Linestage kit

[Darren]

Hi boys,
I'm thinking( just for fun) of building a line input only pre amp for use in my work system. I'd like it to be as transparent as possible and modest in cost.
The kit should be complete in terms of components and a case should be included ( though the case can be simple - it's at work).
I don't care if it's valve or transistor.
Has anybody built anything like this please? Or knows of something they can suggest?
Thanks in advance!
If I build it.... I'll post some images right here by way of thanks.

LDR based pre is IMO the most transparent pre I have ever had. Costs about £15 for the parts, but you have to source them yourself and a transformer (a cheap wallwart is good enough £10) plus you will need a case.

That looks interesting Puffy. Can you please direct me to a site with more details please?

Darren, You can do it all point to point or you can buy a PCB and matched LDR's (or at least you used to be able to) off a guy on Diyaudio. I'll see if I can get you a link.

You could also try Nelson Pass's B1 buffer/pre. PCB can be bought on ebay.

Thanks Puffy - Much appreciated.

Hi Ali,
You aint got a link for that have you? Cant seem to find it.

[Ali Tait]

You're right, none on there at the moment. There was a chap selling on diy audio. Might be worth a look.

Hi Ali,

After having a dig around you can buy these things direct from pass labs DIY:

If you choose to go this route, I'd love to see how you get on. I am DIY'ing to build my own preamp!
