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.

What a happy end! Sirspeedy you and Atmasphere demonstrated once more how Audiogon is a nice tool when properly used. I am quite new to this site and learn so much about this magnificent hobby/passion through the great communication you guys have that I hope this will never end !

Jloveys,first off--what an interesting table you have put together!I have some friends who will be very interested in your mod.

Secondly,I won't consider a "happy ending" until I have spun some vinyl for a few,unimpeded listening sessions.

Then joy!

Thank you, Sirspeedy, this is only a humble experiment I tryed, just to see the impact of a full size platter acting as rim drive . It turned out to be very effective at no cost, exept the new superplatter.
What have you tryed yet in your system to get rid of your "pops"?
I sincerely hope it will turn to an happy end for you.

Jloveys,the apparent solution was what Atmosphere mentioned.He has superb experience,and is very well intentioned.I thought through his comments,and it coincided with my dilemma(I'd not been able to spin vinyl for about six months,due to what I thought was going to be an upgrade,with all the back orders,and reliability issues....this should end soon).The arm mfgr realised this too,and was very open to a "new" arm and cable.

thanks for the concern

Bad news, "pops" came back... I am also leaning towards tonearm connection failure, when i move the pivoting bottom of the Phantom awful pops appear.
I thought problem was resolved, but it was a short relief, maybe because I unplugged everything. Monday I take the tonearm back for checking. Fortunately we have a very good aftersale system here in Belgium and they lend me a new tonearm during repair.
