In Reply to: RE: Russian 6C33C A Ticking Tube? posted by megasat16 on April 20, 2015 at 13:51:16
I would change out the tube. First check the sockets, though. If Chinese made they are notorious for failure. Ticking, the mechanical type is an indication that something is loose inside the glass. A grid post, perhaps a cathode. I consider ticking a time bomb and would get a spare regardless.

Yes, it's what I thought initially and changed out the tube with the new ones. I have a few extra New ones so it's easy enough to investigate.
But I can hear the ticking with the new tubes in the old socket. So, I listened closely (these tubes becoming hot very fast) and I am not sure that clicking is from the tubes or the sockets. I am going to replace the sockets too but I am wondering if anyone else have the same experience with the ticking sound from this tube.
Do the sockets hold the tube pins tightly/ in other words if you tip the amp 9 off, of course) does the tube easily slide out/ if so you do hve an issuewith the socket
Yep the Russian 6C33C tube frequently click when warming up and after shutting down. Mine have been doing it for the last 5 years. Amp is a headphone Eddie Current Zana Deux. Fabulous amp with Senheisser 800 headphones.
David, Thanks for confirming the clicking / ticking sound from your 6C33C tube during warming up and after shutting down.
