I'll have to go with the Meanwell PS, as the Micro Audio PS will not physically fit. I've thoroughly tested it on 3E's board and it sounds wonderful. I'll clearance the inner alloy plate for cooling ducts.
Sorry if I missed the info, but what do RL3,4, and 5 represent on the bottom diagram?
I'll be doing base plate programming and machining today. Dont want to miss anything.
Got my IEC socket and power button in also and will machine case to make that scenario meld.
Had to re-drill the thru holes for bigger insulated binding posts inserts on this case...

You didn’t miss anything - I am not quite sure what RLx stands for either. That was from the PCB layout software. I think it might be distance from edge of metal traces. I’ll ask. But if all you need is distance for the screw holes. They are positively 112.0mm x 120.0mm CTC corners on a square. Thread for M3 brass standoffs.
Here is a drawing from a production amplifier baseplate so I know that the 112mm is correct. The board itself is 120mm square with rounded corners.
10-4. Had to be sure as the base plate will accommodate either your PCB or 3E's. Finalizing this design with the smps mounted in seperate upper chamber as well..
I’m starting an interest list for anyone looking for one of the version2 TPA3255 bare PCBs with PFFB capability.
These will be 2mm thick, 2oz copper, ENIG finish with green solder mask.
Please add your name and qnty here. If I can get 10 units interest I’ll place an order for another batch.
Price will be $32ea.

The input goes to a 100k resistor load to ground. This is for each input A, B, C, and D. You can change this value to 47k etc if you want.
Typically, $20 to $25 shipping to most countries outside CONUS.
TPA3255 bare PCB rev2 (with PFFB option). These will be 2mm thick, 2oz copper, ENIG finish with green solder mask.
Group Buy Interest List - $32 each
We need 10 units to start production

Am sorry, my question must have been answered before, but am I right in believing that each board will give me two channels of amplifier, each capable of about 100W into 8 Ohms? (I know the chip has four channels, but the popular config seems to be to join pairs of channels, thus giving two channels.)
