo.net.au/forums/index.php?/topic/51043-sansui-au-101-resto-and-upgrade-for-snaer/ ) I decided to try to the recap thing! Nothing to loose. Could I ask a few questions before I start buying/soldering and perplexing, please refer to the picture I have attached which shows the gubbings of the amp. I have labeled four sections in the pic..... A, B, C and D. Referring to A and B. There are 4 resistor thingy(ies) missing but the amp was working OK, should I add these back? Very strange. Referring to C. There is leakage at the bottom of the big blue capacitor - is this an indication of a good cap gone bad? Also may indicate pale blue are original caps? Referring to D. There are a mix of pale blue and grey capacitors, are these all original or has a partial recap be performed already? Anyways, I thought the best course of action is a total recap of all based of the approach of pete_mac (and others). Can anybody suggest a "set of capacitors" or an (australian) supplier (jaycar?), I have a low res copy of the owners manual (from the WWW) which lists the originals but I'm not sure where to start. (I can post this if needed). Sorry if this is in the wrong forum but this is my obligatory introductory post. When I have a bit of time I will troll through the forums to get a feel of the discussions. If anyone is interested I'm happy to put together another post into another forum on recapping the amp when I've finished (from a beginners perspective!) Mark
