Will a 36V-6 Amp SMPS suffice for this 3255 unit? Also, hopefully I receive the version with the 12V accessory supply so I can wire in a separate 12V LED power indicator.
depend on your speaker impedance and rate power, but for normal in house use it is good to go
please note that there is slightly tolerance on 36V, adjust to 37V-38V may need depend on board to board.

Thank you. While I'm waiting, what are the size of machine screws needed for attachment of the machined heat spreader?
Thank you for the quick replies. The unit landed yesterday and I started mock-up.
One last important question is... did you design the heat spreader to be electrically isolated from the enclosure it attaches to?

I've got some more case work to do next week, so I set the unit up on the main rig this evening for a test run.
All I can say is I'll be selling the modded Ayima A07, this is a solid step up. Dynamics, soundstage, clarity and detail improvements are undeniable. Great job designing this board.

Can i post to ask fosi audio za3 in mono mode? Any comment about this TPA3255 amps in mono mode about SQ.
Hi everyone,
I need help configuring my TPA3255 amplifier from BLT to PBLT mode. I can see which pads need to be connected, but I’m not sure about the correct order of connections. I’ve attached a photo of my board. Could someone please clarify or even draw out the connections for me?
Thanks in advance!

This is usually described in the manual. Have you tried to download it from:

Hello 3e Audio, do you plan to have the A7 with or without a power supply in stock for sale in the near future?
I tested the completed unit on all 4 of my rigs the past few weeks. Have to report that my 3E unit plays for hours high output, without getting hot or loosing sound quality. I believe the machined bottom heat spreader alloy is a better implementation than top-mounted chip design with fins. Using 48v 10A SMPS delivers the goods.
