Nice! I also see you have an nCore amp - sweet setup!

Case and Linear supply

Postby royd audio » Wed Jan 09 2019 11:46

So a small update while I wait for some cash monies so I can afford to continue. Nothing earth shattering but prepping for the power supply. I have a split decision, two Linear supplies, slightly customised off the shelf or one bespoke 60VAC supply with split outputs... Decisions, decisions.

In the mean time I'm pre-empting the biblically high Protocase quote for my enclosure with a more compact alternative. A while back a lot of people mentioned they like the old "shoebox" style Naim amps. Soon enough an intrepid entrepreneurial guy on the Pink Fish Audio Forums (I kid you not that's what it's called) stepped up to the challenge, dug into his own pockets and made a perfect reproduction of these cases.

Image
The case is extruded 3.5mm wall aluminium. Powder coated in a two step process to match the original Naim finish perfectly.

Image
The inner sled was made to match the old size Naim amps like Nait 2, and NAC 32.5, 42.5 and NAP 110 etc.

No one bought them, primarily because they are tight old fucks with no idea of how much manufacturing costs in the real world. I managed to use his cases for a few projects and they are fine bits of kit. Sadly he made a loss and didn't make any more but I've got one lying around so I've based my "fall back" design on this.

I'll need to get the inner "sled" replaced and a fascia made. I'm aiming for a Naim NAP 100 kind of look. cutouts on the rear are all there, I just need final marking positions for the supplies when I buy them. I may also add a power LED on the front - in green of course...

I did kick this idea around (pardon the pun). Manufacturing a complete unit would be a compliance and insurance nightmare, but as a kit it might work. Find me 100 more good strong men like you and I'll stick it up on Kickstarter ;)

Adam,

Are you planning a streamer with juts Digital Output or also with Analogue outputs?

Hi John, it's analogue out only as it suits my needs but perhaps there is room on the case for digital out.

What would you pay for a machined case? Would you want the option of adding a Linear supply or have it already included? Do you want to be able to choose a DAC/Pi configuration? Do you want analogue and digital out? Lots of questions, I may start a Poll.

I'll list the BOM and prices at the end of the build when I get there...

Case and Linear supply

Postby royd audio » Fri Jan 11 2019 16:28

So the news from Protocase was that I'd need to sell my firstborn and possibly one if not both of my kidneys to afford it. I had a hunch it was going to be pricey but it was a blow nonetheless. However adversity drives innovation and fortune favours the bold. The new compact layout is complete and I await the cost, hopefully an order of magnitude cheaper as I'm only getting the inner sled and front fascia made, I'm reusing the case from another project.

I debated about putting a power indicator for the supplies on the front, standard HiFi style but it's another machining process on the fascia and it would push up the cost. I quite like a sleek clean look anyway so when my other half suggested I stick them on the rear of the case I thought why not. That way you can see them when you switch it on and they aren't glaring at you all the time. Another idea is to put them on the bottom of the case at the front to get a nice glow underneath. I may explore that at a later time.

The test linear supplies have arrived and they look very well built and engineered. It will be very interesting to hear them perform when I get the enclosure back and can build everything up. In the meantime my erstwhile polymath friend Nigel is cooking up our very own version with his power supply magic.
