I'll try and make this short.
I've had my Dual Rectifier for over a year now. I bought it used but I believe it is the newer model since it has 5 buttons on the foot-switch. The power tubes in question are 5U4GB. Also a sign that it's the newer model.
Recently, out of nowhere, the amp lost all volume, then sparked and went dark. I could smell that something had burned up. After learning about fuses, I knew that the fuse had gone out. I then replaced the fuse just to see if the same thing would occur a second time. This time, the fuse did not go out, but instead, the power tubes were dark and at 0 volume I heard a VERY loud humming sound.
I went on a forum much like this one and every person told me that I merely needed to replace to power tubes. I had a feeling that 2 tubes going out at the same time was fishy, but I went with it. I spent 75 dollars on a pair of tubes (rush delivery). After installing them, I put the head in standby to let them warm up, and they seemed to be working. Then, the second I flipped the switch from standby mode, the same thing happened again. It sparked and went dark. No power. Possibly 75 dollars down the drain and I have a show and studio session this weekend.
Bummer.
So my question is, what is the problem? I really want to know what is going wrong with it before I drive out to see an amp tech. That way I'll know what I can afford and plan accordingly.
Thanks!
