Check you reverb connections and make sure your tubes are placed well in the sockets. Usually your power tubes go first due to heat and your preamp tubes don't have much trouble. Do the reverb test, tap or hit your amp. If the reverb tank vibrates, your reverb is most likely working ok.
If you amp is feeding back and your guitar's volume is zero, your input tube has probaly developed microphonics which means it should be replaced. When your amp is on, check to see that your tubes are glowing a nice blueish purple color, this is good. If they are orange or red in glow, you may have a shorted tube.
If your guitar is on, you might be too close or your overdrive or distortion is set too high -Back it off. The other is if you have cheap pickups. If you have the lower end of guitars, the pickup wires create unwanted squealing because of vibration. This is why most replacement pickups are either dipped in wax or resined. And worse comes to worse, your amp took a dive and you need to take it to a shop!
