Up visionline genset switcher sound issue.

That seems really loud. The Gensets do emit a hum type noise when just sitting powered up, but mine are not that annoying. A friend had the NS Genset for a short time and returned it because of the hum.

Yes I had not used this engine for a long while. I took it off the shelf to add it to my dcs remote and thats when I noticed the loud hum. I do not recall it doing this before. This engine needs a new smoke unit controll board so untill I get the part I can wait to open it up. Just was courios as to the hum and what to look for here.

I notice the RS6 board used in the VL Genset does have a hum.  It's not loud, but it's certainly there.

Any fix for this?

None that I'm aware of.

thanks john

I have one and it has the hum. I did notice it was louder when I was using a mth Z1000 transformer. Now I use a PH 180 and it’s not as loud but it’s still there. 

It's the chopped waveform getting through, not sure what could be done with it.

My VL UP Genset has always had this issue and I eventually resigned myself to thinking that it would sit on a powered track just saying, "I'm an O gauge electric train!" On the plus side the slow speed performance and smoke/light features of this model more than make up for a slight background buzz.

But the OP's background noise is a lot louder than mine. I had another VL engine (ATSF 3000) that had about that level of noise and other issues. Finally had to send it to Alex M. for service and he found that there was an issue with a board that was overheating. Even after repair, however, the engine still has a background buzz that is common in Legacy models of this vintage.

I am not sure how the waveform affects this; with the Genset I have had the same issue using either a Z4000 or a ZW-L.
