So I am working on the +24V half of this power supply (TDK Lambda VA-26936) and it works! Yeah!!!
One problem remains, it's making a buzzing/sizzling noise that is pretty pronounced. It SOUNDS like it's coming from the AC input section, but I can't seem to pin it down.
In trying to get rid of this noise I have replaced three of the coils (L1, L2, L3), ALL of the electrolytic caps (even though most were good), and C5. I even replaced the bridge rectifier (D1). This is driving me nuts!
Anyone else have any experience with this? Any help would be appreciated.
Thank You!!
