got mine as well last week and boards look great!  thanks bruno2000!

btw, i was looking over the schematic and noticed that there are some circuit variances from the 1038 channel amp schem i have.
i know there are some biasing resistor value changes due to the dual supply configuration you've utilized for this project vs. the single rail supply in the original, but wondering about the other configuration and value changes? i've only had a chance to look at the first couple of input stages so i may not be looking at the 'whole picture' here, but still wondering.  are these changes based on another schematic or actual channel you've seen?

thanks!

My "strip" is based on the 2038.  That's what I had to compare to.

There is an updated BOM for this project, fixing some typos, and adding some Mouser part numbers.  PM for details.
Thanks!

Here are my new babies... Still waiting for the 2U enclosure. Separate +24 VDC on relays. Can't wait to listen to those...
A good twenty some hours of soldering. I still need to decide on an external or internal power supply.

Modules all racked up. I used a separate power supply in an ammo can (as suggested by Bruno2000). Will upload some samples soon...

OK, I've gotten good enough winding the inductors to make some for other folks.  If you'd like some, please PM me and we'll talk.
Thanks!

The PCB is $60, and the inductors are $45 / set of 2.

Very cool - will send a PM about some inductors.
