We need pics to officially put you in the 5000 club......
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!
