than it makes no difference how the box is placed. Is that your point?
It makes no difference to the transformer, no. The transformer will hum the same in any orientation. But, that transformer is attached to the case. I can’t guarantee that in different orientations the case would not resonate more or less. If the transformer has NO hum, then there’s nothing to transmit. If the transformer has a little hum, it is possible some orientation would sound louder than another because either the surface that is coupled to the transformer is now pointed at your listening location, or that the coupling is better to the case somehow due to stresses placed on it. |
@erik_squires Apparently I didn't understand your 1st post. Your last one says,
The reason a transformer hums has to do with the quality of the AC, and it's internal construction.

none taken. Too often people ask for help from those who do not have a vested interest in the outcome, which is why I directed you to the source

Hey OP, The reason a transformer hums has to do with the quality of the AC, and it's internal construction. DC on the line, caused by too much draw from the positive or negative AC power is the usual suspect, as are manufacturing deficiencies in construction. You can read about this in much more detail here: https://testguy.net/content/259-Transformer-Humming-Noise-ExplainedBut the point is, the orientation of the transformer in regards to the earth is not what causes it, nor is the chasis design. Mechanical hum is a matter of the transformer, and incoming power. Now, it is certainly possible that hum may be louder in one orientation than another. :) |
@erik_squires Can you elaborate about the laminations? @millercarbon I'm concerned that the heavy transformer will vibrate. I suspect they have ssome kind of damping to keep vibrationat a minimum when resting on its botttom. But what happens when that weight is suspended from the cabinet. Then too, IIUC, Eric is saying that the lamination may be problematic @tweak1 I have talked to Wally. he says it should work. But I suspect this is as much guess as anything. No disrespect meant. @testpilot
If it can survive shipping where it is violently thrown around, it will survive being gently placed on its side.
May be the best answer yet. |
This can be a real problem check it out. |
I recommend you contact the manufacturer, or in this case Underwood HiFi

Don’t think it matters. Keep cords separated, and hear for electrical issues
mess w cords, rca’s, power cords, CD player,
I use a Furman line conditioner, and a monster me in 2nd system, monster one is poor quality, tweeter static, etc!
mess w it til u get the sound u want!
replacemcords, rca’s, from CD player, preamp, amps, etc!
Tinkering is key |
concerned about the transformer weight causing problems.
Such as? |
Will that stress cause the transformer to buzz or hum?
No, this has to do with the laminations of the transformer itself as well as the incoming power, now how it rests. Now, if it IS already vibrating and you tweak the cabinet so it's more resonant, that's' another story. |
I would be careful, as the product designer probably didn’t think of that. :)
Thanks @erik_ This was my thinking also. Obviously there is more stress on the cabinet. Will that stress cause the transformer to buzz or hum? Probably one of those unknowable's isn't it? |
Normally this is fine, but if you have a large transformer inside I would be careful, as the product designer probably didn’t think of that. :)
The only real issue is where is the transformer bolted to and will the sides or front properly handle the stresses.
Best,
