Hi. I have a Canary Daart DAC and there is a hum like sound and music not playing well. When I checked 5173g regulator i see that it is extremely hot. When I push it with a pen, hum is reduced but bottom of the pen melted because chip is too hot. I couldn't find this chip in my country. Can I use equalivent chip or maybe a better one? Coiltronics coil is also buzzing.I am a bit disappointed because it was an expensive dac and I did not use it much. 5khz square wave also almost same as my cheaper Muse DAC which I added in pictures ( I made a mod and changed the power supply Panasonic FC 1800uf capacitor with 2x 1000uf Nichicon muse capacitor but I do not think it caused a problem) I was happy with the sound before it malfunctioned) Regards

Hi. Yes I am sure polarities are true. The sound was very good after I replaced the capacitor with Nichicon kz. After some months this problem happened ( afaik it happened when I touched the case of dac ,maybe because of static electric discharge)
However I will try your suggestion

This too rings a bell for an (unwanted) make and break contact.When I push it with a pen, hum is reduced
