    I'm in,

    Seems like Europe and East coast America are laiden with Sansui, not sure why the west cost is lagging behind?

    Well you could always trade in that hugely over weight Oztralian amp in your avatar for a new Sansui, No?

    By the way, how many transistors does that thing run per side? 12? 16? 24? 206? -I know that it's modular in that the boards are stacked so we only see the top set, just wondering how many more boards et el are lurking below the surface. Must be a wonder to behold....
    What pair of NPN/PNP's does it run? -Would love to look at the specs for the trannies and/or the owners and service manuals for that monster..
    My noggin can't fathom the complexity and veracity of such a huge - pre mosfet- design.

    -much Sansui luv from the frozen north....

    Moe, That amp is one I had back in Australia and was superb. I didn't know much electronics at the time and didn't really open it up and couldn't tell you the details of the particular transistors used. But yes, you are very observant, it has mutiple levels of modular components. The output headsinks are 3 levels deep, with 8 devices per level (4 for each channel) so 24 in total with 12 per side. The transformer was quoted as being 5.5kVA (although their spec sheet attached says 5kVA, but in any case ~5000W!). Those banks of 92 caps are actually 2 levels deep - the idea was to use many small caps to have a fast time constant - total was about 0.3F from those two levels of caps. Mine was biased to about 10W class A, but you could adjust it up to about 30W if I recall correctly.

    220W 8Ohm
    430W 4Ohm
    800W 2Ohm
    1500W 1 Ohm
    (I have seen one of these drive about 8 pairs of speakers simultaneously!)

    rise time 1us
    THD <0.07%, 20Hz - 20kHz
    IMD <0.05%
    TIM "immeasurable"
    Dynamic headroom: 0dB
    output current: 100 Amps (continuous!)
    Response: DC - 150kHz (+/- 0.2dB); DC-300kHz (+/- 3dB)
    Phase: 0deg at 1Hz, <1deg at 20kHz
    Hum and noise: 110dB below rated
    Output damping factor: 220 (DC-50kHz)
    gain: 30dB
    input impedance: 2kOhms balanced
    Transformer: quafilar secondary C core rated at 5kVa at 5% regulation
    PS cap: 92 in parallel adding to ~300,000uF
    Weight: 54kg (119lbs) !!!

    The company, "ME" (which I think stood for Modular Electronics) had been out of business for over a decade, but there was always promise of a come back... and it appears it might be happening although it is not clear if the original guy (Peter Stein, whose signature adorns the higher models) is fully involved. Will start a thread over in Solid State forum.

    I love my Sansui, and they actually led to me selling this beast, but that was partly because it was in Australia and I am now in the USA. It was the only big amp i tried out that was powerful but still 'warm'. Can't explain it. I've also never heard another amp that would grab the speakers by the reproductive extremities and tell them what to do. Truly amazing amp that I miss a lot.
