META - Green Pre
« on: January 25, 2005, 04:33:11 PM »
I think this meta-thread has been along way coming and I've taken it upon myself to kick it off. I hope you find it useful. This is not the definitive guide and you are welcome to add or suggest further links and I will update them.

Since there have been quite a few versions of the Green Pre I've tried my best to describe which one is being referred to in the posts below, but I'm sure a lot can be learned from the previous designs as well.

Peter has finished V14 is shipping the PCB.

Matt,

The link for buying Green PCB's is dead, maybe a link or something about emailing Peter to buy the PCB's?

Dear Peter,

The links to buying a kit do not work.  Any link available?  I am growing interested in this project because I am looking to build such a preamp.

Thanks guys,

Have a good read of the 'All things Green' thread, this will give you all the details you need and a lot more!

The 'a lot more' part usually comes in handy, come debugging time. Reading is what all of us spend 75% of our time doing. RESEARCH...get used to it.

I see, but I had a simple question in my mind: Does the Green Pre as default come with high pass filter?
Now, should I really have to go through forum-threads, I don't know how many pages, to maybe find the answer to that question?
Not to mention that half of those links are dead.
Or maybe that's a wrong way of thinking about DIY pres and HPF. But, that's part of what newbies does, asking wrong questions.
How helpful do I really find the answer: "It's on the www -just read it all".
Sorry, just a little frustrated.

The V14 Green has a gentle HPF (12db/octave or so), also Phase switch & Phantom. Also has a 4 LED meter, no transformer balancing on the ins or outs.

Switched gain control and it does not need a pad.

You know what? That really answered most of my questions regarding the green pre :) :)
(..made me having a few other questions though, but, I'll see if I can find out myself.)
Thanks!

I need help finding a BOM for the Green Pre (V14)!

I ordered a stereo pair and the info on the part numbers from Mouser are scattered all over the place... Does anyone have a list of order/part numbers from Mouser?! I want to be able to get most everything from one place...

Also, I was wondering what ya'll think about using a Cinemag CMOQ-2S Output Tranny (CMOQ-2H 600:600 all or mostly nickel)???? I need all the help I can get, first time I've sourced parts and I'd rather do it right the first time than have to buy parts twice... Thanks in advance! :-D
