LKA has the grounding done correctly. Pin 1 goes to chassis along with the RF filter. The chassis loop breaker is providing the ground reference for the amplifier and converter, not pin 1. We did the same with our THAT 1206 converter. No need to worry how the source is connected when done this way normally. As an added twist some sources are now being wired incorrectly and the pin 1 to chassis connection at the amp is causing the source to hum.
if anyone is interested here are the gerbers

I have a question about the EF3-4 board. I know you can use it with only 3 pair, but can the board be trimmed down to fit a 300mm deep chassis if run with only 3 pairs? I ask because I am on the fence about my chassis size and my goals for this build.
Is there a cutoff date for the first group buy? I put in for EF3-4, but may opt for the EF3-3 or a pair of each if the boards cannot be trimmed.
TIA

Unfortunately in your case the EF3-4 board can not be trimmed down to suit the EF3-3 footprint.
I will give everyone enough notice as the cut off date nears.
At this stage if everything goes as planned with Thimios's test of the EF3-4 I would say you still have approximately 3 weeks before the cut of date.
The first production batch of boards is now complete and is awaiting shipping to Thimios.
I also want to design my own PCB - this is for me the most pleasant stage of the DIY process.
Unfortunately, I'm still waiting for the final schematic to be published.
Doesn't look like it's gonna ever happen... It's gonna be 1 year anniversary of this thread very soon..

Nikos, don't hold your breathe.
Minek123, from what I have seen and read you have more than enough information to start the design process for your own pcb design. Do not fab until you are certain that it is correct. Don't fool yourself everyone, it is a lot of work to get a pcb to work right, first rev. Anyone who does deserves a gold star

Τhank you for caring about my health, your kindness .... unless you imply something else but I find it difficult to understand because English is not my mother spoken language..
Hi Nikos,
The Titan 2000 design uses a different shape of heatsink and was designed for use with forced cooling (fans)
The layout of the Wolverine EF3-4 is more suitable for passive cooling (no fans) and the distance between devices will actually help distribute the heat evenly across the heatsink.
Hope this helps

Υes my friend of course and your explanation helps
I would just like a board with 4 pairs to be more compact only that.....
Some pcs 2005-2006 now this amp does not exist anymore....all by hands pcb....

Yes I remember reading the magazine at the time.
Quite good performance at relatively high power.
"Don't hold your breathe" is an English expression that insinuates what you are waiting for may never come; or that your wait for it will be very long.
I can't think of a Greek equivalent (my Dad is a Greek, born and raised) though I'm sure there are plenty : )
