Threshold NS10 Lineamp PCB

[apassgear]

Fast as a gazelle Manu, and now you speak universality… excellent work. Guess we can install there most of Colin’s and Jacco’s suggestions.

Thanks to all helping iron out this issue... better than expected.

Manu sez the board is 72mm long.

Chute, with Antonio present i can't say Tan Theta, that's highly uncivilised.
That's just as rude as saying Tetas Grande,...or Grande Tettone with someone from Italy active on this thread.

Besides, look at my avatar, i'm the sleazebag, not you.
Nanananananaaaaaah.

LOL

 

[apassgear]

you could also add spacing for a 'lytic either Elna Silmic II or Black Gate, or something like Vishay/OS-CON...

Not saying that is my preffered option there but still retaining a 5mm spacing so I think most any lytic could be installed. I might do some testing for lytics when time is available and report my opinion, most sure you will be the first here thou.

Cheers

Thanks to Jaccolinas Tettone Grande the board is now 41x72 milimetrov

Still Piccolo enough

 

[apassgear]

Great Idea and highly faisable ...

Thitta ? Unfair... as I can not even write bon appétit without beeing censured

Gee Manu, LOL... I caught it a bit late

pcb v4.3

Manu,
The pads of R111, Z and VR115 are very close - suggest off set components slightly.
Nice tracking between Q105,106 and Q101, 102 - a via instead for R107?
Can add extra capacitors externally, on the o/p terminal block

 

[Manu]

Hi,
Thanks for hints ...
Better now?

Wiki

Nice job!!!!!
Thanks for sharing all your work guys!
I am trying to edit the wiki, can anyone help me? I would like to order 1 NS10 (stereo) and 2 shunt reg pcb's.
Thanks!

Looking good.

I may be able to squeeze the Jantzen PPs on this.

Is that FB a specific component or just "a Bead on a wire loop"?

FB is a plain ferritbead on a loop, as you say.

I think there is just room for a 4,7uF Rifa PHE426 at the output now. I will try those shortly and I think they will be good at that possition. The PHE426's are very low ESR caps.

or something like OS-CON

I thought you were still sitting an a pile of KP1837 ?
Graph on page 599 : DF
Os-Con has a low DF compared to other lytics.

Nice volume. Thanks for the link. Nearly 1000 pages

This is my desk at work, on the way out for the weekend

Good News, NS10 group buy

I have good news from Nelson regarding NS10 saying “No problems with group buys” which I interpret as go ahead with the GB.

Got no answer from Threshold, I think they don’t care much about a small GB on an “outdated design” that most probably will never be produced again.

So, from my point of view this Classic preamp can be reborn as a Clone with updated components and “shunt regulators” to the joy of DIY builders.

On the Wiki I see many saying “2” for the PCB I interpret that they want a couple of boards for a stereo. As I said before, the boards will have two PCB’s, scored for separation, so on the Wiki please express 1 for a stereo set.

Cheers

For your enjoyment only, run across a piccy of a dissected metal and foil cap.
Try that with a metalised foil.

Since there have been a few questions about other voltages, here is a version for 3.3v output. Load is drawing 50mA, input CCS is sourcing 83mA. It looks to be able to function on as little as 5v.

That sounds great, Tony. The wiki says 232 Toole-boards at this point Better check the digits though. Usually someone forget about adding to the total.
Tony, I had an idea for the raw supply. I will mail you about it shortly.




Edit. Colin, thanks for the plot. You posted while I was typing
