Things You'll Need:
- Tube Amp
-
Step 1
Check your guitar cable. Twisted, old or rusted cable ends will probably have shorts, so make sure that the problem lies with the amp before doing anything else.
-
Step 2
Broken tubes result in very poor sound quality and a dramatic volume drop. It's also a very quick thing to fix. Simply pull out the old tube and replace it. No hardware or rewiring is necessary.
-
Step 3
A blown speaker will still produce the same volume, but the quality will be far less than normal. Fuzzy, crackling sounds are common indicators of a shot speaker system. Repairing it takes time as it requires rewiring and calibration.
-
Step 4
Take it to a certified repair shop. The problem will require a thorough inspection by a certified repairman. If you do the repairs, you run the risk of damaging your amp beyond repair, as well as voiding any sort of warranty or protection it may have.
