Default Threshold NS10 mods

Hello everybody,

be kind with me, it's my first post in the "Pass Labs" forum, I've always been a thermionic man

Anyway, I have a friend who has a Threshold NS10, and since he isn't signed up here, he asked me to post his question.

He would like to know if there are any useful mods to the circuit. I wouldn't think so, since I admire Nelson Pass circuits, and I think there isn't room for mods (since the designer may have already optimized the circuit).

He heard about a mod in the power supply, or something: he already has replaced ALL the electrolytic capacitor with Elna Cerafine, and replaced the input and output connectors.

I searched and found this:
Threshold NS10

So, does someone has any idea, or do you think the project is already perfect in itself.

Thank you very much in advance.

let your friend do what Papa sez;
for further info (fun ,amusing ...) look in few threads about NS10;
possible improvement can be implementation of shunt reg in PS,but that demands other xformer (probably in dedicated case,with umbilical)
and few other things;
let us know what your friend decided..
btw-almost to forget,NS10 is crappy piece of history,nothing more;
I can arrange local pick-up,and I'll do proper disposal operation.....

Sorry people,

I made a bad mistake.

His preamp is the SL10, not the NS10.

If a moderator is reading, could you edit the title of the thread? I cannot edit the first post any more.

Excuse me

Hello dear friend,

could you give me more details? I can't see any regulator in the schematic you attached.

that's presumably origigi schematic ; in lower part you can see 7815 and 7915 regs

constructing nice shunt reg (meaning 317 and 337 as series main regs,then locally placed CCS + shunt reg for each stage) is little complex task without exact gadget in front of me
I need some data ,especially current consumption for each stage

Ah, I understand.

Thank you very much: since my friend is good with the soldering iron, but not quite good in electronics, I assume he cannot properly measure consumption and set up a regulator.

Maybe I will ask to send me the preamp and I'll manage that.

Thank you all very much!
