I notice that PS1 units all seem to have a buzzing in the background. However some units it is louder then others. Is there any significance to such ?

I notice a little buzzing in the sound when i first power it up but it is charging my BCR after a minute it quiets down. nothing to worry about. I've never had a issue from the temporary noise which pretty much goes away after a minute or so!

I don't use bcr's
Buzz I mention is heard only at some stages of idle operation. While it may still be there, only certain stages are more noticeable.
All units seem to have such, but as mentioned some units are much more louder.
Now the louder the volume is turned up the more it is drowned out. But at lower volumes it is much more noticeable.
Caps going bad on the boards can cause buzzing at low track voltages.
Good to know. But low voltage does not change this paticular buzz.
Yes this buzz is most noticeable upon start up. After sounds kick in it is pretty much drowned out by such. However if you listen for it you can still hear that it is still there. Then only hearing it at the few times little sound is being made or announced.
Needless to say, some units seem to have a more louder of this buzz. I was just wondering that for the ones that this is more noticeable if by any chance that may mean that something is not quite right, on its way out ect.
For instance I was thinking, perhaps something was wrong with the speaker.
I know that I have heard of speakers causing issues. Not sure what that may be. Which is why I thought I would ask..
You will get a lot more buzz sound at start-up with an electronic transformer (ie CW 80) vs. a standard transformer (ie 1033).
Speakers usually cause distortion or intermittent sound when they are about to die, but they don't add an additional sound, like buzzing. The buzzing is likely coming from inside the sound system. Most likely a component failing and getting flaky as it fails.
It won't hurt anything to replace the speaker and if that eases your mind, then go for it. be sure to match the impedance of the new speaker with the old speaker.
I use mth 75 & 100 watt transformers.
Borrow or try a standard transformer and see if there is any difference.
It's an electrical noise, and will always be there. When it's due to something going bad, you'll know because it'll be louder than the sounds. I had this happen once and replaced the bottom board to fix it. It was awful.
