G7 - Parts...

[BackHand]

Hi guys!

I've tryed not to write on the forum and searched all I can..but I'm a newbie.....so I still have some questions regarding parts for the G7 microphone... Rolling Eyes
Maybe you pro's out there could help me :razz: !?

I've got three Iaudio bodys and Dale's M7 capsules..so that part has been taken care of...and the Lundahl I'll manage (I live in sweden so maybe it's a little bit easier for me !

Now I'm going to order the rest of everything..allt the stuff for the PCB's and the Tubes..and I've tryed to follow your "Components List" but I've stumbeled over some questions...
My goal is to buy only the best components to make thess microphones as good as they can get...the only thing that I'm trying not to spend a stupid amount of money on is the tubes since I've read that they don't really effect the sound so much in your G7 design?

I'm doing an order for all of this at RS Online (http://www.rsonline.com) since I've read that they have everything an so forth..to make it easy..

If you could please check this list for components and maybe come with suggestions of changes (maybe with part numbers from their site?) I would be more than thankfull Heck Yeah!
I don't know anything about watts for the parts or what kind to choose and so forth..only guessed and tryed to folow your list..

This is what I got to this far:

659-832 - Diode,Bridge Rectifier,W049

Any suggestions for what EF86 tube to use that is not to expensive and still good enough for the rest of the components?


Thanks a lot !

None one :sad: ... :?:

sorry i have no suggestions for you. i'm located in the us and i'm also working on a g7. sourcing the parts seems to be very time consuming. i'm using a pcb(gustav) and have all the parts ready to go. when the mic is assembled and working i am planning on posting a parts list with sources and catalog numbers. this will only be good for those in north america however. when you get your mic up and running could you pm your list to me or post it in the same thread. this way there will be one location(thread) where someone can easily source the parts for this project in both north america and europe.

I second that...

I'm also in the process of building a G7. I'd estimate I'm 70% finished. I ordered my capsules and tubes yesterday, and I have to box up my PSU (which I tested). I don't want to post anything prematurely and it be wrong. I will have a complete parts list as well once I'm complete.

Check the cables I listed in the Black Market Ebay section.
