Not much to see other than its the usual 50/60 Hz AC output transformer. At this point probably just send it back for another one or a refund, but still not likely to get an answer as to what failed which is somewhat unsatisfying. At least it didn't take anything out with it, but the fact that things cycled off when it went bang means it was a substantial failure, but that could also be due to the iron-core transformer in the wall wart saturating from excessive power draw by the amp.I taked photos (L30 itself, power brick and RCA cable) in order to fullfill the petition of HiFiGO, but it's irrelevant since I haven't opened it to avoid problems with the warranty and everything is perfectly on the outside, so little interesting to see.
But, these budget amps are sometimes light on the design. I know my Schiit Magni Heresy caused all kinds of RF issues. Turning it on would cause my monitor to just turn off from the switch contacts closing and arcing. Had to add a snubber to stop the switch from sending RF spikes back into the power strip, not to mention decoupling so I didn't have to listen to digital noise and other junk in the audio. Oh, and the relay is fake AF since it has no DC offset compensation. No servo loop to settle or capacitors to charge. It just pisses away 10 seconds of my life each time I turn it on. Almost nuked a set of headphones the first time I used it.
