Fairly common. I have a different Astron linear supply and have had that issue. Make sure the cabinet and transformer screws are tight. Assuming there's a relatively small gap between the top of the transformer and the top of the case, stick something between the two surfaces (folded piece of paper, for example) to dampen the induced vibration.
Barry W2UP Does anyone have a way to dampen the physical hum generated by the transformer in an RS-35M PS? This really is just transformer hum I’m hearing, not signal hum…my station is fully bonded and as a result quiet in that regard. Most folks probably never hear this hum, but I have been “blessed” with really good hearing and so this hum irritates the dickens out of me. If push comes to shove, I will relocated the PS farther away from the operating position, I just didn’t want to have to extend power and bonding runs and thus am hoping someone has a different idea.
