Drive belt noise after compressor installed

[stvgitz]

I just replaced my AC compressor on my classic and it runs nice and quiet, but after 20 minutes of running the car, the drive belt developed a chirpy/rattle noise only when the compressor is not engaged. Also it speeds up with the rpms. It's not terribly loud but definitely noticeable. Since I heard it initially it has not gone away. Is there something obvious making this noise?

P.S. I intended to replace both accumulator and orfice tube, but I could not open any of those fittings. With a pipe wrench and added heat they wouldn't budge. I just left them in thinking it's better not break something that I couldn't find a replacement to. I should be okay right?

Well now I have to know; idler, tensioner or belt?

You probably really should have replaced the accumulator and orifice.

Here's a little info on the accumulator

You really should replace the accumulator and look at the orifice tube, the orifice tube is the main filter in that system and may need changed.
