This PS is out of an Ultra that I have another topic on. The machine has a loud buzz humm coming out of the speaker & most always it"s the noise filter & usually goes away when the filter is removed or at least with my red dot power supplies. This power supply in this machine is diiferent & the noise filter is soldered on a board unllike the easy cutting of the 2 wire & eliminating the noise filter on a red or green dot PS. I took the board out to jump the noise filter solder joints, but there are 5 connection not 2 on each side like the ones for the older PS. My question is how do I jump the traces to elimate the filter? There is 1 2 & straight across are 3 & 4 which I assume you jump staright across. My issue is there is a fifth solder for LOAD inbetween 3 & 4 & I don't know which point to attach it to correctly to eliminate the filter & I want to do it correctly without taking any chances messing the PS up? Any help would be appreciated
Thanks,
Dan

That is NOT an Ultra Series power supply! At least not from the U.S.
Looks like a poker power supply or maybe overseas 240v power supply??
I'll check it out.

If you have a lot of noise then maybe the filter caps need to be replaced.

This machine is making the exact same Humm that the red & green dot PS cause that I've had and removing the noise filter always seems to work and is the easiest for a 1st step. I just don't understand the 5th joint for the load on this filter to bypass it. Hopefully someone will know

Here are pics of the power supply inner & out & also a pic of the filter showing the 5 point connection diagram on the label. Need to know what to connect the 5th connection to LOAD when I remove the filter?
Thanks

I have one of those little PS boards. (BUZZ gave it to me!)
Looks like left side is LINE #1 & #2, right side is LOAD #3 & #4, and the middle right looks like a ground with a ground symbol.
