yo
i have a Traynor YCV50B and i just replaced all the tubes in it last week. It might have 2-4 hours of playing time on the new tubes. Today i turned it on standby and gave it few minutes to warm up and plugged my guitar in and played a riff and than the amp started making a popping sound. I checked the power tubes and one was glowing orange like normal and the other was popping purple flashes, like arcs or something, that made the amp make the popping sound. Could i just unplug the power tubes and plug them back in or is there something more dangerously wrong with the tube and needs a replacement? The amp is built with auto bias so too much power going through the tube wouldnt be the answer.
Any ideas??

Sounds like you have a bad tube.

Put the old tube back in and see if there is a problem still. If there is you have a problem with the amp, if not send the tubes back and get a new set.

my old tubes were shot - both of em - so i have no replacement to check withthere was no sound at all coming out and with the autobias, usually if one amp starts to bite the dust than the aother one can take over and not affect the sound. These tubes are brand spanking so hopefully i can get a new one sent.

I highly doubt both the power tubes went bad in the old set. Try replacing just the tube that is acting up. see if either of the old tubes do the same thing.

Also worth giving the tube sockets a good clean. Pull out the tube, spray some contact cleaner (NOT WD40) liberally on the tube pins and work it in and out of the socket a few times (ie use the tube as the applicator)
