  Hello, I made a quad Amek 2500 mic preamps rack, so here is the layout if some of you want to etch some single side PCBs :

Hello, you can find the schematic on gyraf website's for instance : http://www.gyraf.dk/schematics/Amek_2500_micamp.gif
And the output stage is published on the webpage.
I don't think I will put samples but t's a quite renowned preamp and you can find opinions about it if you make a search..

Very nice!!

We will need to know board dimensions in order to be sure to print it out to correct scale (more than 5% err makes it difficult to mount DIL ic's)

For sound examples, I think we got the 2500 for recording Steel Pulse's  "True Democracy" album: https://youtu.be/8nKLfruvxsE

The file on the website is at the true dimensions (106,93 x 57,4mm   /  300px/inch).
The drawing is quite basic, you can add a bit of blank space at the back or on the sides to add mounting holes. I think I added two mounting holes at the back, so the boards hold between them and the pots.
