Oxy-acetylene Regulator Making Noise?

The welding shop I talked to when mine went told me that the rarely rebuild them because of the liabilities involved with the high pressure and they'd be happy to sell me a new one for $200.. here's a link to a new one: http://www.ebay.com/...=item5649f2ad97
The shop that we get our supply's from every week rebuilds 15 to 30 regulators every week. If you can find a good welding supply shop, they can fix you up fairly inexpensively, or sell you a rebuilt one out of their stock. Our shop aways has a few that they rebuilt and don't get picked up, they will usually sell them for the repair bill.

My regs make a little noise once in a while, and more often than not I have them set too high. Tends to send the diaprams into a a flurry , but then again, I generally have a rosebud on the thing...

The last time I used my torches the oxygen line pressure gauge would make a strange humming noise and the needle would vibrate. I figured it was just a bad gauge, since it had to be replaced anyway. Today I got a new gauge and I wanted to test it out. It is worse then before! While I had the gauge off to take to the welding supply store I put a piece of tape over it so it would stay clean, so no dust got in it. What do you guys think the problem is? Maybe I will just oil the the regulator...
This one is SIMPLE.
The condition is called singing.
It's fairly common in O2 regulators when the torch is overdrawing the regulators ability to deliver, especially with cutting heads..
The diaphram is slapping the needle valve open and closed so quickly it produces a song.
It can also occur in extreme cold conditions especially with cheap regulators.
You either need a smaller torch or a larger capacity regulator.
