    Is there any relationship between the Sansui equipment of old and the
    Sansui branded audio gear sold by the Strathfield Group and
    distributed (?) by the Yale Appliance Group?

    Yale's Sansui logo looks nothing like the original:

    Is this some clever marketing ploy to cash in on the goodwill of a
    well recognised, albeit defunct brand name?

    ** Very unlikely - in the sense of a continuity of design and
    manufacture.


    ** Logos can get an update from time to time.




    ** Famous brand names never die - they just get new owners in
    different parts of Asia.

    Yep, the modern reality is that its a hell of a lot cheaper to
    have some low wage asian stamp one out on a production
    line in asia than it will ever be to have some relatively
    expensive first world tech repair it now.

    Been like that for years and years now with the cheaper
    domestic appliances, and that basic approach is not the
    only thing that makes any sense with VCRs, TVs etc too now.
    Plenty of them are cheap and not crap at all.
    Because the replacement is so cheap, stupid.
    Because no one with any sense repairs them anymore.
    There's still a few around here. Makes no real sense to use them tho.

    And board changing is all that makes sense with PCs too,
    for the same reason. Its often a good excuse to upgrade too.

    of manufacturing> cheap, low end junk. Cheap, crappy power transformers,
    plastic chassis

    ** TW is selecting his facts again - all the 70s Sansui amps were
    well made.


    and Jensen is about to be orphaned in

    ** TW is off his head. Phase Linear was a major status hi-fi brand in
    the 70s.

    By the early 80s the factory was closed. The designer went on to
    create the Carver range and his technical staff became the Rane Corporation.



    Hell, their power amps could not even maintain high power outputs, without
    fan

    ** TW is off his head - domestic hi-fi is not a PA system.



    Their preamps.....well..... the less said, the better. Utter

    ** TW is off his head - period.



    ** Yes. TW is about to produce a rare exception so I will snip it.



    ** Shame about all the folk that do just that then.

    TW is a waste of space.

  5. **Oh really? Tell me about:
    A303
    A505
    R505
    G3300
    D90
    D100
    Full auto turntables
    Etc.

    All employed poor construction materials and techniques. Output devices, for
    instance, were pressure mounted, by mild steel to heatsinks. Over time, the
    output devices no longer made proper contact with the heatsink. The cassette
    decks employed ALC and poor quality mechanics, requiring constant
    replacement of idlers. The turntables were just plain horrible The clutch
    mechanisms, driving the arm mechs were constantly failing. The mid range and
    high end Sansuis were reasonable. At least as good as the competition. Their
    low end stuff (which they sold lots of) was just plain old crap. Those of us
    who serviced it (which you clearly have not) know it well.
    **Dream on. It was built to provide the most number of Watts, for the least
    number of Dollars. Nothing more. How much was a Phase Linear 700 in 1975?
    **The Phase Linear amps (400 & 700) were not able to meet the IHF
    pre-testing conditions, without fan assistance. They employed pitifully
    small heat sinks.
    **OK, Phil. I have a Phase Linear 4000 preamp here. You can service it
    anytime you wish. I'll pay you one hour's labour. If it's so damned easy to
    service, you'll come out way ahead. Seems fair to me.
    **Hardly a rare exception. Sony were producing reel to reel machines in
    Singapore, back in the 1970s. They performed just fine.

    (snip drivel) The topic was amps - see above "amps" !!!!


    ** TW has no clue what I posted.

    He thinks I posted somethig else.



    ** Everyone complained that IHF test was way WAY too tough.

    PL amps were fine in practice.

    ( More TW irelevant shite.)



    ( snip shite) TW - the topic was *not* servicing.



    ** TW - that is the reverse of the topic.

    You are off your head.

    ** So what - they are ones nobody bought.

    70s Sansui means the famous AU series in the minds of eveyone
    except you.


    ** Irrelevant.

    ** Usage contrary to instructions.

    TW is off his fucking head.


    ** You were replying to my post.




    ** Exceptions only prove that exceptions exist.

    TW is a fallacious debater.

    Go read my ten cheats again.

    How many bits did a Philips CD100 convert ???????



    ............ Phil
     
  8. **You would be wrong. Those are the amps that MOST people purchased.
    **YOU said that. I did not. Moreover, the thousands who purchased the cheap,
    crappy Sansui stuff (and the techs who serviced them) will know EXACTLY what
    I am talking about. The AU series Sansui stuff was, indeed, excellent. Their
    cheaper stuff was not.
    **Unless one was required to actually meet the IHF specifications, of
    course. Funnily enough, many, many other decent amplifiers, managed to pass
    the IHF requirements with ease. Phase Linears could not, because they were
    simply built to provide maximum power, at minimum price.

    The last Sansui amp I remember repairing was an AU4900. I was
    surprised to find that its designer had created a full wave bridge
    using eight 1A rectifiers connected as four pairs of diodes in
    parallel. He/she was apparently under the misconception that the
    bridge could now handle 2A. I was shocked to see such a fundamental
    error from a high end (?) brand name. Fittingly the fault was shorted
    rectifier diodes. Needless to say I rebuilt the bridge with four 3A
    versions.

  10. **A very common problem with this model. Another common fault was noisy tone
    amp transistors. A bugger to find and fix. Ironically, you saw one of the
    BETTER Sansui models. You should look at the ones which used plastic chassis
    parts, mild steel (they could not afford spring steel??!!) retaining systems
    for output devices, no VI limiting circuits and other cost-cutting moves.
    With junk like that, it is no wonder that people stopped buying Sansui.

    ** I did, and it is true.


    ** IHF did not require enclosed spaces and no fan cooling.

    Phase Linears could not, because they were

    ** Paralleled power diodes work fine.

    The error is all yours.



    ................ Phil
     
  13. **Clearly you have not had to service many of these amps. Power diodes and
    tone amp transistors were VERY common failure modes. In the last 25 years, I
    have probably replaced diodes in several hundred of these amplifiers. FAR in
    excess of similar amps, from other manufacturers. Other manufacturers chose
    (correctly) to use single, large diodes, or appropriately rated bridges.
    Sansui, for reasons best known to their designers decided to ignore good
    engineering practice and use 1 Amp diodes instead.
    **Nope. He is correct. After replacing diodes with single, higher rated
    devices, the amplifiers never failed (in that particular manner) again.

    Why the silence on this TW ?

    I know why.

    Trevor Wilson is a vile charlatan and a lying turd - that is the
    reason.

    Not at all. Look closely at the knee in the diode characteristic and
    then tell us how current can be evenly shared by two parallel diodes
    with even a *slight* mismatch in the I-V curve.

    Hint: dI/dV is *very* large.

    ** Just try it Frank - you have NOT tried it.

    Get two 1N4004 diodes from the same batch ( like any manufacturer
    would) and TRY it.

    I have - so I know.

    I made over 100 guitar amps with this 25 years ago - not ONE
    diode failed.

  20. It may well work, but it is very poor design.
