Did I just ruin my amp

First, this is my first tube amp hence the dumb mistake.  Over the past few days my stereo has been making an intermittent high pitch squealing sound which I thought was caused by some ground or feedback issue but now see was a power tube dying.  Yesterday my wife said she heard some weird sound coming from the speakers. She called me in and I saw what looked like fire in one of the power tubes. I immediately unplugged everything and that is where things now stand. Help on what to do next would be appreciated. I have a full set of extra power tubes which I was thinking of putting in the amp but I wanted to hear from more experienced people before doing this. Thanks.

Thanks that makes me feel better. It’s an melody el34 PP amp. Unfortunately I don’t know how to replace the fuses. About all I can do is replace tubes but I am willing to learn!

As jond and twoleftears mentioned I took out the fuse holder that was integrated into the power socket. Took a look and not only does there seem to have a backup fuse located in the part that I pulled out but the original fuse seems to be intact. Perhaps I got to it before it blew.

kalali - I bought the unit used a while ago and while I believe the amp to be really well made I had been warned that the tubes that Melody included are junk.

There’s a tube cover but it looked like there was fire in the tube. I could be wrong but it was way different then normal and different than the other tubes.

I want to again thank everyone for the helpful tips. I had already purchased some preferred series tubes from thetubestore but was waiting to put those and some expensive northern electric 6sn7 tubes till after Xmas but instead threw them in and the amp sounds better than new. Can’t wait to put the 6sn7 in!
