Bitmain has been offering this same type of training for over a year now, so saying they arent concerned really isnt true :/ They are doing things at 10x the scale of everyone else and the company has been suffering growing pains. For example they were out of space in their Beijing offices before the building was even finished due to the rapid expansion of the company.

I guess there's just been less documentation of Bitmain having some sort of repair training program, I haven't even heard of something like that until now. Is there any information about Bitmain's program out there somewhere? I've never been great with the technical details of miner repair and I happen to be travelling to China this summer (specifically Nanchang and Beijing), I'd be glad to take a detour to Bitmain or Avalon's facility to see how things work.

I didn't do a full scale disassembly for the A761 unit, but my understanding is that the control board,
PMU board, hash board design etc. is similar to the A741, but there are more A3212 chips in the A761
and it has a built-in power supply unit with thick wires connected directly from the PSU to the PMU boards.
And steel tube case design is ofc different compared to the A741.

Thanks for the info, I guess they used the 761 to help develop the 841 or something of the sort. Weird they never seemed to release it to the Western market, I recall seeing an article back near December saying they were only releasing it for Asian markets.
