Cheap 10V source(LTZ 1000A) based on reference designs.

[TristanK]

Hey,
i wonna build my own 10V reference source. My goals for the start is just working and cheap. i want to improve is in future revisions.
It would be very help full if someone could overwatch my plans and give me a feed back.

thx to all of you

The LTZ1000A on it's own is not a cheap solution. It makes little sense to skimp on the OP-amps. The suggested LF412 is not working as it is not single supply.
A cheap solution for a 1 st test would be more like an LM399.

Much of the circuit is hard to read, but looks like the standard circuit - at least it should be.
The trim of the resistive divder dowes not look good, with too much effect of the trimmer. The feedmach is also from wrong side of the inductors.
The choice of the OP-amp for the output stage is way off.

Q2 collector is connected to ground and wont work that way. I assume you want to use it as a driver, like done in the Datron schematic?:

Suggest also this design as a reference:

Here's my opinion:
Don't re invent the wheel.
Just take any of the many improved circuits in the big thread, chose the cheapest design, components and PCB, plus a suitable case, best is a double shield design, and just assemble the whole stuff.  Have a look, how I realised the whole assembly, with either the bare reference, or an additional 10V output as well.
The circuit based on Andreas add-ons seems to be the most suitable.
A low noise stabiliser and supply is also required.
You did not say, what's your basic intent, I.e. tinkering only, or just creating a stable reference, so that would determine your proceedings.
