What do defective phono tubes sound like?


I have noticed some rather loud energy discharges when playing LP's.Sort of an abrupt popping.Not unlike static discharge.I do not get this with my digital playback.
The ONLY change made to my system lately has been a new arm.The problem began immediately "after" it's installation.It was just fine with the previous arm.

I don't want to make this an "arm" mfgr thing(and will not mention arm name)but wonder if the phono tubes in use(very NOS Siemens CCa's,with low hours)can be the culprit.

This is making me pull my hair out,and I have little already.
Any thoughts would be appreciated.

yes to the above posts, but also, get the tubes out and clean the sockets and tube pins. I had an Audio Research unit whose sockets and tube pins had to be cleaned, and the spitting noise was no more.
