I have some of these guys on order, but barebones versions.

http://www.lazpro.com/buy.htm

Wondering if anyone has a parts list or any other info for these projects so i can start ordering/sourcing and just checking out things.

I'm just getting into DIY and am working on a gssl at the moment, and there is MORE than enough threads that have helped me out with it, just searching for more info on these particular goodies.

Cheers
 
Let me get some stuff together for the EQ, the 525 is pretty much been well documented.

I did have to import the small push button and switch caps, but I think I know where to get them in the states, that is if your in the states..

You may want to point out what you did get from Peter, and what you need help with

 
Ah, I'm from Canada "eh"...
I'll update my profile for ya.  Thanks for the help.  All that is shipping to me is metalwork and pcb's for the eqa and 525....yes, a friend of mine is doing the 525 so I can pick his brain, but I'm in need of the EQA info!

Off topic:

I'd like to learn something about these push-switches: Who's the manufacturer? I'm really annoyed in searching for these for ages... In my Soundcraft-Mixer there are 2x, 4x and 6x-switches in this shape. The 2U and 4U I got from ALPS for acceptable price, after long research (Price-range was from 3,50 Euros to 0,25 Euros :(). But ALPS don't make any of the 6U-switches... :-\ O.K. but C&K do them (PHA-series). But I couldnt find a source for these for under 1,80 Euros, and for 50 switches I find that a bit way too much. So, who makes these grey switches in that pic? Please!

thanks

Skinny,
The eqa has part values marked on the board, although there are a couple of changes to be made.
I'll squirt over the details when I've gathered them.

Hey, just thought I'd jump in.  I'm nearing completion on a pair of these, but am having troubles finding rotary pots with the appropriate pin spacing.  Anyone care to share their U.S. - available part of choice? or if you know the dimensions, I've looked and looked but couldn't seem to find it anywhere in the original build thread. 

thanks,
ben
 
You're talking about the 525, right?
