Here's some basic things to check when your amps acting up.
1. Check the basics! - Don't skip over the simple things and blame the amp right away. Check all the cables, instrument and speaker, remove all effects (loop and out front) and try just the guitar, try another guitar, try a different cabinet if possible.
2. Effects loop jacks - Dirty jacks can do all kinds of weird things. No sound, cutting out, low volume, thin tone, noise.
3. Tubes - Tubes can cause many problems. Low power, hum, crackle, volume fades, thin tone, no sound.
4. Fuses - Fuses blow for a reason! Don't keep throwing fuses in an amp, you'll just cause more damage. The #1 cause of blown fuses is shorted power tubes. If you blow a fuse try replacing the power tubes and install a new fuse (same rating) and see if that takes care of it. If it blows again, take it to the shop.
5. Bias - Bias needs to be check and adjusted if needed everytime you change power tubes. Why spend big $$$$ on tubes and not get the most out of them? If your not having your amp biased your not getting 100% out of your amp.
