Strange Loud Popping Sounds

Hi,
I recently bought a Primare i32 amp from a seller on A-gon and am experiencing a problem when spinning vinyl through it.
I hear loud pops while playing records.  They don't always occur but when they do they tend to start out as single pops and evolve into rapid pops as music gets louder on the record.  
It only happens when I use the Primare amp.  I switched back to my Cary SLI-80 amp and the problem went away, so I know it has something to do with the Primare amp.
This problem does not occur when playing other sources through the amp.  
My phono preamp is a Parasound JC-3 and my turntable is a Clearaudio Performance SEP with a Lyra Delos cartridge.  
Any ideas or theories?  I thought static was the cause but now I do not believe that is the case.  I am stumped.
Thanks!
Peter

Yes!  Very startling and lowering the volume on the amp does not reduce the sound of them.

I did not experience this when playing digital sources, only analog.  

Are you sayiong a bad capacitor in the amp or the phono preamp?  I just sent the amp in for repair as it completely lost all sound out put.  Could it be capacitor related I wonder?

I guess I will know soon.

Thanks

I couldn't tell you for sure but the signal path for digital should be the same after the preamp input jacks, so i would bet on the phonopre.  The other reason I think this is a discharge at the phonopre level would be amplified extensively especially if you are using MC carts, thus the tremendous volume even at relative mild listening levels.  I would swap in another phonopre if you can.  good luck.

Does the phono section ever do this when nothing is playing?

The Delos and the JC3 (particularly the original JC3-gain was reduced in the JC3+) are not a good match. See:

Too much output and too much gain. It's a bad combination.
