Those extra terminals have to be for isolating drive units for some reason, measurements ?

Nice work, once again.

That's it I think. At first glance you would think they're been wired for active running, until I opened the box, at least, that's what I thought, but yes it looks like a measurement thing to me.

Are you tempted to paint them.......White? Or any other colour.

They'll be painted for certain, I'm not a fan of them in white. I'm likely going to go for a Porsche flat green with these, black drivers and gold logos, although this changes daily. These ones for me are a lifer, so they'll be very personally done.

=====================

A brief update, as it would be pointless to photograph the same procedure on the other cabinet, however, this one is also now ready for a higher build and grain removal. It's very unfortunate that I'd not stocked up on High build, specifically Upol High #5. The second cab is in a grey high build primer I found at home, I've ordered two more which should get me to the pre stage of a really high build green TI primer.

All 8 corners on this one needed rebuilding.

From my first NS1000M resto, I learned there are a bunch of things I needn't have done. For instance, painstakingly removing all gaskets etc, I don't need to do that as I made new ones for the last set, I'll make new ones for these so I left them in place to protect the wood behind them.

I'll likely be onto the drivers now, considering my lack of primer for the cabinets. 

Thanks,

Carl.

Not entirely sure why I haven't kept this upto date.

These are much further on now, so here are some updates - The cabinets are now in high build primer in the New Forest Classics spray booth.

These will be ready for paint very soon so today I decided to strip down my matching Yamaha CA1000ii to restore the chassis to the same spec, so i'll have a lovely bespoke matching system.

I love everything about this amplifier.

All sorts of updates to come!

I'm loving reading about this resto, Carl, a proper labour of love. Looking forward to seeing the final results!

Amazing work Carl, that amp should make a great partner, I.remember it working well with the JBLs. 👍

So, a few posts ago I mentioned I would strip my Yamaha CA1000ii down for the same cabinet treatment as the speakers. So this was dropped off at the same time, after i’d finished getting the cabinets up to a high build stage. This wasn’t good enough for our painter so he did it again, then flat and paint on top of this. Collection day was a nice day, expensive but nice.

So the first thing I did when I got them back was put the amplifier back together, I didn’t want the amp exposed any longer. I’ve had this amp for years, it’s had an extensive Internal resto and now has a nice pretty cabinet that matches the speakers.

DSC00696

My only extra wish for this amp would be for me to find a silk screen place that would be able to copy the front panel, I would then have it remade and anodised black to match everything else.

Chassis being built back up ready to receive the amplifier -

Then it was time for the slide in, this wasn’t so much fun as it is exposed on all sides.

With this back together, it was time to turn my attention to the drive units. 

Satin black with a slight texture, copper bolts, newly dyed bass drivers etc. 

DSC00732

I’m extremely happy with the colour coded protector on the midrange drivers, these were painted with the cabinets and amplifier. There’s a layer of dust on everything at the moment.

I’ve actually polished these bolts again, you should be able to see the difference with the installed pictures below. 

DSC00875

I rewired the midrange and tweeter with Chord Sarsen cable to run to the back of the speaker, again this will be explained below. Once I rewired them I installed them in the waiting cabinets. It felt nice putting them in as it shows signs of moving forward/getting somewhere. Due to stuff beyond out of our control this build is taking me a long time, it’s the first time i’ve actually just relaxed and let things flow during a speaker resto rather than forcing the pace which has allowed me to hone in on certain details.

So I made all new gaskets and I popped the mids and tweeters in, I’ll deal with the grilles in one hit when I have the bass drivers installed.

And this is us up to speed in terms of pictures.

I’ve rewired the drivers because I’m going to wire them as you would actively, 3 sets of posts on the back of each. That said, I am going to run them passively. My next project is to build my external crossovers, design a box/lid etc to house these and run 3 sets of cables per passive, allowing for active running in the future if I ever want to but benefiting from external crossover that I can take great care over. All of the crossover parts are here, I’ve gone for Troels top design for the NS1000. I’ve ordered all of the terminals which will take a while to get here and will need to CAD design the input/output plates along with the rears of the speakers and lids for the external passives. 

I’m loving this build, the colour is Brewster green, a rare Early 90’s variant that Ferdinand Porsche commissioned for his own 993 Turbo.

More updates soon as they’ve just made the list of “things I need to complete before 2021”....

Carl.

Love the green colour and the finish is absolutely fantastic. Active NS 1000s are a tantalising prospect for the future.

Crossover bits <3

So I've been at it again with some more bits. Since opening the box that arrived with all the new crossover parts in I've been longing to get the binding post assembly together, wire the speakers and then start on the external crossovers and their housings. 

If you remember from the previous page I posted a picture of a set of copper binding posts, these were bloody expensive but I think they're wonderful so I ordered them for the rest of the build, but.. So there's 14 pairs in total, and I thought they came individually so ordered 28, of course, 28 pairs turned up!! Costly screw up, at least there are a few (14 sets, enough to do another complete build) spare... We live and learn.

We finished a project a few days early this week so had a spare day Friday, I asked one of the guys if he'd make up some rear plates for me whilst I worked out the crossover layout, the results are the genuine Alcantara upholstered items below, gaskets were made and they were installed -

50629532086_63a8418782_c.jpg

At the moment, top - middle - bottom represent their respective drivers, I'll likely have this laser etched or have a foil sticker made for the side of the cab to show orientation.

I then started to figure out passive crossover orientation. I'm not a specialist crossover builder so if anyone spots any fundamental errors please feel free to point it out, but don't be a dick about it. I've faced the coils in odd directions to minimise any interference between them but the caps are laid out simply aesthetically.

50628784403_8269c270c2_c.jpg

Now this panel is made, I can start to design the depth of the enclosure that will house the crossover, hopefully I'll be done with that this week so I can get those boxes off for paint to match the speakers. While they're away I'll make up all 8 cables - 2X 3M and 6X1.5M with some lovely braiding and bananas.

Really enjoying this build, it's nice not to have a time frame and just do thing the way I want them done. 

I've a long list I'm yet to do but we'll get there. I'd love them playing records on Christmas day.

The pic of the crossover parts showed air cored and foil inductors Carl ...but the built up crossover has ferrite cored ones ? 
 

Silver Z caps are worth the outlay 😀
