AMTech in mangga dua mall? You sure that's a 'real' Aune distributors? Because it doesn't show up in the official distributor list:

Might be just a store buying Aune in bulk, and selling them in Indonesia. Might be, though, not sure if that's the case.
For comparison, 'don't blame your ears', based in Bandung and store in Plaza Semanggi is listed in Hifiman's official dealer list:

That's the amp PCB board. The DAC is still usable if you got another amp working. Just plug the other amp to the back RCA out jacks. I experienced that myself. Fried the amp PCB board when trying to do cap mod. Naturally I couldn't claim the warranty, because it's unofficial modding. Ordered replacement(s) from them, but while waiting for it to arrive, I plugged another amp to the back RCA jacks.
Judging from the picture, they won't try to repair it. Too much effort anyway. If they agree to the warranty (which they should), they'd just send you a replacement PCB board.
BTW, if that AMTech is a 'real' dealer, you should push them to replace the whole stuff, 1 to 1 replacement. Technically, their obligation is to replace only that fried PCB board, but since they don't have them in stock, try push them to give you a new whole unit, while you give them your whole old unit, naturally. If they give an excuse that they'd have to replace the PCB, and order it from China (and bla bla bla), just say, 'how about I give you my old one, you give me a new one, and you can sort things out with the main office (China's Aune) later, at your own time and convenience'
In my own experience, they (the Aune base in China) is very responsive in communication by e-mails. Candy was also the one handling my inquiries at the time. Often, she (assuming it's a girl) would reply my e-mails within the same day.
