Glad to find this, my ADA MP1 Classic is now making crackling noise. It's time to change some caps. Suwun nggih mas videonya 🙏🙏🙏

[@andrewraharjo]

Crackling noise biasanya kasih Dexoit beres mas e. Good luck

[@aliefjauhari]

@@andrewraharjo crackling nya bukan dipotensio output, tapi muncul hilang timbul disound dan powernya melemah. Barusan udah tak ganti caps yg 10uf 350 krn kelihatan rada cembung permukaan atasnya, dab kbetulan masih ada stock yg value segitu. Crackling nya hilang, tapi kualitas di low nya masih ada kesan sember kalau dipetik agak kenceng. Kelihatannya 4 caps yg lain harus tetap diganti juga ya mas?

I have the same ada classic and the issue is that over time one channel gets squizzed and crunchy sound. Happens only for one channel and when the device works for some time. What could it be?

[@andrewraharjo]

That is super weird. I will suggest to start looking at your voltage rails first. Make sure you get the correct voltages

[@habarpozitivfoto8430]

so the issue was the leaked capacitor?

[@andrewraharjo]

Yes, it was bulging filter cap and caused issue with voltage rails. Simple fix
