    His Spec 4 meters are peak reading and he's playing music, interpreting the +3dB meter ballistics swing as being 'real' watts. A Spec 4 barely hits 180w/ch both channels driven in a tailwind. Even that would vaporise the Sansuis.

    90 watts continuous sine wave would take them out, but then again, 90 watts continuous dissipation is an awful lot for any vintage speaker long term. Peaks, sure, but hour after hour- no way.

    Pretty much what I was thinking that he can't get the power out put form UV meter, far far too inaccurate. I also doubt his power transformers will hold that power for anything but the instant high peaks. But the speakers do handle 180 watts but start distorting, however at 8 feet away you might be able to listen to a song with 150 watts leaving a little head room, but we're talking very loud.

    No way, my thread and hands on knowledge. :rolleyes:

    Proud owner of the SP-5000 model!
    Mated to a fully restored Pioneer SA-9800 (rated @ 100 wpc). Thinking about two things: 1) adding a tube pre-amp to amp up power (pun intended). 2) recapping the speakers.. But worried about altering original sonic presentation. Also, reading different opinions on type of Caps to potentially use; film, electro, or poly (I think - sorry.. Brain fart).

    Any input would be much appreciated!

    Thanks

    Ok, I'm officially entering this fray with pictures.

    When I first posted here I'd just bought a pair of SP-5000 in Vancouver, WA. The guy's barn was stacked with equipment so tight that amps were on their sides, stacked like books on the shelves. He told me these speakers were recapped. I didn't even know what that meant. They sounded fantastic and they were 95% clean. I paid $400. Very nice wood. I struggled to carry them into my house and hooked them to my Sansui AU-717 and I've been blown away ever since. Astounding speakers. I've heard $10,000 speakers and honestly I think these high end Sansuis are a hidden sleeper of the audio world.

    So when I was in New York last month I tracked down two more pair. One for $125 and the other for $200. So now I have a six pack spread across the county. These pairs were both uncapped and both about 50% on the clean scale. They might have lived in a dorm room by the scratches, but no one spilled beer on them that I can see. It's moist on the east coast and I bet these spent time in a basement; the screws on the back of one of the four were so corroded that four screws just stripped their philips slots and I couldn't get the back off - yet.

    So these four uncapped purchases sit in a friend's garage in NY for the moment. I want to recap them myself and I'm looking for some advice on that process.

    Having read a little about capacitors and immediately noticing the vast difference between my first recapped pair and the two non-capped sets I bought in NY" I am sold on recapping. It's night and day. I'm even considering a recapped AU-717 on ebay to see if recapped amps benefit to the degree that speakers do. Anyone got feedback about that?

    Here's the original crossover with purple caps and a pic of the recapped crossovers. I see that whoever did the job sometimes used two in place of one, adding up to slightly more 'MFD' with the new caps. (What's MFD?). My instinct is to copy exactly what I see in the recapped pair to match the other two pairs. Clearly I'm a newbie to electronics, but I'm a sculptor by trade. I can tig weld and braze and I'm sure I can solder just fine with a little practice.

    So I'm hoping people can throw in their two cents concerning the best move with the caps:

    1. where to purchase caps.
    2. whether to copy the set up I find or is that a hack job someone did because they just used what they had. why two in place of one?? Is that a special technique?
    3. what's the best soldering iron and solder for this job?

    Thanks in advance. I've gleaned a lot from this forum and I really appreciate people's input.
    And I am blown away by the sound coming out of these damn speakers. WOW.


    ps. does anyone know what the 'red dynamite sticks' (last picture) are. They weren't changed in my recapped speakers.


    THX!

    Yes like night and day after a re-capping...the volume of sound that issues forth from them without distortion is amazing!

    I'd like some help from an sp5500 owner if anyone would be willing to take the time, it's not a small task I'm asking because you'd almost have to if not completely have to dismantle one of your 5500s to help me, I have a set of 5500 components that I've purchased I'll be getting within the next couple weeks and I want to build a factory spec cabinet for them, everyone who frequents this post knows the rarity of 5000/5500 speakers and finding specifications such as that even on a way more common 2500 would be impossible without the cabinet right in front of you, especially the dimensions of the internal braces and bracing blocks, I could make a cabinet that "fit" the drivers no problem and it would be close but not close enough to be an actual 5500, I'd be using correct materials as well so thickness of all pieces would be needed to including the internal absorption fabric and all dimensions of routed edges as well, I'd be documenting the process of this as it went but with life being so hectic I don't see it being a quick project nor would I want it to be, after the fact I'd like to invest in some walnut burl veneer and make this thing pop like never it never could before it was dismantled, the other issue is the grill it's an impossible "part" to find and I'd spend forty years trying to carve a kumiko grill by hand, if anyone knows how to make them or someone who does that info would be appreciated, I'm asking a hell of alot out of someone if anyone is up for this please do reply and by no means do you have to rush I'll be taking my time to acquire the materials and do it perfectly so I'll need in the neighborhood of 200-300 in materials first off, the only part I'm throwing around changing is the build of the factory stands, I ripped the ones off my 5000s they had served their duty and were way worn the speakers look way more hefty without the lady legs on them

    My latest haul. A pair of SP-5500 stored since the Vietnam War era. Lot's of mouse droppings all inside the one shredded box.
    Some staining (see second pic) but basically a nice pair of SP-5500. Just need recapping. They're out there. Not always cheap. But they're available.

    Honestly I'm not even going to think about how hard the work you're talking about is going to be. I think the grills, especially these curved ones, would take a life time of skill to produce. I say keep your eyes peeled. I've seen four pairs of 5500 and three pairs of 5000 in the last six months. I bought all the 5000s and one pair of 5500.
