Some of the 41Hz website content is available here as well:
https://web.archive.org/web/20111031111101/http://www.41hz.com/forums/content.php?239
Sadly there is no archive of the forums.

When I backed up the site with the Firefox scrapbook plugin, it only went to a depth of 3 links and much of the forum content was 4 links from the sitemap page I started on.
So I have a list of postings, but no content for many of the different sub-forums:

I seem to post this question about once a year, not sure if I've asked anyone on this list...

Does anyone have Assembly Instructions for the AMP10 (regular Amp10, not the Basic version)?

Maybe Havoc or Scratchy?

I emailed V-Bro a few years ago and he said he had all AI for all 41hz amps but I wasn't ever able to get them from him.

Here you go:
AMP2 - Google Drive
The spreadsheet has multiple tabs. One for calculating resistors based on input values.
Another tab has a spot to tape the SMT tape to each row, with locations for each component. Just print the sheet and stick the SMT tape to each row.
I've also included all the datasheets I could find for this amp.

Does anyone have instructions and schematics for the original AMP9? I built it some years ago and shelved it. Lost all documentation and instructions for it. I would appreciate it very much is anyone can share anything on it. I have figured out the basics to get it operational but there are some extras that I want to know what they are for. It seems like they are not used? Particularly U3, U4 and U5.

Thanks in advance.

Does anybody have the assembly instructions for the AMP10 Basic? I have one but it shorted and I'm trying to sort it out. I have most of the info, but really need the layout showing component names and locations.

Thanks in advance.

Take care,
Peter

Looking for PSU1-VR kit assembly instructions

Hi, I found an old PSU1-VR kit from 41hz but no instructions. There are a number of very small smd components that I am not sure where to place. Desperate for the assembly or even schematics. Help??
